Hey Marcel, > what about the usb-devices.sh script output or /proc/bus/usb/devices > content for this adatper. The output for the bluetooth device from /usr/bin/usb-devices (on Ubuntu 11.04) is the following: T: Bus=02 Lev=02 Prnt=02 Port=03 Cnt=03 Dev#= 5 Spd=12 MxCh= 0 D: Ver= 2.00 Cls=ff(vend.) Sub=01 Prot=01 MxPS=64 #Cfgs= 1 P: Vendor=0489 ProdID=e031 Rev=01.12 S: Manufacturer=Broadcom Corp S: Product=BCM20702A0 S: SerialNumber=EC55F9EADE09 C: #Ifs= 4 Cfg#= 1 Atr=e0 MxPwr=0mA I: If#= 0 Alt= 0 #EPs= 3 Cls=ff(vend.)

Sub=ff Prot=ff Driver=(none) I: If#= 3 Alt= 0 #EPs= 0 Cls=fe(app. ) Sub=01 Prot=01 Driver=(none) The folder /proc/bus/usb doesn't exists here. Are the informations from /sys/bus/usb the same? When yes, which are you really interessted in (as there are plenty files for that device)? Can I provide other usefull informations?
