Part Number: DS90UB947-Q1
Other Parts Discussed in Thread: ALP, USB2ANY

Hi Team,

Could you let me know why my laptop couldn't find the undefined ALP device(USN2ANY)? 

I use the another laptop,same USB2ANY and same system board(947), the ALP could work. I have re-install the ALP and ALP_update, but there is same issue. Could you let me know the solution?

ps. Another laptop is using same installation step.

Regards,

Roy

    Roy,

    Please check this post

    e2e.ti.com/.../3055424

    If user mistakenly removes USB2ANY itself instead then the issue you are facing happens. After this, ALP cannot find USB2ANY because the USB2ANY driver associated to the device is removed and in default enumeration USB2ANY doesn't come up. USB2ANY works as a HID device and when this association is removed a standard microsoft driver gets associated. I tried different things by finally the steps that helped to get ALP to work on my windows 10 computer are the following

    a) Make sure your board is updated to firmware version 2.7. I found DLL version 2.6.and above automatically support firmware version detection/update so update to version 2.7

    b) Quit ALP, remove usb cable connected to PC

    c) Uninstall in Programs and Features both Analog LaunchPAD frame work and ALP Profile Update. As there is some dependency between the two, it takes a few tries to fully uninstall them. 

    d) Also, you have to manually go the following install folder

    C:\Program Files (x86)\Texas Instruments

    and remove completely Analog LaunchPAD v1.57.0010 folder

    e) Reboot your computer

    f) Reinstall ALP framework and latest ALP Profile Update

    g) connect 947EVM board again 

    h) Right click and Restart ALP in admin mode

    Please try and hopefully it works for you again.

    Thanks,

    Vishy

    Roy,

    In the same e2e thread

    e2e.ti.com/.../3035945

    Further down I have suggested using a tool usbdeview and find all USB2ANY device (VID = 2047, PID = 0301) and right click to uninstall them and then reconnect. Please take a look at that suggestion and try it. This worked in a 2nd PC with this problem. 

    There's also another customer who got into this issue and fixed it in the above way. If I find that e2e link, I will share that.

    Thanks,

    Vishy
