In struct usbatm_driver we pass only the number of the endpoint.
Then in usbatm init, we convert this number into endpoint with 
usb_rcvbulkpipe macro.
We can't pass directly endpoint in struct usbatm_driver as we need 
struct usb_device for usb_rcvbulkpipe.

What need could do something like in usb_rcvbulkpipe to indicate if it 
is a bulk or iso pipe :
for bulk .in=(PIPE_BULK << 30) | number
for iso  .in=(PIPE_ISOCHRONOUS << 30) | number

With this usb_pipetype macros should work...

If we don't want to break the API, we could just add it for iso.

Is it ok ?

Thanks

Matthieu
