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. lsusb: $ lsusb ... Bus 003 Device 002: ID 1234:5678 ... As you can see the drive have no Vendor nor Product ID. $ dmesg ...

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.
