I made a minipcie board with HL8548 , I tied the USBVCC to VBAT according the specific ,the linux sytem can detect the 8548 ,and also create 5 :slight_smile: usb ports ,from acm0–acm4 ,but can’t creat the eth1 port. you can see the below information

Hi,

Bit late to respond but anyway you probably need to change the USB configuration of the unit with the at!kusbcomp command, the default will create all of the /dev/ttyACM ports and no ethernet interfaces, if you send at!kusbcomp=1 then reset it you should see some interfaces appear.

Regards
