Octopi cannot detect printer after failed firmware update  

Octopi cannot detect printer after failed firmware update

I tried to update my i3MK3 with an ARM windows laptop. It gave a failure message, but the printer still worked from the SD card. But Octopi could no longer find a USB connection. I reverted the firmware using an Intel windows laptop and it completed without error. Still no USB port detected. Flashed again to the latest firmware and still, the RaPi Octopi cannot find the printer. The Octopi does find the USB camera and everything else in octopi works as it always has.

Yes, I checked the RPi Port to ensure it is OFF. I tried ON also but no change. I tried a different RaPi running octopi but no change, still not detected. The Prusa board USB port must be working as I can use it to flash the firmware.

Using SSH to check USB ports in octopi with  dmesg  I find the following:

[4.599229] usb 1-1.2: new high-speed USB device number 4 using dwc_otg

[ 5.510002] lan78xx 1-1.1.1:1.0 (unnamed net_device) (uninitialized): int urb period 64

It seems 1.2 is the camera and 1.1 must be the printer, but it is getting unnamed... errors I think.

I am lost. Does anyone have any ideas here? I am guessing that the failed firmware flash left some flag set wrong that is not reset during a normal successful flashing.

Thank You
