Can you provide the full kernel log message here please? And can you try the 5.5 kernel, 5.3.y is old and obsolete. thanks, greg k-h Created attachment 287145 [details]

Is this enough or do you need the entire /var/log/messages?
FWIW, 5.5.y kernel is found in OBS Kernel:stable and Kernel:HEAD repos (both are equivalent at this moment). Thanks. I'm just waiting for the build to finish, it's writing out the RPMs. (In reply to Greg Kroah-Hartman from comment #1) > And can you try the 5.5 kernel, 5.3.y is old and obsolete. It took a while, but: Yes, the problem still exists in 5.5.1! I'll atache the relevant part of the messages file. Created attachment 287149 [details]
Messages from kernel 5.5.1
These log messages are from the 5.5.1 kernel.
Could you give lsusb -v output of this device, too? Also please give the whole dmesg output from the boot. hwinfo output would be helpful, too. Created attachment 287159 [details]
lsusb -v output of device, dmesg and hwinfo
This is slightly different from what I remember:
In Ye Olde Days, the device would present itself as 093b:a002 and (through a udev rule), a script would be run which downloaded the firmware (through /sbin/fxload some hex file) to the device which would then disconnect and reconnect as 093b:a102.
Now I see in the journal that this is now handled by go7007-loader.ko loading /lib/firmware/go7007/px-m402u.fw!
Anyways ... infos attached.
Yes, the firmware loading mechanism went to the kernel module. The kernel warning seems fixed by correcting the urb properly like the patch below. I'll submit to upstream. Created attachment 287177 [details]

Created attachment 287141 [details] Kernel trace shown when error is reported. When connecting a Plextor ConvertX M402U video converter, a "BOGUS urb xfer" is reported and a Call Trace is dumped. I assume that the go7007 driver has not been fully supported in newer kernel versions as it definitely used to work in 2.x kernels!
