As I have a lack of USB ports on my laptop, I installed a PCMCIA USB cardbus a couple of months ago. Ever since I installed the card, it has been giving me problems. The cardbus can recognise the device but everytime when I insert my USB device(particularly thumbdrives) into the cardbus, it would freeze my laptop for about 15 to 20 seconds and data transfer speed are extremely slow compared to the USB ports intergrated on the laptop itself. It would take about 2mins to transfer a 3MB music file using the cardbus compared to the intergrated USB ports which took only a mere second. Sometimes my USB drives would keep disconnecting and reconnecting itself. I have also checked with the device manager which stated that it was working properly.

Now can anyone tell me what to do? I only have two USB ports on my laptop and I can't afford to use any of them as one is for modem and the other a mouse. I have also used a USB hub before, which as well gives just about the same problem as the PCMCIA cardbus.

Thanks.
