[RFC] firmware downloader for atheros ar3011 based usb bluetooth devices

[Maksim Yevmenkin]

dear freebsd-bluetooth@ users,

i'd like to request feedback/comments/etc. on a firmware downloader
for atheros ar3011 based usb bluetooth devices.

there are actually a couple of versions available:

(1) kernel-based version. it includes a couple of kernel modules: one
to hold firmware image and another to download it. it can be located
at

 http://people.freebsd.org/~emax/ath3k.tar.gz


(2) userspace-based version. basically it is a userspace tool that is
invoked from devd(8) and uses libusb20(3) and ugen(4) interfaces to
download the firmware. it can be located at

http://people.freebsd.org/~emax/ath3kfw.tar.gz

both seems to work for me. but, i'm leaning towards userspace option
:) once again, options (1) and (2) are mutually exclusive, so, please,
only try one at a time :) please take a look, try it out and let me
know if it works. i'll probably commit something towards the end of
the week.

i also would like to thank Rusty Nejdl for donating hardware (ASUS
USB-BT211 http://www.newegg.com/Product/Product.aspx?Item=N82E16833320057
dongle). this dongle has an awesome form factor :) its pretty darn
small :)

thanks,
max
