Help! Need to Sync with Mobile 5 AND CE 2.11

[dLindley]

I need help finding a software product that will allow me to synchronize with my Windows Mobile 5 device AND my Handheld PC Windows CE 2.11 device (Clio). I've tried Activesync 3.6, 3.7, 3.8, 4.x with no success.
Any suggestions or ideas would be GREATLY appreciated!
