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

Hi Mitch,

Quoted 7 lines

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;

Quoted 6 lines

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.

Regards

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?
