@voedipus Thank you for the PR! Does the RNDIS configuration work with your device?

we did not test RNDIS, only NCM. That is why why enabled NCM only

@tore-espressif Actually, it is not working with this MR, but I was able to get RNDIS working with couple of other fixes. I will add changes soon

@tore-espressif It works now, checked on Linux with esp idf 5.1.3 and Windows 10 (RNDIS)
