Hi,

I am testing the USB_dev_cserial example on TM4C1294XL LauchPad board with my laptop which is Win10 with USB3 ports. 

I got an issue that the USB Composite Device doesn't appear on Device Manager. I tried to update driver with the Windows package come with TivaWare C Series 2.1.3.156. but no luck. my laptop run Win10 and it only has USB3 ports. I tried same example code on Win7, which works.

Can anyone help on this? 

here is the screen shoot of the Device Manager:

Thanks,

Jeff

    Hello Jeff,

    The TivaWare USB Composite example is not currently functional with Windows 10 due to a change in how Windows 10 enumerates USB Composite devices. Resolving this issue is on our to-do list, but as of right now it is still an open issue.

    From the research I've done, I suspect the root cause lays with the descriptors sent to Windows 10 specifically for the USB Composite example.

    There was one customer who was able to have success with a workaround, but that hasn't proven reliable for all users. You might want to try it just in case though. The post that describes the workaround is: e2e.ti.com/.../2268171

    Hi Ralph,

    I have tried the solution you posted in the link, but no luck.
    I updated windows driver with the patch and replaced c file you suggested. The USB Composite Device still has the warning.
    I am a hardware guy. It is a little hard for me to dig into the Windows USB driver. So I will wait for TI to have a completed solution. It is a little bit wield that the Stellaris virtual serial port shows up without any problem.
