Is there an error report for USB packet retransmits

Postby sabdulqadir » Tue Jun 30, 2020 4:36 am

Hi,
I am using stm32f723 and as a usb cdc device. I was trying to see if there is any api available which gives me health status of my usb link. How many packets got dropped or retransmitted etc. Would you guys know of any such stats available?

Thanks,
AQ

Hi,

There is no such API, not all USB peripherals support that kind of statistics.
