Ubuntu Linux USB Bluetooth Adapter Problems

Let's hope this post will be found by anyone having problems with USB Bluetooth dongle under Linux. I bought "Sweex LE000010" model which seems to identify itself as "Broadcom 2035" (lsusb id 0a5c:200a). I knew it probably won't be easy to work with it under Linux but I had more significant problem - I was not able to communicate with the device at all (allthough it was detected).

After several hours, when I was getting really desperate I found the solution: The dongle has to be plugged directly into the computer, not into the USB hub!!!!!! I have no idea why but it's true. When I plugged it directly into the PC, it immediately started working without me having to configure anything (btw: The defauld PID for synchronization with the PC is "1234").

Now for the second part of problem: Does anyone know how to configure Nokia 6681 to connect to the internet through my Bluetooth/enabled PC? (Not connecting my PC to the Internet through the Nokia - the other way around!)

Re USB Hub - maybe the hub itself is USB2, but provies only USB1 ports?

Windows: mrouter
Linux: gnubox - http://gnubox.dnsalias.org/gnubox/

jtk: Thanks, but I need it only for testing the sommunication with SyncML server and it seems the method described there does not work with the SyncML application on 6681. :(

Just an idea - is the hub itself powered? Some USB devices require to work properly a powered USB hub althought they may be seen as connected. (but this is just a shot into the dark)

petr: Yes, that might be it. But I have 6 other devices connected to that hub, some of them rather exotic, and all work without problems.

This is well-known problem that some devices claim that they require more power than they really need. Port in PC or port in powered hub is able to give 500 mA, port in unpowered hub is able to give 100 mA. There is software mechanism which don't allow to enable device in case that it cannot be powered.

Interesting story as for me. I'd like to read more concerning this matter. The only thing your blog misses is a photo of any blocker.
