just as i suspected. the device does not present second interface with 
usb isoc. endpoints. imo, this violates bluetooth v1.1 specification 
(chapter h2).

the reason it works on linux is because hci_usb driver treats isoc. 
endpoints as optional and does not insists on them being present (isoc. 
points are usually used to transfer voice data).

ng_ubt(4) could be extended to add quirks for some devices. however, i'd 
have to get my hands on the broken device so i can write and test the code.

in the mean time, you could hack ng_ubt(4) to make sure it does not 
require isoc. endpoints. if you get it to work, please post patches here.

thanks,
