New USB driver & API (updated)

[Molnár Csaba]

I have tried your patches - and for the first time, device nodes were created 
for my USB Ipod-Mini. Previously, it worked only when atapicam was not built 
into the kernel. It was recognized, but no device nodes were created. 
(fireware ipods worked fine).

On the other hand, my usb stick froze my computer, during file operations 
(copy, delete). This was the console message I got:

umass0: SCSI over Bulk-Only; quirks = 0x0000

System is 5.4-STABLE (world and kernel built 2 weeks ago).
