85110 - ECHO/PULSE - Computer froze using Windows Livescribe Desktop
Why did my system lock up when I tried using Windows Livescribe Desktop?
Please see 80903 - ECHO/PULSE - System requirements for Echo Desktop
If your system is compatible and Livescribe Desktop works but freezes when you dock your smartpen, then try plugging the USB charging cable into other USB ports on your computer.
If that does not resolve the issue, try plugging the charging cable into a powered (plugged into an electrical outlet) external USB Hub (if you have one).
If this doesn't help then there may be an issue with the USB board in your computer. You may want to check with a computer technician to diagnose your machine for hardware issues.
