ActiveSync desktop software does not 
respond to sync attempt
As you complete the following steps, 
synchronize after each step. If the 
synchronization is successful, you do not 
need to complete the remaining steps.
1 Verify that the USB sync cable is 
securely connected at all points (see 
Setting up your computer for 
synchronization).
2 Look for the ActiveSync icon   at the 
top of your Treo 750 screen and the 
ActiveSync icon   in the taskbar on 
your computer to make sure ActiveSync 
desktop software is running on your 
computer. If one or both icons if not 
displayed, do the following:
Treo 750: Press Start  , select 
Programs, and then select ActiveSync. 
Select Menu   (right action key), 
and then select Connections. Make 
sure the Synchronize all PCs using 
this connection box is checked, and 
that USB is selected from the list.
Computer: Click Start, navigate to 
Programs, and then select Microsoft 
ActiveSync.
3 Double-click the ActiveSync icon   in 
your taskbar. From the File menu, select 
Connection Settings. Make sure the 
Allow USB connections box is 
checked, and then click Connect.
4 Perform a soft reset (see Performing a 
soft reset).
5 Restart your computer and make sure 
ActiveSync desktop software is running.
6 If problems persist and you’re 
synchronizing through a USB hub, try 
connecting the sync cable to a different 
USB port or directly to your computer’s 
built-in USB port.
7 If you’re already synchronizing through a 
built-in USB port on the front of your 
computer, move the sync cable to a 
USB on the back of your computer (if 
your computer has USB ports in both 
places).
8 Uninstall the desktop software that 
came with your Treo 750, and then 
insert the Windows Mobile Getting 
Started Disc, which came with your 
Treo 750, and repeat the installation 
process (see Reinstalling the desktop 
software).
