Question about NEC USB 2.0 ( ) Laptop PCMCIA CardBus PC Card Adapter (USBP2D20) Serial Adapter
I've been trying to use the above device in my Dell Inspiron 8200's PCMCIA slot with an iPod Touch. I'm running XP Pro SP2. I can print from one of the ports but when I connect the Touch or a Garmin Nuvi, my computer locks up. Removing the Touch or Nuvi doesn't unlock the computer. To do that I have to pull out the card. Then everything is Ok. Dell phone support thinks there's a power problem. I refuse to give up. Is there anything I can do to resolve the matter. I just ran event viewer and found a number of warnings and a couple of errors. I need the advice of a master.
Your problem is a power overload on the USB 2.0 card. If you plug in a 5volt power supply to the USB 2.0 PCM/CIA card, it will solve your problem. You can also use any USB port on your computer to plug in an A-A USB cable to power the PCM/CIA card and it should resolve the lockup. Also, check and make sure you have enough RAM memory in your comptuer for Windows XP. Recommend 512, but runs much better on 1024 (1 gig) of RAM.

Thanks for your suggestions. I tried each of them along the way without success. Then a Best Buy Geek Squad member, after failing at everything else, tried connecting my iPod Touch to the native USB 1.1 ports at the back of my laptop and it worked even though Apple claims USB 2 is absolutely necessary. It worked. Perhaps MS's SP2 juices the native ports. I have no other explanation.

I'm no master, but...
Try supplying external power to the USB card (it should have a power-in connector), possibly from a non-PCMCIA usb slot or from a ps/2 keyboard connector. See elsewhere for how; i've never done it myself.
You may need to update the USB drivers, see http://support.microsoft.com/?kbid=873169
