Bluetooth adapter not working. RHEL5


Hello, I am trying to get my bluetooth adapter to work in RHEL. The adapter is a Kensington Micro (K33902US). The system detects the device, but it fails to find any networks when I do a scan using hcitool. Also, I wrote a small C program to do the same, with the same results (no network found). The bluetooth manager appears in the panel, but when I right-click, the only option I have is to check/uncheck "Discoverable". I have tried restarting bluetooth using "service bluetooth restart" to no avail.

I tried borrowing an adapter from a friend (some DLINK) that seemed to work fine for both hcitool and my program. The problem just seems to be in Red Hat's ability to use this particular device.

Please advise and thanks.

*Edited to fix smilies*
Update:

I am able to pair the device with my MacBook Pro. If I do 'hciconfig hci0 commands', it give a large list of commands.

'hciconfig' output:
hci0: Type: USB
BD Address: 00:1B:DC:0F:4B:A6 ACL MTU: 310:10 SCO MTU: 64:8
UP RUNNING PSCAN
RX bytes:4288 acl:0 sco:0 events:124 errors:0
TX bytes:2522 acl:0 sco:0 commands:114 errors:0
The 'events' and 'commands' counters increase properly each time I issue a command.
