Re: [Gumstix-users] Changed SMSC chip?

[Gavin S. <gav...@gm...>]

I found an article that mentioned creating an empty generator rule in
/etc/udev/rules.d. That will prevent the one in /lib from running.
This leaves me with the preferred outcome of the only eth device
becoming eth0.

I have added a touch command to my udev recipe. Hopefully this will
fix the problem. I'm wondering if this is something that should not be
the default for the gumstix platform? Having your devices move from
board to board with the same SD card does not seem like the behavior
anyone would want.
