TUSB Driver Issue - Multiple FET tools plugged into computer...

Hello everyone,

 

The MSP-FET430UIF tool may have some issues when multiple instances are plugged into the same computer. Below is a description of this issue, as well as a work around to get you up and running.

 

  • Description of the issue:
    • After connecting (enumerating) a new USB device while working with the MSP-FET430UIF, IAR or CCS reports an error, and it is not possible to connect to the UIF. Your IDE will report a malfunction, and an error popup window will show.
  • How can I detect this issue:
    • There is no easy way to find the issue without special software (e.g. USB Viewer). The issue is encountered if two MSP-FET430UIF tools are connected to USB ports of the same root hub. A typical PC has several few hubs, with each hub having a few USB ports. In many cases, USB ports of one root hub are normally located on one side of a notebook laptop. USB ports on the opposite side are connected to another root hub.
  • How can I work around this issue?
    • Try to separate the two MSP-FET430UIF tools into separate USB root hubs (opposite sides of your laptop or desktop).
    • Replug one MSP-FET430UIF tool on one side, then plug the second tool on the opposite side.
    • At this point, each IDE should recognize the separate MSP-FET430UIF tools. A restart of your IDE maybe required.
  • Possible root cause of this issue?
    • Bug in the driver of the TUSB3410. This has been reported to the TUSB3410 team, and an updated driver is in the works.

 

Thanks, and look forward to a solution in the future.

    Hello Adrian,

    Has the bug been resolved in the TUSB3410 driver yet?

    Thanks,

    Hi John,

    considering this is quite a very old thread, i would assume this bug should have been fixed in the meantime. I remembered i had no problem using two USB FET on my laptop. If you have a problem with it, i would suggest you to start a new thread describing the problem in detail. If it is a serious one, i would try to contact the tools team to look at the problem.

    Thanks.

    I have no problems running a FET-UIF and a LaunchPad at the same time (of course I have to select the right one in the programming software).

    But it might be that there are problems if two identical devices (two FET_UIFs) on the same root hub. Pluggng one to the front USB conenctor and the other one to one on the backside (maybe with an USB extension cable) might solve the problem then.

    Jens-Michael,

    I am working with a colleague and we have both had the same issue with running multiple FET's.  He is using CCS most of the time and I am using IAR.

    We have picked up 4 of Gregory's Elprotronic FPA's in the last couple of weeks - and that has solved the issue.  There is still a DLL that needs to be brought current with IAR 5.50.2 but the issue with that is minor as compared to having things not work.

    So, until I hear otherwise or have some hard evidence that the TUSB3410 bug has been resolved/solved/fixed/whatever - this bug is still very real on the projects I am currently involved with.

    Best Regards,
    John W.

    Folks,

    Just got an update on the situation from our developers:

    The TUSB3410 bug was solved with updating the FW for the TUSB. It happened with switching to MSP430.DLLv3 last year.
    I don’t see any problem to use multiple UIFs on one PC. The IDE team uses two UIFs on one PC in regression tests.

    Regards, Dietmar
