USB Host to Host Networking
Given two machines with USB and a host-to-host cable you can network between
these two machines. The executive summary was that after I got USB working, load
the "usbnet" module. Then type the command "ifconfig usb0 192.168.0.10
pointopoint 192.168.0.20" where 192.168.0.10 is your machine and 192.168.0.20
is the other machine. You must do this on both machines for the link to be
established. After that you should be able to talk to each other using TCP/IP.
The only problem that I've noticed is that when another USB device is plugged
in or unplugged, it resets the networking connection so that you have to run
The particular hardware that I'm using is "USB Flash-Link"
by Brinco, model number CUF100. The box didn't have a brand name on it. It
advertised itself as "Networking system for PC to PC sharing files,
directories, and drivers, FDD, HDD, CDROMS and Network I/O devices." I'm
networking between a Charmit Pro (Transmeta Crusoe 800MHz) and a Pentium III 1Ghz.
Both machines are running Linux 2.4.18 and the UHCI JE driver.
