Mate! Why didn't I think of that? I just set the decode of tcp port 3240 to USBIP... I didn't realise it had that, but of course it would because I've used Wireshark in the past to snoop proper usb when reverse engineering a Wi-Spy. I didn't even think of this. Cheers.

USB-IP has a Windows client I believe.

Exactly!

Yeah man, that's why I get all the chicks!

Thanks. I had already resigned to the idea that no such device existed and I'd have to find a way to pull another dedicated ethernet cable someday (i.e. when I finally move my gaming PC from being in the next room to being in the basement). However, seeing the price of the Silex, I'm not sure if being too lazy to move the PC isn't the better option after all... ;)

There is a commercial, albeit really inexpensive, solution that has worked well for me. As far as I can tell, it makes use of some of the same kernel modules that this video documents. But it then implements the server in user-space and implements its own wire protocol. And as opposed to the basic kernel modules, it also adds support for Windows and MacOS, and it conveniently provides a user-friendly GUI app. You can even get an Android app that allows you to plug your USB device into your phone and then make it accessible over the network. And if you want to access your USB devices across the internet, it provides discoverability and encryption. Do you have to buy a commercial solution, when you might as well use the built-in tools that come with your Linux system? No, not at all. But since it's a small one-time payment, I found it a useful addition to my set of tools that I usually keep around. And honestly, the free feature-restricted mode that it has is frequently good enough for one-off experiments. Search for Virtual Here, if you are interested. N.B. I have never used this product with bandwidth-intensive USB devices such as cameras or mass storage. I have no idea how well that would work. A wimpy little Android phone or a tiny SBC is likely not powerful enough to encapsulate all that data in IP packets. So, try the demo version before shelling out money to make sure your use-case is supported. But for the particular needs that I have, it's an awesome little tool.

Haha, then you'd love my OnlyFans :)

Haha, you know somebody will probably try that. As I say that though, I guess it would actually be okay if the USB NIC is only running low bandwidth that the main link could handle. Obviously that would be backwards, but there may actually be some crazy corner case where that might come in handy for someone. Who knows.

Right, I'm keenly interested in what the limitations are.

@@TallPaulTech Yeah there has to be some compelling use case out there - Pi with a USB ethernet adapter that you can just drop in as an isolated remote debug port? Jumping over a host you don't have network config access to? Who knows. Sidenote, would love to see you do something on using a Pi as a router-on-a-stick if you have the interest. I had an edge case of wanting to do PPPoE termination on a Pi router-on-a-stick style and guides for even the most basic configurations of the concept on a Pi were difficult to follow.

Mate, are you new here or something? kzfaq.info/get/bejne/bdiZfc6hmteVXYE.html

This thing is telling me you've been here for 7 years!

I know you were... because your Ring doorbell leaked your private comms to me!

@@TallPaulTech not unless it could literally read my mind haha but seriously, was about to go searching for a way to remote access a card reader next to my 3D printer so I didn’t take my devices SD card into my office and lose it again.

Join the club

No, but let me know if you have any Wireshark questions/ideas

Next I'll have your mamma!

@@TallPaulTech 😁

I haven't seen usb over cat5 (although this technically is), but it sounds messy.

Somewhere around 10' is really the maximum that regular USB can do over copper. If you want to go any longer, you need to have active cables. There are various products that do this. Most of them seem to convert to fiber optics for the long haul and then back to electrical signals. That's the same trick that extra-long HDMI cables use. You occasionally see products that convert to their own proprietary signalling protocol and then allow you to use CAT-5, but that seems to have mostly fallen out of favor these days and I don't believe anybody ever managed to get more than USB 2.0 speeds over CAT-5. Active cables with internal converters work beautifully, if you want something that behaves as similar to a physical cable as possible. It's nice in how you just plug it in and forget about it. But for more flexibility and features, encapsulating in IP is the way to go. It might require more tinkering, but it often turns out to be less expensive as you might already have everything you need.

@@gutschke right on. i didnt put much thought into what twisted pairs i was using for what. im sure the twists themselves were messing with me too. as the cable got longer.

It should work for anything.

Bloody hell, I haven't heard that in a while. Team America won't get that.

