USB device disconnect and shutdown

[jrogala]

I try to make a VRS Wheel Base work via usbip. I have my host (ubuntu, fresh install) and client (windows, VRS driver installed). I can declare and bind my usb wheel base but whenever I attach to it, I lose the connection to it and I have to do a hard reboot of the wheel base (pluging/unpluging does not work).

Of course if I plug directly I have none of this and everything works fine.

I believe it may have to do with the firmware of the controller itself, but I don't have any experience on this low level stuff so I cannot pinpoint where is the problem. Isn't it supposed to be passthrough?

Here are the log:

• usbip-flt.txt

I see that the couple of IRPs (seqnum 61, 63) were not completed during the detaching, that causes this issue. I'll give you a build to test if I make a fix.

I've found a deadlock in the detach code, will give the test build tomorrow.

Please try this build https://drive.google.com/file/d/1CLo_iCieqlxLeUukgpsXGiEdGEULO8YJ/view?usp=sharing

Hello, thanks for your quick answer and build, it still does it with the newest build.

Here are the new log: usbip-ude.txt usbip-flt.txt

Thanks for your time!

I did not expect that this will fix the issue, I just fixed the deadlock during the detach. I think usbip server is closing the connection for some reason. To make sure you could set -flag 0x1F instead of 0xF in command tracelog.exe -start %NAME%-ude -guid #ed18c9c5-8322-48ae-bf78-d01d898a1562 -f %NAME%-ude.etl -flag 0xF -level 5
