Hi,
I have just bought a Belkin USB adapter 0x050d:0x016a, and according to hciconfig this is a Bluetooth 2.1 device:
# hciconfig hci0 version revision
hci0: Type: USB
BD Address: 00:0A:3A:83:76:DA ACL MTU: 1021:8 SCO MTU: 64:1
HCI Ver: 2.1 (0x4) HCI Rev: 0x5184 LMP Ver: 2.1 (0x4) LMP Subver: 0x420e
Manufacturer: Broadcom Corporation (15)
Firmware 132.66 / 14
Does this mean that the adapter cannot possibly work correctly in anything less than a 2.6.27 kernel? Because it clearly *isn't* working correctly at the moment:
# hciconfig hci0 name
Can't read local name on hci0: Input/output error (5)
# hciconfig hci0 class
Can't read class of device on hci0: Input/output error (5)
# hciconfig hci0 voice
Can't read voice setting on hci0: Input/output error (5)
# hciconfig hci0 iac
Failed to read IAC from hci0: Input/output error
etc.
According to lsusb, this device is actually a USB hub with several other devices attached to it:
$ /sbin/lsusb

Obviously I would like to get this adapter working properly, so please let me know if there is anything that I can do to help. (Apart from fry my e1000/e1000e network adapters, that is ;-).)
Cheers,
Chris
