does this look right?

root@luckfox:/etc/profile.d# cat /var/log/usbdevice.log
[1970-01-01 00:00:12] usbdevice: Handling start request
[1970-01-01 00:00:12] usbdevice: Run stage: usb_prepare

So, has to be in kernel, cannot be a module. will try that.

Greetings,

I need serial communication over USB but i cant get ACM working? i tried to follow the instructions for pico viewtopic.php?t=1157 but i'm not having any luck? Ethernet and ADB work, but just not serial, no tty. Im just using the SDK.

Thanks for your time
