ath9k_htc does the same thing (see ath/ath9k/hif_usb.c).
It does seem to be working properly but I am wondering if the
USB subsystem has to be updated after the driver messes around with
bmAttributes.
(lsusb would still show the endpoint type as INT).
You have a usb_reset_configuration() call before changing
the endpoint type, why is that necessary ? And would that
reset the endpoints as well ?
Choosed to place intr->bulk change after reset as that seemed less
likely to wrong. Tested in the other order and that works too.
