Hi,
Just bought one of these, but doesn't seem to work on 2.6.0-test11.
syslog spews out:
Bluetooth: HCI socket layer initialized
Bluetooth: HCI USB driver ver 2.4
hci_usb: probe of 7-2:1.1 failed with error -5
drivers/usb/core/usb.c: registered new driver hci_usb
Tried adding the device id's to hci_usb.c in vain.
Any ideas to get this beast working ?
Thanks
Mitch

your dongle should work out of the box. Have you tried 2.4.23?
Do you have a /proc/bus/usb/devices for us? It should show you something
like this

Hi Marcel,
Yup i do have an entry (see below), and i've managed to get it to load, but by
hacking the hci_usb.c to remove the lines
/* Check number of endpoints */
if (intf->altsetting[0].desc.bNumEndpoints < 3)
return -EIO;
It looks like since there's multiple interface descriptors for the device (see
attachment), and bNumEndpoints is only equal to 3 in one of them, then the test
fails and returns EIO. I don't know if this check should be removed altogether since
we subsequently iterate thru all the interfaces to get the endpoints.
hciconfig shows me 2 interfaces - is this correct ?

this is wrong. The second interface on the USB layer is for the SCO
audio support and in normal cases correct recognized by the driver. This
is why the above check is in the code. If you not have three endpoints
on the first interface it is not a USB Bluetooth device. Please check
your device with 2.4.23.

Marcel

Ok, thanx to Marcel, i looked again, and no patches/source code changes
are needed. The error
hci_usb: probe of 7-2:1.1 failed with error -5
is spurious, and the device still works just fine.
Another one to add to the list of working with linux bluetooth devices ;-)
Thanks
Mitch

these kind of errors sometimes happen. The USB folks should know more
about them.

Please send me "hciconfig -a" and do you have a full product name or
weblink?

now I got it. We are the origin of this error and I think simply return
zero is the better approch, because it is not an error on interface 1
and 2 (if you have support for DFU). I put it on my TODO list for 2.6.

Marcel
