Hello!

Yes, it looks like this.
I am no expert in this area and cannot tell exactly.
I can only suggest a practical way to test the patch: you take some USB flash
(the older and the slower is the better, usb1.1 flash is the best),
then do the following:
for (;;) {
usb_detach_kernel_driver_np(handle, 0);
usleep(1000*(random() % 10000));
usb_attach_kernel_driver_np(handle, 0);
usleep(1000*(random() % 10000));
}
(handle is libusb handle for the device)
Unpatched kernels crash almost instantly.
Alexey
