VZAccess Manager hangs mouse & keyboard on Mac OS X when plug in LG enV

Question

I have installed VZAccess Manager to use a USB760 wireless broadband modem on my Macbook Pro and it works fine (note this is one of the newest Macbook Pros, with the i7 processor).
I also plug in my VZ LG enV cell phone via USB, but not to use as a modem; only to charge it.
However, what happens is that after a little while (10 minutes, sometimes less?) the keyboard and trackpad on my mouse become non-responsive (as does my Bluetooth keyboard; the USB mouse continues to respond).  At that point I'm hosed and have to hard-reset the Mac.
This DOES NOT happen when I uninstall the VZAccess Manager, so that certainly points to it as the culprit.
Any thoughts?
Thanks,

Based on the information you  provided, the radio signals may be conflicting or there maybe issues with the ports that are being used.   
If the signals are conflicting you can try using a different port, using  wired devices, or moving the wireless devices away from each other. 
Also try these steps below:
Update your Mac at http://www.info.apple.com/kbnum/n106704 to Mac OS X 10.4.6 or later, if you haven't already done so.
Install the Apple Keyboard Update 1.0  at http://www.apple.com/support/downloads/applekeyboardupdate10.html using Software Update http://www.info.apple.com/kbnum/n106704 or by downloading it from the link above.
If you've updated to Mac OS X 10.4.7  or later, you DO NOT need the Apple Keyboard Update 1.0.  (If the keyboard or mouse becomes unresponsive, you may be able to unplug it and plug it back in to restore functionality until any needed updates have been installed.) 
If you have tried both these steps and the issue still occurs, try the Mac support page at the link below.
