Topic # 101871 10-May-2012 19:03 Send private message

Hi guys,

I'm running XP Home on a Dell Dimension 2400.  Recently the two USB ports on the front of the box have stopped accepting anything i plug into them - Windows says its an unknown device.

The four ports on the back of the box continue to work well, and any device that fails on the front ports works perferctly on the rear ones!!

evice Manager claims it can't find a better driver anywhere; I've disabled / re-enabled; unistalled / reinstalled. Nothing seems to help.

Any suggestions?

Do you by any chance have a sony ericsson phone, or have had one in the past? 
The reason I ask, is because there is a Sony Ericsson driver that gets put in the system 32 folder in c:\windows that can play havoc with USB. 

If you do, delete a file called seehcri.sys and then reboot, then go into device manager and USB Root Hub and update the drivers.

sounds to like either the ports are dirty and need a clean or they've just worn out (not connecting properly)

how happy are to play around on the inside of your PC

if to do so can you grab an add in usb bracket like this


and plug it into the same connector that the front USB ports are and see if that makes a difference if it does then the ports a worn out or dirty if cleaning them doesn't fix it then replacing them is the only option

  • Hi, hopfully you are not using a usb mouse if you are may want to find a PS2 mouse turn your computer off plug it in and boot it again just for this part
  • long shot but try going into device manager and expand universal serial bus controllers. right click and unisntall everything listed under it. then reboot the pc let the controllers reinstall and see how you get on. post back so we know if its fixed it.

thanks




Hu? did i do that?
