I bought a sansa clip and plugged it in. It won’t show up on “my computer” and I am not sure it is charging while in the USB port on the front of my computer.
Try a different USB port. The ones in the back of a desktop usually put out more ‘horsepower’ than the front ones. Also try switching to MSC mode in Settings > System Settings > Usb mode on your Clip. Then it will be seen as a ‘dumb’ flash drive or memory stick.
The battery icon on the screen should flash if it is accepting a charge. Leave it in for a good 3 - 4 hours for the first time. You can also use an AC - USB charger. Some cell phone chargers will suffice as well.
