Hello,

What function when running the nrf_drv_usbd_errata_104 function?

The nrf_drv_usbd_errata_104 function is an inline function used to check whether the chip you are working with requires the errata 104. The errata 104 is only present on the Engineering A version of the nRF52840, which you should not use for product development. If you are using a nRF52840 Engineering A version SoC please upgrade to a non-engineering version SoC. 

Do I have run it?  Can I remove this funcction?

It is a convenience function to check whether the chip you are working with requires the errata 104 or not. You do not have to run this, but your question makes me wonder; are you experiencing any issues with this function? Or in general, what is the reason for your encounter and questions with this function?

I am not sure that I have understood your question correctly. In the case that I have misunderstood what you are asking about, please elaborate.

Best regards,
Karl
