LaunchPad Temperature GUI in Development Kits Posted April 23, 2011 An update to my last message: On another computer I tried to confirm that WinXP would assign a driver to LPad without CCS4 being installed. It did not. DevMgr shows "MSP430 Application UART" listed under "Other Devices" with no reference to a COM port. Thus, I am not sure how the bad driver was installed. Now, with the TempGUI working properly, the TI driver is C:\Windows\system32\DRIVERS\usbser.sys, driverV126.96.36.199 and fileV5.1.2600.5512. My rather incomplete old notes show that this driver was installed earlier but listed as from MicroSoft rathe than TI. I do not trust my note that sayes this was a MicroSoft driver. I am confident that this earlier driver was not working. Thus, I can now only partially define the cause of the problem Thanks for your assistance!
