I have a strange problem. My internal card reader won't read a card until I unplug the reader from the motherboard usb port, and then plug it back in. However, the USB port on the card reader always works. It's just with other flash media, like an SD card.
If that didn't make sense, here's more detail. I plug an SD card into the reader while the computer if off. I turn computer on. The card cannot be read (and the green indicator light does not go on). I unplug card reader from motherboard, and plug it back in. SD card can be read (and green light goes on).
There is also a red indicator light showing which is always on, so the reader always has power. Hence the usability of the USB port on the reader.
Any ideas? Could it be a mainboard issue rather than a reader issue?
