Issue with optiboot_atmega1284p on Creality 1.1.4 board #26
Description
I'm not 100% sure this is the right location to file the issue; but I'll start here.
I have a Creality Ender 3 Pro 1.1.4 board; which a few guides refer to as a Sanguino / ATMega1284p.
I followed the guide here https://www.fission3d.com/post/flash-bootloader-and-install-firmware-with-raspberry-pi to use the in circuit serial programmer (ICSP) to flash the Optiboot bootloader as obtained from the Arduino IDE Package manager at C:\Users\USER\AppData\Local\Arduino15\packages\Sanguino\hardware\avr\1.0.3\bootloaders\optiboot with avrdude.
The bootloader seems to have flashed fine, and worked for a period of time (a few weeks( using the klipper installation instructions further on in the guide linked above.
Recently, without explanation, I've been seeing a series of errors in the dmesg log of the Raspberry Pi into which this board is plugged:

If I plug the board into another Pi, or another computer, the board seems to function; so, yes - this may actually be a problem with my raspberry pi's USB ports.
What I can't explain is why other USB devices continue to work on that pi: only this device is failing to negotiate the USB connection.
Are there settings in the optiboot bootloader which define the USB host negotiation?
