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

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

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?
