Simmtronics Pendrive problem

when I plug in my new Simmtronics pendrive 128 mb the computer shows a blue screen with following message:

File Name USBD(01)+0000094F

Error:OE:0028:FI052B2F

I need to reboot after removing the pendrive to get the PC to work.

The pendrive works perfectly well on other computers

Windows ME dosen't support a lot of hardware you must check your hardware compatibility list HCL

SUMMARY

This article describes general troubleshooting tips for Universal Serial Bus (USB) devices in Windows 98, Windows 98 Second Edition, and Windows Millennium Edition (Me)

MORE INFORMATION

Because USB devices are Plug and Play devices, there is little that you can do to control or configure them However, most you can trace most USB problems to one of the following conditions: • Malfunctioning or incorrectly configured hardware

• Malfunctioning, incorrectly configured, or missing device driver

• Mismatched cabling

• Out-of-date firmware or basic input/output system (BIOS)

• Improperly configured root hub

You can use the following troubleshooting tips to check for each of these conditions to help you resolve USB device issues

Malfunctioning or Incorrectly Configured Hardware

Typically, if you plug a malfunctioning or incorrectly-configured device into a USB port, it causes the computer to stop responding (hang) In the majority of these instances, you must physically turn off the computer and turn it back on to reset the bus Note that it may be more difficult to identify which device is malfunctioning or is incorrectly configured If another computer that you know is working correctly is available, try to plug the device into that computer to see if you encounter the same issue

If the device is plugged into a secondary hub, unplug the device from the hub and then plug the device directly into the root hub.

Many hardware problems (such as high or low power, bandwidth shortage, malfunctioning or incorrectly configured firmware, and so on) can cause issues to occur.

Check Device Manager to be certain that the root hub is functioning correctly If the root hub is displayed with an exclamation point in a yellow circle, verify that the BIOS is assigning an interrupt request (IRQ) to the root USB controller This is required for the device driver to be loaded For additional information about how to use Device Manager to troubleshoot hardware issues, click the article number below to view the article in the Microsoft Knowledge Base:

If no devices work when you plug the devices into the root hub, verify that the power requirements of the bus are not being exceeded USB devices can draw a maximum of 500 milliamps for each connection If a device attempts to draw more power than this, the specification recommends that the computer be able to disable that specific port until the computer power is cycled (this is called "suspending" the port) In addition, if the device draws less than 50 milliamps, the port never becomes active

Check the Power tab in USB Root Hub properties to check the power usage of the USB bus

Malfunctioning, Incorrectly Configured, or Missing Device Driver

When you plug in a USB device, the computer should load and then configure the device without ever requesting a device driver (assuming that the device falls within the defined and supplied class drivers) If the computer prompts you for a device driver, check with the manufacturer of the device to determine if a driver is available

Mismatched Cabling

There are two types of USB cables, high speed and low speed Low-speed cables differ from high-speed cables primarily in their shielding If you plug a high-speed device into a low-speed cable, you can cause signal distortion over long distances.

Verify the entire USB chain is working correctly to be certain that a device that requires the ability to draw power from the hub is not plugged into the chain on the other side of a non-powered hub This causes that hub and all of the devices down the chain to be suspended If the hub is a powered hub, verify that the power supply for that hub is configured properly

Out-of-Date Firmware or BIOS

The key to all USB devices is the firmware The USB device's firmware contains all of the information about the device A port is not reset until all of the descriptors in the firmware have been loaded and verified by the root hub This is critical because it applies to items such as printers and modems Make certain that you have the most up-to-date firmware that is available for both your computer's BIOS and each individual device

The symptoms of malfunctioning or incorrectly configured firmware might be unusual Typically, when you remove and then re-add a USB device, the device simply becomes available again However, the device may appear as a second instance of that device, and load itself as such in Device Manager If you see duplicates of a device, verify that you have the most up-to-date firmware for that device This issue is common with USB printers and modems A similar issue that has the same cause occurs when a device loads a device driver and then adds a second device for which there appears to be no driver The second device is displayed with an exclamation point in a yellow circle in Device Manager The device may work correctly, but you cannot remove the "ghost" device until you unplug the parent device that seems to have generated the ghost device Also, you may be able to resolve this issue by updating the firmware or the device driver for that device

Incorrectly Configured Root Hub

USB controllers require that an IRQ be assigned The IRQ line is assigned in the computer's BIOS, and usually IRQ 9 is assigned
