I was happy user of MK2.5S until i've tried to upgrade it's firmware.

Before i was printing from SD, from PrusaSlicer (USB) or from octopi - everything was fine.

 

the update didn't worked, it told me right away in the begining

avrdude-slic3r done. Thank you.

but since then i'm not able to print from prusaslicer/octoprint over USB at all 🙁 not from my pc neighter raspberry is connecting 🙁   (however it's still working from SD)

in the system log i can see the printer being connected, but ...

i've restarted both the printer and my computer, tried different usb cable but nothing helped 🙁

in octopi terminal i found this: https://pastebin.com/9dw6GuM8 (i'm unable to paste it here due to some forum security)

i'm more and more confused, it looks as if the usb chip on the RAMBO board is broken, but then he shouldn't be able to identify himself properly - see first message in this thread

I believe I have the same issue. Same Prusa model.
