Hi, I would really appreciate if anyone could help me with this:
I have a PC with Win XP Home and a printer connected to one of two serial ports on PCI serial port card (Kouwell Multi I/O 222N-2), printing is no problem but whenever I do something with the printer (open cover, turn off, turn on, disconnect the cable from PC), windows slow down so much that the only solution is turning PC off...When I open the task manager and then eg. open the printer cover, I can see winlogon.exe CPU usage rises to 99%.
I tried installing Win XP Pro but the problem is exactly the same, I tried to put the PCI serial port card to another PC with XP and different mainboard but again with the same result, I tried installing the card driver from other source than from the original CD, same result, I tried other piece of the same card type, still the same... Also it is not a problem of the printer, basically anything that I connect to these serial ports brings the same problem.
If I do any of these things on COM1 port which is directly on mainboard, there is no problem at all...
I have been searching for a solution to this problem on the net but found nothing, so I will be really grateful for any thoughts...
