Writing 127 to FADDR breaks driver. It can't even attach device properly.
I do not completely understand the scenario behind this requirement. My
recollection is: when we cancel IN transaction somehow we should ensure
that function that currently handles it does not stuck forever. From what
I see it's just impossible. There is internal NAK timer that fails the
transaction
once it reached configured value (or 3 by default AFAIR). Isn't it enough?
I tried unloading active uwrtn driver - it unloads with some delay but as
far as I can see from logs delay is not due to USB internal transactions code
it must be upper layer.
Could you, please, elaborate on the matter?
Here is updated version of the patch:
http://people.freebsd.org/~gonzo/arm/patches/beaglebone-usb-20130701.diff
Besides cosmetic fixes I also synced dev/usb/controller/musb_otg_atmelarm.c
to the latest changes of core logic: added required wrappers and some
initializations.
I do not longer have access to USB analyzer so my debugging abilities
is somewhat limited now.
