Windows 7 fails to recognize all USB

[wisdommoney]

Hi,
I just have HP i5 mother board replaced by manufacture. Apparently it does recognizes my external hard drives (3 units).
it makes sound when I plug them on or unplug, the hard drives picture or icon were not registering on my screen on "my computer". it does recognizes the flash drives with no problem.

Hi,

Plug it in and look in device manager and see what you get there.

Most likely you have a few device with yellow exclamation mark witch means missing driver for them.

Do you have the same problem for other usb device ?

maybe you need to install driver chipset or usb driver.
