Hello Oliver,
I am sorry, but I think I don't understand ,
You said:
>A USB driver never will request an irq. Interrupt handling is done in

but in the zd1211 driver (not the rewrite version) I found this
call to request an irq:
request_irq(dev->irq, &zd1205_intr, SA_SHIRQ, dev->name, dev)
Also when looking in the linux tree, I see some request_irq() calls in USB
drivers, for exmaple in some drivers under usb/gadgaets, and more.
Can you please elaborate a bit ? What do you mean by saying
"A USB driver never will request an irq"?
