Public bug reported:
Some time ago I bought a kingston pen drive that I discovered to be a
generic crap, but at least it worked initially. Now appears that with
the latest kernels it stopped working.
Any genuine usb devices that I have works including a genuine kingston
flash drive. The only one that is not working is this generic one.

As you can see the drive have no Vendor nor Product ID.

usbtouchscreen?
Seems that for some reason the kernel is picking the wrong driver, I
don't have sure how this works or if for those generic drives any
workaround is needed, but it seems it is not working anymore.
I don't have sure with which update this happened, neither if its really
a kernel issue, but its recent as 2 months ago when I last tested it
worked.
Regards.
