[Bluez-users] Targus ACB20EU: Scan times out

[Arthur <arthur_vd@gmx.net>]

Hello all

Scanning for other devices with the Targus ACB20EU USB dongle (a 
bluetooth 2.0 adapter with EDR support according to the packaging) 
always times out. It doesn't help to run hcid or hciconfig hci0 up 
beforehand. This is how it looks like:

# hcitool scan
Scanning ...
Inquiry failed: Connection timed out

Running hcidump -X -V at the same time only yields this output:

# hcidump -X -V
HCI sniffer - Bluetooth packet analyzer ver 1.32
device: hci0 snap_len: 1028 filter: 0xffffffff
< HCI Command: Inquiry (0x01|0x0001) plen 5
     lap 0x9e8b33 len 8 num 0
 > HCI Event: Command Complete (0x0e) plen 4
     Inquiry (0x01|0x0001) ncmd 1
     0000: 0c

hciconfig -a gives an input/output error:

# hciconfig -a

Can't read local name on hci0: Input/output error (5)

Here the associated dump:

# hcidump -X -V
< HCI Command: Read Local Name (0x03|0x0014) plen 0
 > HCI Event: Command Complete (0x0e) plen 4
     Read Local Name (0x03|0x0014) ncmd 1
     status 0x0c name '.'
     Error: Command Disallowed

This is on a 2.6.17-10-386 kernel on Ubtuntu Edgy (2006.10).

Any ideas or suggestions are heartily welcome.

Regards

Arthur
