OK, i try to solve one problem after the other. Let's accept that
every new USB-NIC gets a new name for now (using a pool of interface names).

I've tried to create a /etc/network/interfaces which fits my wishes:

------------->snip<----------------
# /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)

# the loopback interface
auto lo
iface lo inet loopback

# interfaces to bring up at boot time
auto eth0

# the onboard NIC
iface eth0 inet dhcp

# interfaces to bring up when hotplugging
allow-hotplug eth1 eth2 eth3 eth4 eth5 eth6 eth7 eth8

# additional USB-NIC's
iface eth1 inet dhcp
iface eth2 inet dhcp
iface eth3 inet dhcp
iface eth4 inet dhcp
iface eth5 inet dhcp
iface eth6 inet dhcp
iface eth7 inet dhcp
iface eth8 inet dhcp
------------->snip<----------------

This works fine when hotplugging, but the USB-NIC is not recognised
when connected while booting up. :(

I tried to change the one line responsible for that to

  auto eth0 eth1 eth2 eth3 eth4 eth5 eth6 eth7 eth8

This works better but leads to dirty errors messages while booting
and shutdown for disconnected interfaces:

boot:
eth1: unknown interface: No such device
eth2: unknown interface: No such device
eth3: unknown interface: No such device
eth4: unknown interface: No such device
eth5: unknown interface: No such device
eth6: unknown interface: No such device
eth7: unknown interface: No such device
eth8: unknown interface: No such device

shutdown:

eth7: unknown interface: No such device
cat: /var/run/udhcpc.eth8.pid: No such file or directory

done.

I'm not really happy with that. :(
