I have bought a USB pcmcia cardbus. I hav downloaded the drivers and the computer rcognises it. When I put in any USB device, nothing happens. In the maual it says that the power supply i running at 100Ma for each port. It came with a USB power cable, but I am unable to use my computers original USB port as my nephew has buggered that one up for me. I am ble to use a 5v adapter in place of the USB power. Which in the manual says that each port will run at 500Ma. What is Ma. Will my USB devices work with 500Ma power.

500mA it will be, that's MILLI AMPS; or 1/2 amp
Try connecting a USB device to the card, THEN plugging the adapter in.
If it STILL doesn't see USB devices contact seller, you MAY have a faulty device
