USB network adapter insertion/removal creates multiple entries in 70-persistent-net.rules

[slashtom]

Binary package hint: udev

Udev version: 147~-6.1
Ubuntu: 9.10
USB Network Adapter (SMC Networks): ADMtek, Inc. AN8513 Ethernet

When the USB Network Adapter is first inserted it creates an entry in
/etc/udev/rules.d/70-persistent-net.rules, as expected:
-------------------------------------------------------------------------------------
# USB device 0x07a6:0x8513 (usb)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:10:60:3b:b6:7
a", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"
-------------------------------------------------------------------------------------

If the computer is now rebooted everything works fine and continues to work fine, but if the USB Network Adapter is unplugged and reinserted before rebooting /etc/udev/rules.d/70-persistent-net.rules now contains:
-------------------------------------------------------------------------------------
# USB device 0x07a6:0x8513 (usb)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:10:60:3b:b6:7
a", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"

# USB device 0x07a6:0x8513 (usb)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:10:60:3b:b6:7
a", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth2"
-------------------------------------------------------------------------------------

And from now on, every time the USB Network adapter is reinserted a new entry in /etc/udev/rules.d/70-persistent-net.rules is created with an incremented interface name.

Echo this. At one point I ended up with eth1 through eth12 on my machine, which were all identical devices. Network manager in turn added a new device for each, which was a right pain as I kept having to reconfigure my static IP. It only stopped adding new devices when I rebooted with the USB Ethernet driver attached.

Having to reboot after adding a piece of USB hardware is the kind of thing you'd expect from windows.

I'm also effected by this bug, with the built (PCI) 3-port NIC on my computer (lucid server). After every hard poweroff, my network entries keep increasing. This makes the computer completely unusable for me.

The only thing really out of the ordinary on the box is that I disabled ACPI (the system wouldn't boot otherwise) in the BIOS -- not sure if this is related.
