Cannot pair A2DP speakers with Belkin Bluetooth adapter

[Chris Rankin <rankincj@yahoo.com>]

[No, I am *not* having any device conflict with the pegasus driver.]

Hi,

I have a Belkin bluetooth adapter model F8T012xx1, IDs 0x050d:0x0121

http://catalog.belkin.com/IWCatProductPage.process?Product_Id=273100

and I cannot pair it with a set of bluetooth A2DP speakers. These same speakers work fine with my laptop, which has an internal bluetooth device 0x0a5c:0x2110. But whenever I try to pair the Belkin device using the commands

$ hcitool cc <bdaddr>
$ hcitool auth <bdaddr>

then the connection drops after only a few seconds and the pairing fails. To date, I have only been able to pair this adapter with my Nokia mobile phone, after which I have been able to browse the phone's filesystem successfully.

The adapter's device descriptor is:

Can anyone suggest anything to try in order to keep the BT connection up, please? I have already tried adding the flags HCI_RESET | HCI_WRONG_SCO_MTU without any effect.

Thanks for any help here,
Cheers,
Chris