Indeed it is

You didn't need to edit that on the end... there's only one voice that comes to mind when reading 'marvellous'. The edit only shows that you're Australian :)

@@TallPaulTech no my friend, a Brit, and ‘marvellous’ here in faux-Benaud means you blagged a 9th gen bootleg tape of The Twelfth Man off one of your mates. Hence I felt I might have to explain. Just in case. Good job you got it then.

Blagged?... Speak English to me Tony. I thought this country spawned the fucking language, and so far nobody seems to speak it.

Let's see if you know what that's from.

@@TallPaulTech Tony as in Bullet-tooth Tony, portrayed by our very own bollock-grabbing hero Vinnie Jones in ‘Snatch’? Oh, you don’t know about the grab? Google ‘Vinnie Jones Paul Gascoigne’. Likely never been heard of down your way.

You don't do silly things like use Windows do you?

My company uses AnywhereUSB to mount license dongles to Azure servers, and it does cost money :)

Even better, do that then join the ends and make a loop :)

Hang on, what did you miss?

@@octopusdreamsDo you see my reply? Or has this crappy KZfaq spam filter which filters everything but spam caught it?

@@octopusdreams Yeah, I wrote two paragraphs about the thing I use. Anyway, I use "USB/IP Server" app from Google Play. Works without root and behaves like a normal usbipd server, so use a WireGuard tunnel or similar to connect to it from your PC.

@@octopusdreams Okay, one last attempt. This is Incredibly frustrating. I use U S B slash I P Ser ver from Pl ay Store. Doesn't even need root.

I don't know why I had to specifically authorise your comment then. KZfaq is getting worse. I just saw one on github called usbip-win which has basically the same syntax and seemingly structure, so maybe, just maybe it will work on a Windows client to a Linux server. I'm sure someone who actually uses Windows could check and find out.

@@TallPaulTech that is odd. I've re-read my comment, and not even a "stackoverflow" moderator would be able to find anything to complain about. :D

blown would do it

@@KieranShort and yet you just said it????

If it's a USB device, I don't see why not.

Sounds like you should be able too (haven't tried myself). Keep in mind that network latency is a big factor as mounting a Serial BUS over a network is much slower than a direct line to the CPU. As long as the threshold is within that latency window of the network it should perform just fine. The DAW running on the client will have no idea that device isn't local and nor will the kernel for that matter.

What kind of update? It's just dvblast sending out multicast.

@@TallPaulTech awesome! I'll look into how to set it up, I've been looking for a multi tuner setup over multicast. Thanks

You've got to be kidding me, right?

It would be about the same bandwidth as whatever device you're using is.

What USB application are you using that really requires that bandwidth in real time?

@@TallPaulTech Just thinking out of the box here (not sure if its actually realistic), but for example hdmi video. A 5Gbit USB-C to HDMI adapter isn't able to drive my external monitor (needs to be 10Gbit), so there are a few applications that require substantial bandwidth. Even with a 10Gbit network you wont be able to push anything close to 10Gbit over a single TCP connection. Doesn't make this any less of a cool solution, but there may be limitations to the data you can push.

No. If you cop a direct lightning strike, then everything is going to be pretty fucked anyway so I'd be more worried about the missing roof. Those lightning suppressors you see are for discharging the excess radio energy that's in the air during a storm to ground, to save it blowing the front end of receivers. A full lightning strike though?... forget about it.

@@TallPaulTech true, the radio gear would be collateral damage compared to the damage to the roof I suppose.

Same here actually. It wasn't until I needed to do this that I thought, surely this must have been thought of already, and it was.

@@TallPaulTech this is witchcraft. Very cool witchcraft

@@octopusdreams Hi, from what I have been searching, I could not find a Bluetooth repeater..... Should be easy with Linux. If you know any Bluetooth repeater, please let me know. Thanks

Fair call

I use Debian for everything.

Why not?

No, that's not possible with USB/IP

USB itself doesn’t allow device sharing.

@@lawrencedoliveiro9104 yeah but you might be able to T off the data stream and relay it to multiple clients

@@BandanazX USB doesn’t work that way.

No, that would make no sense.

Where did you see Ubuntu? I don't use that.

@TallPaulTech I don’t think you have specified what versions of software or operating systems you are using at all, its important because if you are using Linux distributions, many of these can be buggy and unstable, same goes for Raspbian.

