I'am working on USB on the MIMXRT1176 and i have some questions:
1- I tested CDC class VCOM, but the speed seems to be slow for my usage (~300 KB/s), am i looping something to speed up the transfer? I tested the MSC class and the transfer speed reached about 5MB/s, i don't understand why i can't reach such speed on CDC class.
2- For the CDC VNIC SDK example project, there's no lwip stack, how can i test transfer (file or data) with this example for the RNDIS class ?
3- Is there a specific recommended class to reach high speed transfer on USB ?
