chrisNova777: What are you trying to do with the serial ports that does not work? I mean, how have you tested if they are broken or not? Does a serial mouse work, or have you tried a loopback test with a terminal program?

The thing is, the dongle might be too power hungry compared to a serial mouse and draw too much current from that RS232 level converter that is on the motherboard, it's a charge-pump based voltage doubler/inverter.

What dongle is it?

It maybe was incompatible levels and damaged the winbond?

Also the auth of that age seems reversible...
