XP COM Port problem.

I had a working Windows XP system using an IOGear GUC232A USB PDA/Serial Adapter to connect my HP palmtop and synchronize with ActivSync using COM5. I also have a CyberPower UPS that uses COM1.

Yesterday, I disconnected the COM1 cable and plugged in a cable for a LEGO Spybotics robot. This brought crashed my system (probably the power management COM1 sensitivity). So, I restored the original cable.

Now, I can no longer communicate on COM5. I've tried reinstalling the ActivSync software and the IOGEAR driver (can't seem to find it on my IOGear CD). The driver it is looking for is "ATEN USB to Serial Bridge."

When I ran the IRQ summary, there is no allocation for COM5 which I understand should be IRQ 3 or 4. COM1 is IRQ 4.

Any suggestions appreciated.

Thanks,

Chuck

I had a situation similar to this with a user disconnecting his palm from com1 and plugging something else..  There was static in the device, and it burned the com port from the computer... after this, We had to change the motherboard. Fortunatly, it was under warranty.... They technician told me this was a problem with some dell Desktops..

I believe that nothing is burned out. It is the USB to serial setup that stopped working even though the cable was the UPS serial cable that went directly to the serial port on the computer. When I re-attached the cable it accepted it fine. However, the USB to serial still doesn't work.

I have finally managed to get ActivSync working with my palmtop again. It took re-installing the driver...forcing the driver used. Then re-installing ActiveSync. I thought I had done this before, but apparently not.
Please close this item.
Thanks,
