USB serial not working #15

Open T00ManySecrets opened 2 years ago

T00ManySecrets commented 2 years ago

Description

No way I can get the USB serial port to work.

Steps to Reproduce

Malyan V2 board with stm32f070cb Compile M200Fixes2 in Arduino ide

Expected behavior: [What you expect to happen] Working board with working USB Actual behavior: [What actually happens] Board works and the LCD works, windows has problems with the USB driver, and even if it installs a driver that starts it won't open on any serial port monitor.

Additional Information

This is not the only firmware version i tried. I tried up to Marlin 2.0.6.1 and all compile with the STM core 1.7 for Arduino ide but none of them have the working usb. I can confirm its not a cable or USB connector problem as on the original MPSM firmware the USB works normally.
