Update the USB EV2300 Drivers for Windows 98SE

If you previously installed drivers on this machine, windows will automatically reinstall the old drivers unless the old drivers are manually uninstalled.
Please read the entire page before proceeding with the update process.

Follow the steps below to update the drivers.
  1. First uninstall the device.
  2. Then follow the new driver installation steps to install the new driver.
    Note: If the "New Hardware Found" wizard automatically installs one or both drivers then you will have to follow these special steps after uninstalling the drivers.
    Follow the new driver installation steps after performing the special uninstall steps.
The uninstall/reinstall process has to be performed for each USB port - this includes ports on a connected hub. The port being uninstalled is the port to which the EV2300 is connected at the time of uninstall. For persons familiar with the Windows 98 SE registry tools it would be easier to go the advanced user way as mentioned below in Additional information 4.

Additional information:
This information is provided for advanced users of Windows 98SE only.
  1. The EV2300 USB board ships with 2 drivers.
    The "TI USB Firmware updater" driver is used during the boot up process of the EV2300.
    The "TI USB bq80xx Driver" is used by the end application.
  2. The "TI USB Firmware updater" driver lifetime is only a few milliseconds, therefore it does not show up in Device Manager unless it is improperly installed.
  3. Since uninstalling the "TI USB Firmware updater" is difficult, it is recommended that the uninstall and install steps be performed instead of the "Update Driver" from Device Manager.
  4. Advanced user uninstall
    If you connected the EV2300 through a USB hub at any time in the past and want to update the drivers, an easier method would be to open "regedit.exe" from the command line or Start Menu->Run and delete the following registry keys along with its subkeys.
    HKEY_LOCAL_MACHINE\Enum\USB\VID_0451&PID_2136
    HKEY_LOCAL_MACHINE\Enum\USB\VID_0451&PID_0035
    Then run cleanup.bat(step 8 of uninstall)
    Then follow the special uninstall steps.
    This will uninstall the driver for all ports and will save time compared to the uninstall process for each port. This method is also more reliable because it does not depend on the hubs that were plugged in, instead it just erases the entire history of ports to which the EV2300 was previously connected.
  5. Important note: The registry is used by Windows to store information. Some changes to the registry may prevent Windows from booting or may cause programs to malfunction.
    Please be careful to only delete the above mentioned key and its subkeys, do not change or delete information in any other registry location.
