Doing initial install of the Treo software for HotSync. When I get to the screen asking to hit HotSync button, it stalls and get error message on Treo saying communications could not be established. Tried soft and hard resets, reboots, uninstalls, reinstalls, etc. Tried every USB port on the PC. Windows XP Pro, Compaq desktop, Verizon unit. Previously installed on Sony notebook and it worked flawlessly. I'm stuck.
