Hey guys.. I'm having a problem.. I have 4 USB ports and windows doesn't
read any of them. Anytime something is plugged in, i get the "USB Device
Not Recognized" error. However, when I plug my phone via USB, my laptop
charges my phone, but doesn't read it. I've tried everything.. updating
the bios, delete infcache.1, I tried soldering the usb ports again, I've
tried all of that. I've searched the web and I can't find any
solutions.. I'm running Windows Vista Home Premium on a Toshiba
Satellite A135-S2376. Also, none of the posts on here have helped me.
Can someone shed some light on my problem?

Have you gone into the Device Manager and uninstalled all of your Host
controllers and let the system reinstall them?

I and many others have experienced corruption of the basic USB drivers
following OS updates or service packs.

If uninstalling the USB drivers in Control Panel and then rebooting does not
solve your problem then something has failed on the laptop motherboard.

If the machine is out of warranty it is probably a wiser use of money to
purchase a new laptop than to try and have it repaired.

This worked on me after installing all updates including SP2.
Unplug/remove all devices from their ports (usb, etc.), shutdown your
laptop, pull out the battery and then hold down the power button for 1
minute. Then replace the battery, turn on the laptop and plug back in
devices in reverse order. It worked for me great without me having to
reinstall the logitech drivers for my V220 mouse. Even though I am a 12
yr technician and A+, this really threw me for a loop! Hope this works
for you!

You can go to manufacturer's website of the device and download &
Install the drivers / software for that device.

If your device is not faulty then plug your device in your PC and go to
the device manager then update your 'Flash Drive'
([url]http://www.eprovided.com/usb-flash-drive-data-recovery.html[/url]). You can
do this to get there.
Go to START -RUN-Type in devmgmt.msc

Look for YELLOW MARKER(s)
Right Click where the yellow represents and choose UNINSTALL
Choose YES - when asked if your are sure

Restart your PC

Allow the found new hardware wizard to Reinstall your USB Driver.
If you are still encountering problems then you can consult the
experts. They can help you a lot with 'Data Recovery'
([url]http://www.eprovided.com[/url]) and USB Drive malfunction.

It could be problem with the your USB port. First of all you have to try
with rear side port if not solved then you have to installed chipset
driver again.
