Need help! Can't get device mode to work.

@scanboy , were you able to get the device to enumerate?

I am running a Debian 5.15 kernel that does not have USB_OTG or device-tree OVERLAY enabled.  The original device-tree has dr_mode="host", so:

• on the  running system I edited and replaced the dtb so that dr_mode="peripheral"
  
• I can set up the configfs  /sys/kernel/config/usb_gadget/g1/ with files according to recipes for enabling RNDIS
  
• /sys/class/udc has content, so I no longer get the "could not find an available udc" complaint
  
• modprobe what look like the right drivers, and I see the kernel message g_ether gadget: g_ether ready
  
• ip address shows usb0
  

I am trying to connect to a Windows 10 PC, and I get USB device not recognized when I plug in the cable, and running usbview.exe I see the real problem is FailedEnumeration.

So I think we are at the same point: the rockpro64 gadget is not responding to enumeration requests.
