Configured RUMBA32 board +Marlin 2.0.7.2 can't be used with USB host.

[PaXLiCh]

Successfully flashed marlin with platformio. My configuration work with fullgraphics lcd. TFT70 also works with this board. But I cannot connected to board with USB. Pronterface and cura can't find my printer. If I press "Connect" in pronterface, I can get only infinite "Connecting...". Cura with MKS WIFI plugin can't see the printer by specified IP. Tested on various machines and systems (win 7 10, linux x86, macos x). Seems to me, board cant send data to host. I disconnect TFT70 (which uses USART), but no luck. My config files Any ideas?

Hallo,

ich hatte da gleiche Problem, jedoch mit folgender Konfiguration hat es dann funktioniert:

1. COM-Anschluss konfigurieren: BAUDRATE auf 115200 setzen.

2. Configuration.h anpassen: BAUDRATE auf 115200 ändern. SERIAL PORT 2 aktivieren.

3. Repetier Host anpassen:

Es funktioniert mit Pronterface und Repetier Host.
