Hi,
I've got a USB bluetooth adapter that needed some of those handy module
params to get SCO working.
Bus 001 Device 004: ID 0a5c:2121 Broadcom Corp. BCM2210 Bluetooth
I'm running on 2.6.26-13 from debian lenny, with an sco.ko with an ESCO
disabling patch, but I also tried it on 2.6.28.7 (with disable_esco=1).
It seems to be required that force_scofix=1 be on, but I noticed none of the
IDs only contain the SCO fix (http://git.kernel.org/?p=linux/kernel/git/holtmann/bluetooth-2.6.git;a=blob;f=drivers/bluetooth/hci_usb.c;h=3c453924f8386c9b92050ae978967d188ec3b4da;hb=57f8f7b60db6f1ed2c6918ab9230c4623a9dbe37#l105) so I added
the reset=1 as well.
Let me know if you need more information about the bluetooth adapter or the
headset that I am using.

send "hciconfig -a" before and after your patch. You have to prove to me
that you really need this patch.
Also please post a patch against btusb.c since hci_usb.c has been
removed.

please post the content of /proc/bus/usb/devices for that dongle and
also please send patches against bluetooth-next-2.6 or net-next-2.6

I didn't actually patch hci_usb. Since the options were there, it was
easier to use them. As requested, I've gone back through gitweb to pull
this file to patch. See attached.
