Hi All,

I am using DBT120 dongel and Motorola HS850. I am able
to connect with RFCOMM and SCO channels. But sometimes
i get following errors when i switch headset off and
on.

Can't connect: Resource temporarily unavailable
(11)
Can't connect: Function not implemented (38)

After this i have to remove the dongle and restart
the machine to get it to connect again.
Pls help.

thanks, Manoj
