You mean Bulk over Interrupt. BlueFW doesn't send Bulk over Isoc.

I see. I have no problem with implementation in fact it's very clean and
nice. My only concern is that if it can be done from user space it
should be done in user-space thing :). I mean nobody is going to unload
this bcm203x module after fw download is complete. Yeah it's small but
it's still a waste. I'd rather fix usbfs if it's broken. Greg and
Johannes will happily accept patches ;-).
