Question about PC Desktops

1 Answer

I have a Toshiba Equium a100 that wouldn't recognise any usb2 devices. So i deleted all the usb controllers and hubs etc, downloaded the uptodate chipset drivers from Intel and expected the computer to recognise that it needed drivers for USB but I just have the dreaded yellow markers in device manager. Any simple ideas to get the USB working again?

My usb ports are not recognizing any devices such as my iphone, ipod, etc. I have a dell dimension 4700 runnning win xp sp3


It seems that many people are still getting the 'USB Device not Recognized' problem from time to time. Unfortunately there is no easy fix.

Firstly, it's recommended that you make sure every one of your motherboard drivers are completely up-to-date, but you probably already knew that.

In XP, after a USB port isn't used for a long while the USB driver built into the OS sets the OHCI controller to suspend. When you plug a device back in, it can sometimes fail to 'wake up' properly. This problem was supposedly fixed in SP1 but there is a related registry hack that may still be able to help.

Run regedt32.exe and navigate to;

HKEY_LOCAL_Machine\SYSTEM\CurrentControlSet\Services\Usb

Create the Usb key if it doesn't already exist. Under this key, create a new DWORD value called DisableSelectiveSuspend and give it a value of 1. Then restart the PC.

A long shot perhaps, but I recall having similar problems with a USB hub built into my Microsoft keyboard and adding this key seemed to solve it. It wouldn't hurt in trying icon_smile.png.

Alternatively, removing all entries relating to USB in Device Manager and all associated USB drivers will force XP into refreshing the USB driver stack.

Begin by unplugging all USB devices, then use Add/Remove Programs in Control Panel to uninstall any USB driver software. Next, boot up into safe mode and go to Device Manager. Once in device manager make sure 'Show hidden devices' is checked under the View menu. Uninstall all device entries in this order;

1. USB peripheral devices (printers etc.)

2. HID and/or Composite USB (Human Interface Devices) You're using PS/2 input devices so you may not have this entry.

3. USB Root Hub(s)

4. USB Host Controller(s) (Universal or Enhanced Host Controllers)

Then boot back into Windows (not safe mode) and it should populate the Root Hubs & Host controllers again. Proceed to plug your USB devices back in, starting with your powered hub. Be aware that most USB printers and scanners need to have their drivers installed first before you plug them in.

High speed usb port toshiba a100 331 which usb port is the high speed port for webcam


Shouldn't matter so long as your computer uses usb 2.0. If it is using or only capable of 1.1 then you just might want to consider a new computer. But to tell you the truth never noticed much difference between 2.0 and 1.1 on a webcam. Hope this helps
