I'm using the usb-uhci driver (this will also happen on the uhci driver) on vanilla kernel 2.4.26. Problem will not occur in 2.6.x
When sending an urb down the interrupt out pipe, it will succede the first time. But then the next time I try this, usb-uhci will give me this error message: this occurs on or near line 1664 of usb-uhci.c usb-uhci.c ENXIO 40010200, flags 0, urb cf5734a0, burb cf573c20 test_int_urb.c: usb_submit_urb failed with status -6 Apparently it means that there is already an urb queued for this pipe....although I tried timeouts to wait for the urb to finish....it seems to be stuck in the queue/pipe ... I also tried this with an urb_pool which will use urbs in the pool that don't have -EINPROGRESS status. Same thing is happening, except the first urb in the pool will succede and the next urb (the first sent urb shows a status of -EINPROGRESS, while the urb allocated for writing has a status of 0) will fail. After the error message, nothing else can be sent down the pipe as it claims there is already an urb queued. I was looking around in drivers/usb/ for example work using usb_sndintpipe, there aren't many. (only 1, auerisdn_b.c) What is the basic layout for how I should be submitting multiple urbs with usb_sndintpipe? The below is part of a loop in the particular function... struct urb *urb; int pipe; pipe = usb_sndintpipe(udev, endpointaddress); <-- these are valid.... urb = usb_alloc_urb (0); usb_fill_int_urb(urb, udev, pipe, buffer, len, callback_function, context, interval); <--these are also valid usb_submit_urb (urb); I'm sure that something is missing on my part.
