MSP-EXP430G2: Launchpad not working anymore

Part Number: MSP-EXP430G2

Hello!

I have a MSP-EXP430G2 Launchpad board (eZ430) and it stopped working.

It was without use during about 1 year and when I tried to use now and connected the cable in PC, the board was not recognized and is not enumerated as USB device.

I was looking in the forum for similar issues and didn't find a solution.

I inspect the board and stated that the 12MHz clock is working from MSP430F1612 to TUSB3410 and the voltage in pin 9 (RESET) of TUSB3410 is about 3.4V.

I did another test: I connected VCC to the pin 5 (PUR) of TUSB3410 and then the board was recognized as USB Device (TUSB3410 Boot Device) as shown bellow. But when I disconnect VCC from pin 5 the USB disconnect.

I think it can be caused by corrupted firmware in the EEPROM or in the MSP430F1612.

Someone had the same issue? There is a way to fix it?
