My Dell Inspiron 8200 recognizes an NEC 2-port USB 2.0 Cardus Card in the PCMCIA slot but as soon as I connect an iPod Touch or a Garmin GPS device, my laptop locks up, i.e., I can't move the cursor using either trackpad or mouse and the activity light stops blinking but remains on. The computer returns to normal when I pull out the card. I can use the ports on the card to print but that's all. Dell technical support "thinks" that the problem is inherent in the computer's architecture, that it can't handle those devices power requirements. Could they be right? Is there anything I can do to solve this problem?
