Hi Lisa,
I tried to use the software from "www.elprotronic.com" and upgrade, downgrade. But the state continue the same. In one moment after the downgrade the FET was recognized with the name "TUSB..." in the device manager, but after the upgrade return to the normal name "MSP-430FETUIF-CDC...".
When I tried to use the "MSP430Flasher_1.3.1", after insert the partnumber "msp430g2955" the software recognize the FET int the COM3, but after the software stopped and exited of the application.
Tomorrow I will try to realize the same process in another computer.
