need some help please, i installed a 4 port usb card into a 686 mx machine. Now i get this error message.
Error writing to USBPN01 for printer canon s200sp Invalid access to memory location"

It will however, work but will stop halfway through.
any suggestions please.

Has the USB 4 port card installed correctly? (no errors in the devices list)
Do you have another USB port to test the printer in? (most motherboards have onboard USB ports)
Is the printer installed correctly?

I am assuming the USB card is the only new hardware added to your pc recemtly & I dont know what OS you have.

thks all, i reinstalled the drivers. It appears to have settled things.

Great.. pleased to hear all is well again!
