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.
I have the same problem with my LG VX 5600. In fact I've had this problem with my past 3 phones. Could someone please fix the VZAccess Manager?
