USB no longer reads

[lb77]

hi

 

my pc has usb ports at the back and 1 at the front, my usb port at the front of the pc no longer reads it still powers up but wont acknowledge a device. (i know this because my card reader light comes on but will not show cards slots as drive g,h etc..) when i plug the card reader in usb port at back it recognise it and same with my memory stick)

 

this problem started when i plugged in my usb convertor so i can use playstation joypad to play snes emulator. i have used this many times and never had problem.

 

but the other day when i plugged this in i got message "new device etc... not installed correctly)

 

since then the usb port has not been working properly (yet it can still power a device)

 

i looked in device manager under USB bus controller no problem there.

 

i did alittle research and turned off pc and unplugged power and this still has not fixed my problem.

 

any suggestions?

Hi, and welcome to Extreme Tech Support - Free PC Help.

First one that comes to mind may just be connections, have a good look in the port itself to make sure the connector leafs haven't been bent or broken. Second one is to turn off the power, remove the cover, you will then see the cables from that front port and where they plug into the mother board, check they haven't become loose on the motherboard, remove the plug and replace to be sure.

USB devices ALL draw power from a specific rail on the PSU (power supply)

make sure that no other USB devices are plugged into the back ports when trying to use the front ones
