Hello, I have trying to find more hints about this problem and all what I found so far did not help.
Basecamp does not find my GPS.
Here are the SW versions
Macbook Pro 13": 10.8.3
Basecamp: 4.1.2
GPSMAP276C: 5.50
Garmin Communicator Plug-in Version 4.0.4.0
and what I tried already
The GPS is recognized with basecamp on a Windows PC (same cable).
The USB is working e.g. USB stick, mouse, camera - all ok
called Mac hotline - gave a special restart (ALT+CMD+P+R)
Any idea what now?
terv.
