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
the core usb layer. Individual drivers have no business there.
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"?

A USB driver never will request an irq. Interrupt handling is done in
