and this is what I mean. They don't read the H:2 spec. and push out an
invalid product, because at least it must have this entry:

I:  If#= 1 Alt= 0 #EPs= 2 Cls=e0(unk. ) Sub=01 Prot=01 Driver=hci_usb
E:  Ad=03(O) Atr=01(Isoc) MxPS=   0 Ivl=1ms
E:  Ad=83(I) Atr=01(Isoc) MxPS=   0 Ivl=1ms

You can use one of my patches with this changelog entry

	- Quirk for devices with no ISOC endpoints

or you disable SCO support for the hci_usb driver at compile time.

Regards

Marcel
