Usb.Net / Trezor - Error Code 121 - ERROR_SEM_TIMEOUT

Open MelbourneDeveloper opened this issue 6 years ago • 1 comments

Every second or third time you connect to the Trezor you get an Error Code 121 on one of the calls. This usually happens with GetDescriptor. If you remove any calls to GetDescriptor, it will just hang. This is also happening with WinUSBNet. I'm not sure if this is a Trezor specific problem, or something that both Usb.Net and WinUSBNet are both doing wrong...

Is there some handle or something not being disposed?

See this Trezor issue: https://github.com/trezor/trezor-mcu/issues/444

Is this a bug in the firmware?
