Hi Christoph,

build your own Debian kernel package.

Yes, it does, because Telencomm is Zeevo. This is the TC2001 as I
expected and maybe this chip is not really a good choice for your
"viper" system. If your problems is still there after you have upgraded
your kernel, try to get a CSR based dongle and see how it goes.

BlueZ L2CAP and RFCOMM socket programming is mostly the same as if you
are using a UDP or TCP socket.
