Communication Manager Timing Out Causing Laptop to Freeze (Event ID 256)
I just recently purchased USBConnect 881 card and installed it on my Windows XP Pro (SP2) laptop. Within 5 minutes of my reboot after the install, my computer locked up indefinitely. I rebooted and tried again, and had the same result. I disabled the AT&T Communications Manager and turned off the function to auto-start as well as the 'make this my default wireless manager' option, and my laptop came back to life again without freezing. That is, of course, until I tried to use the Connect card again and about 10 minutes after using the Communications Manager the same 'freezing' occured.
In my Event Manager, I get several entries with the following descrption:
Event ID: 256 Type: Warning Source: PlugPlayManager Timed out sending notification of device interface change to window of "C:\Program Files\AT&T\Communication Manager\ATTCM.exe"
There is also one entry with this:
Event ID: 256 Type: Warning Source: PlugPlayManager Timed out sending notification of device interface change to window of "ModemDeviceChange"
I haven't been able to successfully use the Connect card without a system freeze + reboot to this point. It works great during that 10 minute period though.

Is there a support forum or number to call for issues like this? I doesn't look like anyone has any idea how to fix this, and the freezing is making the Connect card useless. At this point, I think the easiest thing is to return it within the 30 day period and try one of the other service providers out.