Use VPN if you need encryption

I meant inside my own network. My threat model is "assume breach".@@AgentOffice

On physical level (hardware) in both cases (usb and ethernet) only crc checking or ack (acknowledge) bits can help but this is not adequate in both cases. CRC (sum of data bytes send) maybe ok, ACK (other side says i have received the signal like in a CAN-BUS) but what about data ? Data can be corrupted and must be checked with software and in same cases it can be very slow and timeconsuming for both of them. So it depends on the case, TCP IP (software protocol ) controls and verifies packets strictly because they come from other side of the world but UDP streams (internet radio, movie etc..) are not controlled. Likewise we can make many software layers on USB, we can choose control it or not. For example an sdr device sends I and Q float data over usb very fastly there is no time to check them. Physically in same cable there can be many usb devices (nodes) communicating at the same time for example 20 mouses, its packets can not be checked and one would see errors (not latency actual errors) on their data because mouse data is not controlled by software. But on same ethernet network let say 255 devices can communicate with internet, there would be latency but no error if they use only TCP only because software layer handles it. On a bus (can bus,usb etc..) we can only check some bits, crc in hardware level and it is not enough to make them error prone.

USB does not permit device sharing.

The usbip command is in the linux-tools-generic package in Linux Mint 21 / Ubuntu 22.04.

Ham radio?

I might categorise some of my videos into playlists actually.

@@TallPaulTech I'll go thru your vids and check it out. I have two SDR running on a Raspberry Pie 4 8gb in my shed in a clear lid weather proof box that drilled some 2" holes in and put an intake and exhaust fan on it with pass thru connections. Iive in PHX, so no need to worry about rain or anything. As 360 days of the year is bright and hot shinning sun. LOL. I am running a 978 and 1090 Mhz bands SDR for ADS-B feeding adsbfi, ads-B exchange, FR24. I am able to view a out the entire southern half of AZ and into Cali with my antenna setup. I can't go to high as the HOA will kill me. :)

Most usb devices I've seen use the bulk transfer method, so should be fine I guess.

@@octopusdreams i don't have a pc connected at the remote end. The software is used to configure the device once, then this device will be deployed to the location. The device only has means to be connected via usb.

@@octopusdreams "get a raspberry pi or a cheap android phone or something" this was the whole point of my doubt. I just want the device at the remote end. I could put a rasp pi or android but i can't. that's where i'm stuck.

@@octopusdreams I'm stuck on money. Can't afford a rasp pi

@@octopusdreams thanks... I'll check this out

@@octopusdreams $16 is still a long deal.On the contrary, can i not just use usb-over-fibre optic ethernet adaptors? Didn't read much about this, but throwing it in here cause it'll save me some time to look for maybe other alternatives.

Well that's a bit hard to say without some very fine details. It's something I'd (ie, you'd) have to look right into with packet captures and stuff.

@@TallPaulTech Thanks for the response, another issue I'm having which I will msg on the Tesla CAN Bus Raspberry Pi thread.

@@TallPaulTech , thanks for the response, can you please check out my post on your Tesla CAN Bus Raspberry Pi thread ?

That's a good question actually. You'd think that if the hub was on there, then its subordinates would come up as dash= something but I'd have to try it.

What?

I saw that, but usbipd-win seems to be just the usbipd command allowing it to be the server but not a client. I did a quick test and got a Linux client to use a Windows server device, but not the other way around because there was now Windows usbip command by itself that I could see.

@@TallPaulTech 😢

I think there are products you have to pay money for. Windows cannot manage it on its own.

In theory you might be able to run Linux as a guest under VirtualBox on a Windows host, use VirtualBox to attach a host's USB device to the Linux guest OS, then in Linux run the appropriate usbip commands. Performance might not be great but it might be good enough.

They simply mean, harden up.

I had to go back and watch the first 45 seconds and when I listened I thought.. 😂 i get it

How is that a problem? USB 2 can handle my fastest device which does 350Mb/s. What USB device are you using that needs over 1Gb/s?

2.5GigE is becoming really cheap these days, and 10GigE is well within reach for desktop-style computers or servers, but not necessarily a great option for mobile devices yet. You can go faster than that (e.g. 25, 40, 100, ...), but that tends to get more expensive and might have diminishing returns. Having said that, I can't really think of too many applications where I would want to encapsulate USB over IP and max out my network capacity. But then, your use-cases could very well be different from mine.

Huh?

check pi-kvm i suppose
