Hi all.
I got this message from my Kernel tonight when unplugging my USB
BlueTooth adapter form my laptop. It WAS working fine, then suddenly
after transferring about 10 files using kbtobexclient, I kept getting
messgae about unable to connect transport frm the obex client software.
Upon unplugging the adapter I got the following in my messages file...
Thought someone might be interested...
