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 ?

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
