How to install the c2000 usb driver for windows on win7 32bit?

Hi Lam,

The device drivers should be included with the code composer studio installation. If you mean you would like to use drivers without CCS then you need to set up and use the FTDI drivers, I'll see if I can remember how I did this for the F28027 Piccolo ControlSTICK and detail it below, but you may need to play around with it a bit to get it to work exactly. I worked this out by using the FTDI driver and documentation from the FTDI website.


Guide to converting FTDI driver for use with TI TMDS28027USB ControlSTICK
=========================================================================

To create a driver that works with the device, first obtain a copy of the FTDI
D2XX driver files.

As the FTDI application note, AN_119 notes in chapter 5, § 5.1, the default
driver files will not work with the device without adjustment as the device
EEPROM has been set by TI to use a non-default PID value, currently **A6D0**
(Hex).

This may be confirmed by connecting the device and using the FTDI utility
USBView (available from www.ftdichip.com/.../Utilities.htm) to view
the PID the device uses.

New .inf files need to be created with the adjusted PID value. This can be
achieved using the FTDI utility FT_INF (also available from
www.ftdichip.com/.../Utilities.htm) to create new ftdibus.inf and
ftdiport.inf files. These files should then replace the default versions.

Once the PID value is updated chapter 3 of the same application note can be
followed to manually install the driver for a connected device.

Creating the Release driver package
===================================

The driver package should include the FDTI D2XX driver files that have been
modified according to the instructions above. Unfortunately this change breaks
the Windows Hardware Qualification so it is wise to rename the driver directory
to remove mention of this (i.e. delete "WHQL" from the directory name).

Installing CDM Device Drivers on Windows OS
===========================================

To install CDM drivers for an FTDI device under Windows 7, follow the
instructions below:

Connect the device to a spare USB port on your PC.

If there is an available Internet connection, Windows will silently connect to
the Windows Update website and install any suitable driver it finds for the
device.

**If the automatic installation takes place there is no need to continue with
the procedure outlined below.**

1. Unzip and save the CDM vx.x.x.zip file to a new directory.

2. If no suitable driver is automatically found then the following procedure
should be followed.

3. Press the Windows start button to bring up the start menu and select
“Control Panel”. From the Control Panel window select Hardware and Sound.

4. At the next screen select Device Manager.

5. In the Device Manager window there will be 2 devices under Other Devices with
a yellow warning symbol to indicate a problem i.e. no driver installed. The text
next to these devices should be "Texas Instruments XDS100+RS232 V1.0".

6. Right click on the one of these devices to bring up a context menu.

7. From the displayed menu select “Update Driver Software…”. This then displays
the option for an automatic search or a manual search.

8. Select the second option to browse manually.

9. In the address box put the exact location where the drivers have been saved
to then select “NEXT” to start the installation.

10. If windows warns that it cannot verify the publisher of the software select
Install this driver software anyway. This warning is due to the change in the
driver to match the processor vendor's change to the USB controller vendor's
device PID.

11. When the installation has finished a completion screen is displayed. Press
Close to close this window and go back to the Device Manager Window.

12. The Device Manager will now show a device under Universal Serial Bus
controllers named USB Serial Converter A. Repeat steps 5 to 11 for the second
Texas Instruments device listed under Other Devices

13. The Device Manager will still show a USB Serial Port device under Other
Devices but in addition to this there is another new entry under Universal
Serial Bus Controllers named USB Serial Converter B. This indicates the bus
layer of the driver is installed. Installing the Virtual Com Port layer of the
driver is almost a repeat of the last few steps.

14. Right click on the device under Other Devices to bring up a context menu.

15. From the displayed menu select “Update Driver Software…”. This then displays
the option for an automatic search or a manual search.

16. Select the second option to browse manually.

17. In the address box put the exact location where the drivers have been saved
to then select “NEXT” to start the installation.

18. When the installation is finished a completion screen is displayed. Note
this screen also displays the COM port assigned to the device. Press Close to
close this window and go back to the Device Manager Window.

19. This time the Device Manager does not have a related entry under Other
Devices but does show entries under Universal Serial Bus Controllers and Ports
(COM & LPT). The device is now ready to use on the assigned COM port.


Uninstalling CDM Device Drivers
===============================

Device drivers can be removed by using the Device Manager by simply
right-clicking on the mouse and selecting "Uninstall". This will delete the
associated registry entries for that device only. Windows 7+ provides an
automatic method to delete driver files via a check box to "Delete the driver
software for this device" on the uninstall dialog box.

This stage is done twice. Once for the device under Ports(COM & LPT) and once
for the devices under Universal Serial Bus Controllers.

Windows 2000, XP and Server 2003 do not have this check box, so driver files
and INF and PNF files must be removed manually or by using a custom application.

Some points to note:

* If the files are deleted while other installed devices still require them
then those devices will not work correctly. This can be fixed by right clicking
the device and selecting "Reinstall Driver" which will replace the missing files.

* If a device to be uninstalled is not connected to the PC, the device can
still be removed by setting the device manager to show phantom devices.


Troubleshooting CDM Device Drivers
==================================

### Devices not shown in Device Manager for uninstalling

Devices that have been installed on a system but are not currently available
are referred to as "phantom devices". These devices are not usually displayed
in the device manager, but can be made to be displayed as though they are
attached. This allows device properties to be changed or devices to be
uninstalled via Device Manger even though the device is not physically
connected to the PC.

To display phantom devices in Device Manager, a new system variable is
required. Open "Control Panel > System" then select the "Advanced" tab and
click "Environment Variables". In the System Variables section
(*NOT THE USER VARIABLES SECTION*), click "New...".

In the Edit System Variable window that is then displayed create a new System
Variable called `DevMgr_Show_NonPresent_Devices` and set the value to `1`, then
click OK.

Open the Device Manager and select "View > Show Hidden Devices". Device Manager
will then show all hidden and phantom devices available on that PC as shaded.


### Windows shows a warning that the driver is not certified

This warning is due to the change in the driver to match the processor vendor's
change to the USB controller vendor's device PID. If you are certain of the
source of the driver the warning can be ignored and you can continue the
installation by selecting "Install this driver software anyway".


### Driver will not install on Windows x64
Windows x64 OS may only allow certified drivers to be installed.
