USB Troubleshooting on
Microsoft Windows 98, Me and XP

Most USB devices require USB device software drivers be installed before connecting the USB device to the computer. When installing a USB device always follow the documentation from the USB device manufacturer.

USB devices are detected by the computer but are not working properly.

• Right-click the My Computer icon and select Properties
• Click the Device Manager tab and open Universal Serial Bus Controllers by clicking the plus sign (+). One of the following four conditions are displayed

1. If the device displays in Device Manager, the USB port is working properly. There is a physical problem with the device or there is an issue with the device software drivers. Try disconnecting the USB device, closing any software for the device that may be open, uninstalling the USB device software driver, and then reinstalling the driver. Connect the USB device to the computer after the software drivers are installed. Refer to the device manufacturer for more information.

2. If the device displays as an unknown device, check the following items:
   • If the USB device is connected to a USB port on a port replicator, unplug it and plug it into a USB port on the notebook.

   • The device may not be getting enough power.
     If other USB devices are connected to the system, remove all other USB devices (except keyboard and mouse) and restart the computer. Check Device Manager again. If this solves the issue, use a powered USB hub to power more devices.

   • Disconnect the USB device, close any software for the device that may be open, uninstall the USB device software driver, and then reinstall the device software driver.

3. If the device displays under Other Devices the USB ports are working but the device software drivers need to be installed. Unplug the USB device and install the software drivers.

4. The device is not listed at all.

USB device not detected by the computer.
Perform the following steps to troubleshoot the USB port when the computer does not detect a USB device:

1. Check Device manager to see whether the device displays under the USB section or the Other Devices section. To do this, follow the procedures below:
   
   • Right-click My Computer, and click Properties
   • Double-click the System icon, and then click the Device Manager tab.

      In Windows XP, click Start, click Search, and then click all Files and Folders.
      

   8. Set the Look in box to Local Hard (C:;D:).

   9. In the Named box type "usb.inf", then click Find Now.

   10. Right-click USB, then Install.

   11. Restart the computer and verify that the USB Root HUB exists in Device Manager.

   12. Install the device software driver using the manufacturer's recommended method.

   13. Reconnect the USB device.
       Consult the manufacturer of the device for support if the device still fails to display.

Error message: Activation failure of BIOS USB.
Check the Basic Input/Output System (BIOS) for Legacy USB Support.
To do this, follow the procedures below:

High Speed USB controller availability
http://www.faqfarm.com/Computer/Hardware/36532
For the most part, the High Speed USB controller will be integrated right onto the motherboard of your system. You will sometimes run into this problem when upgrading to or installing a new version of XP, for sometimes it does not readily have the drivers available.

What you have to do is to actually find out the motherboard that you have in your system, and download, or request the CD, that has the motherboard resources on it, in order to get Windows to install that particular controller.

If you have a name brand computer, you should be able to contact the manufacturer to get the CD or download. However, if you have built the system, or someone else has built you the system, you will need the CD that came with the motherboard.

Hi-Speed USB Device Plugged into
non Hi Speed USB Hub

This message will appear if a higher version USB device (i.e. 2.0) is connected to lower version ( i.e. 1.0) USB port. It will further specify that a High Speed USB Host Controller must be on the computer. This is a driver.

A Compaq Presario 725CA (2002 notebook) has USB 1.0 ports. If you try to connect a USB 2.0 device to a USB 1.0/1.1 port, this message will appear.

This issue cannot be resolved by installing a driver.
If you like to use your USB Mini-Drive effectively with your Presario notebook, then you need to add a USB 2.0 port to your Presario.

Presario 725CA has a Type II PC Card slot with support for 32-bit CardBus for expansion. If you have not installed any card in this slot, then you can purchase a USB 2.0 PCMCIA card and install it in this slot.

Cost (2005) of a USB 2.0 PCMCIA card ranges from US $32.00 to $79.00
EXAMPLE: D-Link 2-Port USB 2.0 CardBus Adapter (DUB-C2)
This card is designed to work with mice, keyboards, external CD-R/RW's, external hard drives, PC cameras, and all other USB enabled devices. It is 40 times faster than previous USB (1.0) adapters and 20% faster than Firewire (IEEE-1394). Each of the two USB 2.0 ports transfers data at 480 Mbps (Megabits per second), making it ideal for external storage, backup, networking and digital video.

The DUB-C2 is compatible with USB 2.0 standards and is backward compatible with USB 1.0 and USB 1.1 products. This gives you the ability to connect all of your USB 1.x devices to the DUB-C2 USB 2.0 adapter and they will work. Each port detects whether the connected device is USB 1.x or USB 2.0 and automatically runs the device at the correct speed.

The DUB-C2 supports Plug-and-Play installation which makes the DUB-C2 easy to install.

Incompatible USB Terminals:

1. An absence of USB sockets is a problem on some older computers and this does not enable connection of USB devices. One solution is to add a
   USB Internal at motherboard adapter 2-port
   USA $3.99 (2005-01-13) from Cablestogo.com
   The USB adapter installs in any empty PC slot
   Cable length: 200mm (around 8 inches)
   Connectors: Two 5-pin Headers to Dual series A ports
   Adds Dual USB Ports to AT Motherboards with 10-pin Header
   
   

2. Recessed USB sockets in a vertical placement may be on some older laptops, such as the Compaq Presario 725CA, to save space. This placement will NOT afford adequate clearance for the connection of a USB Mini-Drive, or similar device, whose housing butts against the computer housing and holds the USB male terminal on the accessory from adequate or any connection with the computer female socket. One solution is to use an extension USB cable, NOT a jump shot cable.
   1m USB A/A (male/female) EXTENSION CABLE
   USA $6.99 (2005-01-13) from Cablestogo.com
   Foil and braid shielding reduces EMI/RFI interference and twisted-pair construction helps reduce crosstalk thus ensuring high-speed, error-free data transfer.
   
   

3. USB 1.0 Sockets for USB 2.0 devices.
   Some USB 2.0 devices will operate, yet at a greatly reduced speed of data transfer, through a USB 1.0 port. Others may fail completely. One solution is this:
   A Type II PC Card slot with support for 32-bit CardBus for expansion may be present on the computer. If you have not installed any card in this slot, then you can purchase a USB 2.0 PCMCIA card and install it in this slot.
