It sure does kill your bus speed.

Disable the laptop's internal bluetooth device and buy an external dongle
that works right.
Sorry, but it sounds like the internal device won't work at a high bus

everything else run slower too. But maybe this patch will help.
Uncomment all the calls to uhci_inc_fsbr() and see if it works.
