Missing support in btusb for broadcom dongle 0a5c:2009

Missing support in btusb for broadcom dongle 0a5c:2009

[Guillaume Bedot]

Hello,

It seems this particular dongle needs a quirk that existed in hci_usb,
but doesn't in btusb.

Is it possible to send some command to use this dongle (as hciconfig
reset can replace the reset quirk) ?

Or should the quirk be introduced in btusb too ?

Regards,

Guillaume B.

you can load btusb with reset=1 and that does the same trick, but the
quirk should be added to btusb directly. Send in the lsusb output and
content of /proc/bus/usb/devices for your dongle.

Sorry I was not clear enough...

It's a different init quirk that concern only that dongle at the moment.
With this patch it should be clearer.

This patch should allow the 0a5c:2009 broadcom dongle to work with btusb.

See this Mandriva bug for more information:
http://qa.mandriva.com/show_bug.cgi?id=44886

(and soon, for results of Jan tests especially)
