Hi,

My devkit shows up in dmesg;

#  dmesg | grep cdc
[10232.643261] cdc_acm 1-6.1:1.1: ttyACM0: USB ACM device
[10232.647089] usbcore: registered new interface driver cdc_acm
[10232.647095] cdc_acm: USB Abstract Control Model driver for USB
modems and ISDN adapters
[10245.873686] cdc_acm 1-6.1:1.1: failed to set dtr/rts

But it disappears at some point because I cannot find it in /dev/ nor
connect using picocom. 

When I reboot the device into another mode than emmc, it shows up as a
USB HID which I imagine is the expected behavior. I'm working from
here: 
https://developer.puri.sm/Librem5/Development_Environment/Boards/imx8.html#dev-board-figure

I wonder if anyone else has seen this behavior?

Cheers,

Jeremiah
