Immediate disconnection upon connection with "Error 22 discarding urb", windows to pi

Submitted by opherv on #1

Hi,

I'm testing out VirtualHere to connect to audio gear remotely for setup purposes. No audio is transferred over USB only configuration, so the issues I'm having shouldn't be bandwith related.

The client is running windows and the server is on a Raspberry pi 3b+

Upon connection, I get a disconnection with the following logs.

Server:

and so forth..

Appreciate any help in debugging this

Cheers

Its almost like the usb controller on the pi3b has crashed because the network drops at the same time (they are both on the same USB port on the pi cpu)

If you run uname -a on the pi what does it say?

Uname -a result:

Linux DietPi 5.15.76-v8+ #1597 SMP PREEMPT Fri Nov 4 12:16:41 GMT 2022 aarch64 GNU/Linux
 

Note that this is a fresh DietPi installation after the exact same issue happened with a RaspbianPi distro.

Also, a mass storage device (thumb drive) seems to work just fine.

That kernel should be ok, i dont know the issue sorry. Sometimes if you plug a powered hub between the pi and the usb device it helps. If you have a spare separately powered USB hub put it between the Stomp and the pi

Interesting. The Stomp device itself is powered so I doubt it has to do with that but I'll check!
I'll also check with using the LAN port to see whether it's an issue with wifi on the PI

Ran some tests
First disabling the wifi controller completely and using only wired LAN. Same exact error - so it's not a "weak wifi" issue.

Then tried with a different charger, and also with a powered hub, measuring voltage and amperage using a USB tester..
Both times it's never above 0.52 amp (and both chargers supply 2 amps)

If you have any more ideas on how to test/troubleshoot I'll be happy to... I'm really hoping to get this sorted out and purchase the server :) 🙏

Email me know if you want me to take a quick look via teamviewer when you are there,perhaps i can see something if i have a quick look around on the pi and /or client pc.
