RISC-V: couldn'n recognize M0sense board

I'm connecting Sipped M0sense board to an amd64 Gentoo machine from a USB 2.0 port, it consumes 0.5 A and therefore this USB port must supply barely enough power, the board turned on and LCD screen light up but /dev/ folder doesn't show new connected devices, it isn't recognized. I've followed the guide and connected boot and 3.3V pins, tested it on windows but it isn't recognized, some users managed to recognize it as /dev/ttyACM0 device, consequently I enabled CONFIG_USB_ACM=m on linux kernel, the only output when I connect is:

Code: Select all

The first result I see when I search for the error is that USB is protecting against too much current draw on the port. Try an external power supply.
