FAQ for Installation of USB EV2300 Drivers for Windows 2000 / Windows XP
Q. I got a "File not found error" while following the instructions for first time installation. Am I missing some files?
A. You may be missing files if you did not copy them properly or did not unzip all of them to the directory from which you are attempting to install.
There should be a total of 5 files : 2 files with extension .inf, 2 files with extension .sys and 1 file with extension .bin
If you have all these files in the directory from which you are attempting to install, then the error may be because

- The proper local folder was not specified.
- The installation files are corrupted due to improper unzip/copy.
- You did not reboot in the beginning after copying the driver installation file.

The proper action to take for this error is to Cancel the installation, Reboot and follow the update driver steps.
If a file cannot be found then press "Cancel" to Cancel the installation.
Do NOT choose "Skip File" in any case.
Q. Windows does not show me the extensions of any file. How do i view it?
A. In Windows Explorer select the "Folder Options" under the "View" or "Tools" Menu. This will open an options window. Select the "View" tab from the top of that window. Then uncheck the "Hide extensions for known file types" options.
Q. Windows does not show me the .sys file. It does not even show it in the source provided to me!
A. In Windows Explorer select the "Folder Options" under the "Tools" Menu. This will open an options window. Select the "View" tab from the top of that window. Check the "Show Hidden files and Folders" option.
Q. What procedures do you recommend to avoid problems?
A. Please see the recommended procedures section.
Q. Does the EV2300 USB board use two drivers on Windows XP / Windows 2000?
A. Yes. The first driver "TI USB Firmware Updater" has a typical life of a few milliseconds if it is working properly, therefore it is very difficult to uninstall using conventional uninstall driver methods. The second driver "TI USB bq80xx Driver" is the driver that is visible and used for communication with the application software.
Q. I followed all the driver uninstall and install steps but my application does not seem to communicate with the EV2300. What should i do?
A. Firstly make sure that the EV2300 is connected. Go to Device Manager and make sure that "TI USB bq80xx Driver" is present under the Universal Serial Bus controller. If it is not present then it means that the drivers were not installed properly. Please uninstall and reinstall.
If it is present then check its properties. It should say that the device is working properly. If not then uninstall and reinstall.
If the device is working properly then make sure that you have a target device connected to the EV2300 and that the target matches the what the application expects. Make sure that only one instance of the application is run. If multiple instances of the application were running at any point, then reboot and try again.
Disconnect the EV2300, wait 5 seconds, reconnect and test. Reset the target and test. If all the above fail then Contact the application software provider.
Q.I followed all the driver uninstall and install steps but Device Manager reports that "TI USB bq80xx Driver" is NOT working properly.
A. Make sure that you followed all the steps in the Uninstall/Install. Do the Special Uninstall steps after uninstalling, then try the installation again. If you still have problems, then you may contact the vendor who provided you with the software or Texas Instruments Customer Support Center/Marketing team.
Q. I am using Windows XP with a service pack greater than SP1 and I am having problems. What should I do?
A. Please bring this to the attention of Texas Instruments. There may already be a fix for the problem or Texas Instruments will begin working on the fix if you report the problem. Please provide a detailed description of how to duplicate the problem and the OS/hardware and configuration that you are running the driver on.
Q. The EV2300 works properly only on one USB port. It does not work ( properly ) on other USB ports.
A. You may have had old drivers in the past and forgotten to update each port. The port that was updated works properly and the port that was not updated does not work. Consider using the Advanced user method in the Update Document to avoid problems with other/newer ports.
Q. The EV2300 is connected through a hub and it does not work ( properly ). The EV2300 causes Windows to crash sometimes when it is connected through a USB hub.
A. The Windows driver was not tested with a USB hub between the EV2300 and the PC. Please see the recommended procedures document. If you have problems, the only solution is to connect the EV2300 directly. Please report the problem to Texas Instruments with details.
Q. I installed some drivers and now whenever I plug in the EV2300, my computer hangs.
A. This problem is seen when incorrect drivers are installed(usually drivers that are not meant for the EV2300). It is very difficult to get into this situation because Windows prevents such attempts. The only recourse is to perform the special and advanced user uninstall and then follow the install directions for the EV2300 drivers.
Q. Windows does not allow me to stop the device from "Safely remove Hardware". The error shown is "The device 'TI USB bq80xx Driver' cannot be stopped right now. Try stopping the device again later."
A. This means that the driver is being used by a program. First close all the programs that use the EV2300 and try again. If you still get the same error then open task manager(Press Ctrl-Alt-Del simultaneously and select "Task Manager") and kill any programs that use the EV2300. Check the "Processes" tab also and right click to choose "End process" to kill the program that uses the EV2300 and refuses to quit.
