Hi,
I'm currently using 2.4.5 kernel on an Assabet like board. While the host
controller (ohci) and root hub seem to initialize correctly, I have problems
connecting devices to the hub. I receive errors 32 and 110 (EPIPE,
ETIMEDOUT) when hub.c tries to attach a new device (usb_new_device()) and
set the device address (usb_set_address(), from usb.c):
"USB device not accepting new address=xx"
I'm trying to duplicate the functionality of the funtion pointed to by
submit_urb() (from struct usb_operations) but am not sure where (or how)
it's implemented. Is there a way to manually send package and send URBs to
test if I can read some control reg or something like that?
Thanks,
Neil

Of course, but at this time that's not that important. I know the firmware
file is correct, and want to test the upload part first. I'll get into the
nitty gritty after that's working. :)

And a good one. I'm just not that far yet, I want to get rid of those
timeouts first. I'll get that checksum after that... :) It hasn't got the
complete DFU state machine yet either.
Thanks for the input,
