Answer 1

If your Linux is configured to support SocketCAN, the USB2CAN device should be supported.

Mainline Linux has supported this interface since kernel version 3.9, via the usb_8dev driver.

I am using both the rev.1 and rev.2 USB2CAN adapters with out of the box Ubuntu 18.04 and 20.04 distributions.

$ lsmod | egrep 'can|8dev'
can_raw                20480  0
can                    24576  1 can_raw
usb_8dev               20480  0
can_dev                28672  1 usb_8dev
