First I install the Clie TG50 and all syncs fine through USB. Then I install 2nd user for the Treo 600, and the Treo syncs just fine through the 2nd USB port. After a few syncs with the TG50, the USB connection just stop responding, nothing happens on the PC and the TG 50 hangs. The Treo syncs fine after the TG 50 stops syncing. Any ideas of how I can get the TG 50 to be recognised again. I am using one, the same, USB port for the Treo and the TG 50 respectively. Thanks for any advice.
