MSP-EXP430G2: Cannot get USB to work

Part Number: MSP-EXP430G2

After puzzling over this off and on for the last couple of weeks, reading tens of E2E threads I can't seem to find a solution.  I suspect that because I first used CCS with the MSP430 USB Debug Interface (MSP-FET 430UIF) that Windows (11 Home 64 bit) has determined that's the correct driver.  When I look at Project>Properties and select "identify I get Error initializing emulator:
Could not find MSP-FET430UIF on specified COM port.

I tried also installing an old rev of CCS (v9) because one thread had a comment that indicated EXP430G2 was no longer supported and that you need G2ET now, but other info suggests that current CCS supports all older hardware.  I tried finding the correct driver, downloaded ti_msp430driver_setup_1.0.1.1  but could not find one that looked appropriate for the G2.

Can you tell if I've correctly identified the problem and point me to the correct driver?  I think I can figure out how to manually install after uninstalling or disabling the existing one but directions to do that wouldn't hurt.

If not, what else can I do or can you point me to a thread I've missed.  There are a ton of threads with similar problems, "already in use" ... problems with UART flash, etc. but none that I could find for this particular problem.

Thanks,
Jim

    Status update.  I dug out an old laptop, installed CCSv9 on it and that works.  Looking at that it seems I have to set the project settings to UART rather than USB.  I did that, got the "can't find COM65" error which is apparently pretty typical.  Went into the ccmxl file and there's no option to delete the alternate, so I changed it to COM5 which is what the USB port enumerates to.  Now it no longer produces an error, however it also hangs at the beginning of loading - 0 bytes transferred.   Port is set to 9600,8,1.  Any ideas?

    As you can see the production page of MSP-FETUIF, it is not recommended to used for new design. We recommend to use MSP-FET.

    https://www.ti.com/tool/MSP-FET430UIF#description

    Due to there is no maintain of the drivers for MSP-FETUIF that means it may not compatible with the latest windows 11. Recommend to buy a new MSP-FET to do the debug.

    I guess I didn't clearly explain my issue as you seem to have misunderstood.  I started out using the MSP-FETUIF  with a MSP-TSA430PW28A target board to program a MSP430G2452 and it works just fine on my Windows 11 home laptop.  Full disclosure, I'm a hobbyist, not a professional looking to develop things to support the use of lithium batteries on boats and it seems MSP430 is a better fit than Arduino's and Raspberry Pi's I had been playing around with.

    I will ultimately want to be using DIP packages so I found on Ebay a(n?) MSP-EXP430G2 with the same processor in a DIP package along with a couple of other MCUs.  However when I tried to use it instead of the MSP-FETUIF CCS apparently used the driver that was already installed.  So I dug out an old computer, put CCS on it and it works with the MSP-EXP430G2.

    To reiterate - my problem is that CCS will not connect to the MSP-EXP430G2 on my current laptop, however it does on my old one.  According to the CCS manual
    "This manual applies to the use of CCS with the TI MSP-FET, MSP-FET430UIF, eZ-FET, and eZ430 development
    tools series."

    Thanks,
    Jim

    The original device in the MSP-EXP430G2 should be MSP430G2553, what you found the device is MSP430G2452 in the DIP package, correct?

    Ok, sorry for the misunderstand about that. As you have mentioned MSP-FETUIF should works fine with your laptop. Now my question is how do you connect the MSP-FETUIF with the MSP-EXP430G2?

    For MSP-EXP430G2 it also have a debugger eZ430 on it as below, have you try that instead of MSP-FETUI?

    The answer to your first question is I don't - that wouldn't make sense.  Both devices connect to the PC with USB.  In the case of the MSP-FETUIF  it connects to the "target board" with the JTAG connector (18 pin I think).  In my case that target is the MSP-TSA430PW28A .  And this works fine with CCS v12.

    The answer to question 2 is yes,  That is the whole reason I started this thread in the first place - I did and it doesn't work on my primary PC that was first used with the MSP-FETUIF.  It appears to me that either CCS or Windows locked in the driver for the MSP-FETUIF  and that a different driver is required for the MSP-EXP430G2.

    I recently purchased a MSP-EXP430G2ET, so I now have 4 different boards that in theory should all work with CCS.

    1. MSP-TSA430PW28A   the first one I bought and what CCS seems to have captured the COM port driver on my newer laptop

    2.  MSP-EXP430G2 v1.4  Does not work on newer laptop with either CCS v12 or v9

    3. MSP-EXP430G2 v1.5  Does not work on newer laptop with either CCS v12 or v9

    4. MSP-EXP430G2ET  I just received this last night and have not tried it yet.

    Can you just provide me names and links to the proper drivers for each of the last three boards on this list.  Thanks,

    Jim
