I tested to access the console via usbacm and it worked on my imx28evk:

--- a/configs/mx28evk_defconfig
+++ b/configs/mx28evk_defconfig
@@ -70,3 +70,5 @@ CONFIG_USB_GADGET_VENDOR_NUM=0x0525
 CONFIG_USB_GADGET_PRODUCT_NUM=0xa4a5

 CONFIG_USB_GADGET_DOWNLOAD=y
+CONFIG_USB_FUNCTION_ACM=y
+CONFIG_BOOTDELAY=100

First, I booted via normal serial console and run:

=> setenv stderr usbacm && setenv stdout usbacm && setenv stdin usbacm
&& saveenv

Then booted again, and I saw on the console:

U-Boot 2025.01-dirty (Jan 07 2025 - 16:10:42 -0300)

Then, on another PC window:

sudo picocom -b 115200 /dev/ttyACM0

And the console can be seen there.
