Subject: [Bluez-users] 2.6.2 errors with DBT-120 (B2)

Hi all,
I have been attempting to get SCO over HCI to work... I have a D-Link
DBT-120 (B2). When I startup hcid, I was getting the following error
message:
hci_usb_isoc_rx_submit: hci0 isoc rx submit failed urb de96e614 err -90
hci_usb_isoc_rx_submit: hci0 isoc rx submit failed urb de96e614 err -90
It appears this occurs since the hci_usb driver is picking a bogus
endpoint with a wMaxPacketSize = 0 when submitting the urb.
Attached are a few files for assistance:
hciconfig.txt 'hciconfig -a'
lsusb.txt 'lsusb -v'
hci_usb_sco_debug.log.gz Debug logs from /var/log/messages
patch-2.6.2-tj1.gz a patch
The attached patch includes patch-2.4.24-mh2, a fix for the error, and a
few minor fixes so the kernel can build when debugging is enabled...
This does not fix SCO support, It simply assists in getting an endpoint
where wMaxPacketSize != 0.
Here is the critical part, or what eliminates -90:
<patch>
diff --unified --recursive --new-file linux-2.6.2/drivers/bluetooth/hci_usb.c linux-2.6.2-tj/drivers/bluetooth/hci_usb.c

#ifdef CONFIG_BT_HCIUSB_SCO
case USB_ENDPOINT_XFER_ISOC:
- if (ep->desc.wMaxPacketSize < size || a > 2)
+ if (ep->desc.wMaxPacketSize <= size)
break;
size = ep->desc.wMaxPacketSize;
</patch>
Now that the error is gone, SCO still is not working. Since I enabled
debugging with this patch, I was able to capture additional data to
assist someone whom knows much more than I in fixing the SCO over HCI_USB.
If I'm completely clueless, please disregard, and sorry to waste your
time! Thanks in advance!
Regards,
Todd E. Johnson
