TDC1000-GASEVM: Connection problem with : TDC1000-GASEVM & TDC1000-tdc7200EVM

Part Number: TDC1000-GASEVM

Hello,

My 2 boards TDC1000-GASEVM  & TDC1000-TDC7200EVM can't connect as COM Port.

The boards are seen as USB HID, I readed some post on related problem but none resolve it: 

1°) I can't update the firmware .INF ( because Windows said is up to date), even if uninstall USB Driver, the .INF driver can't install it.

2°) I connect the boards on the USB of Computer (not on the hub) and I tried to flash the boards by use of Debug mode with TDC1000_7200_EVM and MSP430 USB Firmware Upgrade Example,
I obtained the same results:

Failed to read data from RAM BSL
Unsuccessful in starting the BSL. Restarting.

Can you help to resolve the problem ?

Can I flash the boards by other way ?

Thanks,
