I am using xp professional sp 3. Motherboard is gigabyte 8ipe1000g

Back 4 usb, front 2 usb. I dont use too much front usbs and i dont know if i connected correctly but i only charge my mobile and sometimes file transfer, and no problem.

For back usbs, i use webcam keyboard and external harddrive but always they give errors.

10 minutes ago , i could see webcam, harddrive in my computer. Now they disapperared. In device manager, there are 2 unknown device. If i take off and put another place, it can work. I tried a lot of times and sometimes it became succssfull.

While external harddrive was working, it was saying "writing was unsucsesfful and had delay."


How do i understand if drivers are defected or motherboard or my devices but i dont think my devices are defected.

 

 

This was yersterday.

 

Today:

 

i installed  lan, chipset and audio drivers  1 month ago.

Now it shows logicech webcam but can not recognize ext harddisk and says "can not recognize because one of usb s are not working." When i click device manager, it shows unknown device.

Also at front usb same. Can not show my phone but my phone is charging. And same error, recognize. I can not understand why unworking usb changes sometime sfront, sometimes back

@ Cursed Chico:

 

Read and try to apply this Microsoft KB Article using their Fix it Wizard first:

http://support.microsoft.com/kb/925196/en-US

 

If that doesn't work, or you get hung up, you can Publish a Snapshot of your entire system in this forum using Speccy:

 

http://www.bleepingcomputer.com/forums/topic323892.html/page__p__1797792#entry1797792

 

Post the link of the snapshot in your next post. Someone else in the BC Community will read it and advise because your USB issue is def a registry entry problem and I am not qualified to show you how and where to correct such entry(s).

 

Be patient and wait for the real BC wizards to show up in this post and lend the solution you need.

I suggest that you go back into 'Device Manager' and expand the entry 'Universal Serial Bus Controllers', then double click on each controller in turn and delete their drivers. Then re-boot the computer. This will automatically re-install the drivers.

 

Note that this will almost certainly disable your mouse. To turn the computer off, press on the 'Windows' key on your keyboard, this brings up the 'Start Menu' and you can select 'Shutdown' with the 'TAB' key ( this is the one on most keyboards that has two flat arrows in opposite directions, and usually 4th key up on the extreme left hand side. Sorry for the vagueness, but I am not familiar with Turkish keyboards.) Press the TAB key slowly and you will see 'Shut down' selected when it has a sort of dotted line around it, then press the 'Enter' key. You can then use the TAB key or the arrow keys to select either shut down or re-start. When it starts up again, you will have your mouse back.

 

If this works, great, if it doesn't, post back.

Please download MiniToolBox, and save it to your desktop and run it, and checkmark the following checkboxes:
  • List last 10 Event Viewer log
  • List Installed Programs
  • List Users, Partitions and Memory size.
Click Go and post the result (Result.txt). A copy of Result.txt will be saved in the same directory the tool is run.
Note: When using "Reset FF Proxy Settings" option Firefox should be closed.
