STM32 RNDIS USB device disappear after a while

Hello,

I'm opening a new conversation to address another issue(Issue with VCP and RNDIS ). Previously, I successfully implemented RNDIS on an MCU, and I can see the Remote NDIS based Sharing Interface in the device manager. However, after about 20 seconds, it changes to a "Failed Enumeration Device" state.

Here is my device descriptor:

I also checked USBView details before and after the error, and it happens consistently after every reboot. I want to mention that I haven't implemented any IP stack. Could this be the cause of the issue?

 

"Trwa identyfikowanie..." in Polish means "Identifying..."
