thanks for the information

i disagree :) it gives you vendor/device id pair which is
0x0cf3/0x3000. in other words, your adapter is based on atheros ar3011
chip and will require a special (new) driver that would download
firmware. ubtbcmfw(4) will not work, because its for broadcom chip. i
only mentioned this because it would be similar, but not the same :)

1) need to write a special ubtathfw(4) driver;

2) obtain firmware (i assume it would be on a cd that came with the dongle);

the good thing is that linux 2.6.33.7 kernel already has firmware
driver, so, it makes it easier to port. i can probably take a stab at
it, but, without device, you would have to test it (and likely to
crash your machine several times :) are you up for it?

thanks,
