Problem is now, that I don't have ./hcidump cause of memory problems on
this watch.
/usr/local/bin only inlcudes the following files.

I'm able to scan and l2ping to the windows xp computer!
On the windows computer I use a "D-Link DBT-120 B.4" usb bluetooth stick
with a D-Link driver (version 1.4.2.8 from the 1.4.2.10 package), cause
the original one from XP SP2 doesn't work with tihs dongle :-(
