I recently bought an internal memory card reader that has a USB connection. I have a USB port (built in on my pc case) which i connect to F_USB 1 of the motherboard. So, i connected my card reader to F_USB 2 of the motherboard. The problem starts, my card reader works, it is able to read memory cards, but it can't detect any USB 2.0 devices such as pendrive (it has 1 USB port).
More worst, my USB port on the PC case can't even be recognized. I tried plugging in my external HDD or Pendrive, it came up with a message "Usb not recognized". So, I tried removing memory card reader and the USB port works again. Or, I removed the USB port and the card reader works. Why is this happening? Not enough power? BIOS not set to run 2 usb? Mobo failure? or my card reader has problem?? Please help! much appreciated.
