Update the USB EV2300 Drivers
for Windows 2000 / XP
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.
- Connect the EV2300 to a USB port.
- Run SETUP.EXE and earlier steps as specified in first time
installation instructions.
- You will see some dialogs mentioned in the first time
installation instructions. Follow the same instructions for those steps.
- Perform these steps for each USB port on the computer. If you use
a USB hub to connect the EV2300 you will have to do this for each port
on the hub also.
This upgrade 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 XP / 2000 registry tools it would be
easier to uninstall using the advanced user way as mentioned below in Additional
information 4 and then do a fresh install.
Additional information:
This information is provided for advanced users of Windows XP / 2000
only.
- 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.
- 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.
- 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.
- 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
If the registry keys cannot be deleted, please right click and select
"Permissions...", give "Everyone" full access and then delete. You will
need administrator rights to perform this step.
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.
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.
