Hi.

Try addin the module flags:

echo "options btusb fixups=0x0800000:0x000004:0x0a12:0x0001:0x8891" >
/etc/modprobe.d/csr-bluetoothbongle.conf

Syslog should show something like:

btusb: New fixups. Device: 0x0a12:0x0001/0x8891. Rule 1/1 (5 terms):
0x0a12:0x0001/0x8891
btusb: driver flags: initial => 0x0000000000000004
btusb: driver flags: masked  => 0x0000000000800000

Regards.
