USB 4.1.1 USBERR_DEVICE_BUSY

[Mike_d]

Hi,

I often end up with a USBERR_DEVICE_BUSY error from using the USB_Class_CDC_Interface_DIC_Send_Data() function.

How do I recover my interface at this point?

Thanks,

-Mike

Hi Mike,

Thanks for your interest in NXP Semiconductor products and the opportunity to serve you.

I was wondering if you can illustrate the detail procedure to replicate the issue, then it will help me to investigate the issue.
Have a great day,
