Personal experience: I run an IPCop box as a firewall for my LAN, using three USBtoRJ45 interfaces in an attempt to reduce the motherboard damage from thunderstorms (I live in Darkest Paraguay).

The local electricity system is not all that reliable, and even with a UPS the box gets rebooted several times a week.

In around ten years of use I have never had the problem of USB/NIC assignment changing at reboot, except when I had to replace a burnt-out USBtoRJ45 ;-3(

Cheers,

Ron.
