USB example .inf file not working

lucky1408 — Tue, 28 May 2019 05:39:31 GMT

Hello,

I'm trying to use the USB port as a virtual com port. I've found the example from the SDK, but when I try to install the driver which is situated in the "inf" folder I get the following error:

I've downloaded the latest SDK version, but that didn't solve the problem.

Does anybody have any experience with this?

My board is the: IMXRT1050-EVKB

With kind regards,

Luc

Hi Luc Aarts

Could you clarify what SDK example are you using? If possible please try to use another .inf file with the example that you are running. Another option is using another driver for the example.

NXP provides "demo projects" with an INF file using NXP's VID/PID. It is the customer's responsibility to get their own PID/VID and get the INF file certified by Microsoft for the end product.

Have a great day,
TIC

Hello jorge_a_vazquez,

I'm using SDK 2.5.1., but after using a different inf file it worked.

How do I change the VID and PID?

With kind regards,

Luc

Hi Luc Aarts

Please check the following post:

NXP USB VID/PID Program

The VID and PID are specified in the USB descriptor
