hello,
i am still trying to write my driver, but i got into problems.
When i try to do a bulk out operation, i get this error :
usb-uhci.c: interrupt, status 3, frame# 945
usb-uhci-debug.h: TD @ c15fbd20/015FBD20, MaxLen=34 DT0 EP=7 Dev=3
PID=( OUT ) buf=09cb77a0
usb-uhci-debug.h: Len=34 e0 SPD IOC Stalled CRC/Timeo
usb-uhci-debug.h: TD Link Terminate
does this mean the endpoint is stalled ?
if so, what can cause this ?
can it be something with alternative settings of an interface?
is there a way to get more information ?
I am using kernel 2.3.99-pre2
I also have a similar problem with a control message.
The device requires firmware to be downloaded, before the firmware is
active, the hardware will accept and even acknowledge the setup packet,
but will never reply...
I tried to use this to poll whether the firmware was up, but this didn't
work. The messages times out nicely, as i want them to, but when the
firmware is downloaded, the control messages still time out...
(btw: i use a 1s timeout)
any idea's ?
thanks,
J.
