MSP430FR6043: HID Bridge won't communicate?

Part Number: MSP430FR6043

Hello everyone.

I am working with a MSP430FR6043, trying to port over some custom code for testing, as well as trying to connect to the USS GUI Tool. I am experiencing a problem with the HID Bridge based on my research, but none of the solutions I have found have worked.

I have connected to and successfully used the USS GUI tool before, however today when starting it up, I get the error "More that one HID device with the same VID/PID detected. Only one device may be connected."

When starting the MCU (with the "default config" for jumpers), LED201 lights up steady. LED202 blinks for a few seconds, then stops blinking. LED102 lights up steady.

Things I have tried,

Reflashing HID Bridge with MSPWare Python Tool (didn't work, can't get the HID bridge into BSL mode) via 

Reflashing the USS GUI App Code with both IAR and with MSPFlasher (no change)

Reflashing HID Bridge with MSPFlasher Tool (no change)

I can't seem to figure out exactly what LED202 flashing 2.5 times on startup actually means. (By 2.5 I mean 2 normal length flashes and then half of a flash)

Any advice is greatly appreciated, thankyou.

    Hi,

    It seems this issue is related to the PC. Have you tried to restart you PC or tried on another PC?

    You lights are correct.

    Yes, The LED202 flash 2.5 times means the HID interface has connected successful. And it is 2 normal length flashes and then a half length flash.

    Hmm, I have a second board which works completely normally with no problem connecting to this PC. I've restarted a number of times just throughout my normal use with no change. Is there an area of the PC I should look into to try and resolve this you think?

    Thanks.

    Hi,

    Well, you may check if there is another device using the same VID/PID as this EVM board in the Device Manager.

    Best regards,
