[BUG] MKS Robin nano v3.1 USB disk not working in color_ui

[hwystitch]

Did you test the latest bugfix-2.0.x code?

Yes, and the problem still exists.

Bug Description

USB disk works on the tft_lvgl but doesnt work when using the color_ui. Is there a setting that needs to be changed to get the USB disk working with color_ui? I like the color_ui interface better than the tft_lvg since I have a dual parts fan setup and the tft_lvgl only has one control for the part fans along with many more settings to tune the printer on color_ui. thanks for any help.

I tried changing the serial_port to 3 also -1 and tried to add a second but nothing works. I do have the USB flash drive support enabled in the advance config.
