Hi all,
I am having a hard time getting my bluetooth dongle (Broadcom chipset) to work ...
A CLEAN RASPBMC INSTALL (kernel 3.6.11) generates following results:
pi@raspbmc:~$ lsusb

pi@raspbmc:~$ sudo hciconfig hci0 up
Can't init device hci0: Connection timed out (110)
But now the interesting thing is ...
On usb 1.0 speeds (by adding dwc_otg.speed=1 in my cmdline.txt. this thread #66 (comment) is a very interesting one concerning this problem) the bluetooth behavior is totally normal, so i know there is nothing wrong with the hardware.
The usb-downgrading method seemed like the perfect solution, although in one way or another, the lowered usb speeds cause 720p and up video to be choppy (streamed over network, my raspbmc installed on a SD-card).
When searching Internet it seems like a lot of people are having bluetooth/ usb related problems ...
Hoping someone could help me out with this ... (I've already done lots of research but I'm not confident enough to solve it myself ... although i would like to cooperate by doing some tests ...)
thx,
M.
