USB Ethernet adapter names

Hi,

When adding USB Ethernet adapters to BBB, the adapters receive strange names i.e. rename3, rename5, etc. (instead of eth1, eth2). Is there any way to tell the kernel to configure these devices as ethX?

I'm just guessing, as you didn't specify what image you using.. But it
sorta looks like udev is tripping over my "eth0" by default rule.

So Just remove the line after "# BeagleBone: net device ()"
SUBSYSTEM=xyz line in:

/etc/udev/rules.d/70-persistent-net.rules

This udev rule was put in place to easily swap microSD cards with
different BeagleBone/BeagleBoneBlack boards to always get 'eth0' by
default.

Robert,

I am using your latest published image (with 3.8.13-bone40 kernel). You are correct about the rule. When I removed it, the ethernet adapters are now named properly.

Thanks very much!
