Belkin F8T065 doesn't register properly (BCM20702A0)

[Maksim Yevmenkin]

hello!

>> I have a Belkin Mini Bluetooth v4.0 dongle (F8T065)[1]. It seems to be Broadcom BCM20702A0 based, but it doesn't register correctly.

ok

bDeviceClass (0xff) is not matching  UDCLASS_WIRELESS (0xe0). most
likely it needs some sort of firmware to be loaded first.

it probably needs firmware to be loaded first. you might be able to
locate firmware, and, possibly hack on bcmfw(8) in the source tree to
get it to load.

if you have windows driver try to look at .hex, .img, .bin or
something like that files. one of those might be the firmware you are
looking for. of course, like i mentioned before, you need to hack
something to load firmware. older Broadcom chips can be loaded with
bcmfw(8). so its a good place to start. if you can't get it to work, i
could take a look but i would need access to hardware.

thanks
