The plusb driver should detect it as a network interface. It's faster than a 100Mb/s ethernet adapter and slower than a gigabit ethernet adapter. Plug it in to both sides and pick an IP range. Let's call it: A: 192.168.42.1/24 B: 192.168.42.2/24 So to find your adapter name, you say: ip link show and eliminate the ones you know about - lo, eth0, wlan0, whatever - and find the one that's new. Let's pretend it's called usbnet0. Assign it an address: ip address add 192.168.42.1/24 usbnet0 (and on B, use ...42.2 ) You should get a route on each side: ip 4 .... 192.168.42.1/24 dev usbnet0 proto kernel scope link src 192.168.42.2 ... and now you can access the other side via ssh and scp and whatever. -dsr-
