Why would you need a USB 3 port ? Doesn't a USB 2 port provide enough
throughput ?

These are serial ports, not network interfaces. With the proper driver,
an ethernet over USB device will appear as a regular network interface
in ifconfig. Well, the interface name may be different from the usual
ethX, such as usbX.

I do not know.  If USB2 provides reasonable performance, then I am satisfied.

Such as the Apple usb-to-ethernet adapter?

But does IPCop recognize such a device when it is plugged into an RJ45
ethernet port?

If I go out today and purchase an usb-to-ethernet adapter, is it likely to
work?

Maybe, if the chip inside is supported. But why does it matter ?

Err, no. You must plug it into a USB port.

No. You don't need that. The USB device I'm talking about is the Netgear
AirCard 791L hotspot in "tethered" mode. So all you may need to buy is a
USB cable with the proper connectors at each end if you don't already
have one, to connect the USB port on the hotspot to the USB port on the PC.

I have on my desk a 791L with the USB cable.  And I have a spare
desktop machine here -- in good running order -- with which to
experiment.  Finally, I have an IPCop 2.1.8 installation CD.

So I start by:

(1) installing IPCop

(2) turn on the VerizonWireless AirCard 791L

(3) plug the USB cable into one of the USB ports of the new IPCop machine

Installation is successful.  Next, I:

(4) remove the installation CD

(5) continue the installation by naming the machine

and then I stall, at the dialog asking configuration type for RED
interface.  The options are:

   - analog modem
   - GSM/3G modem
   - ISDN
   - PPPoE
   - PPTP
   - static
   - DHCP

What now?

DHCP, I guess.

That does not appear to work.  I have tried every item on the list, but
keep getting the message:

"No RED interface assigned.  Do you want to change RED type to Analogue
Modem?"

But is the Verizon-Netgear AirCard 791L a "GSM/3G modem"?

IIUC, according to the user guide it should be seen as a network
interface. Can you identify the device with lsusb ?

Something else:  the AirCard CONNECTED DEVICES screen shows one USB
tethered, with the IP address 192.168.1.4 and the MAC address
08:BD:43:34:15:9A.

I have been poking around, but I have not yet discovered the device which
corresponds to that MAC address.

What does "ifconfig -a" display ?
What are the new messages in the kernel log after plugging the device ?

According to <http://forums.whirlpool.net.au/archive/2176502>, the
device should work with the "rndis_host" kernel module.

You can print the module alias of the device with :

find /sys -name "modalias" -execdir grep -i "v0846p68e1" '{}' \;

and check which module supports it with :

modprobe -R <alias>

On the whirlpool web page I found a link to a Netgear web page

http://www.netgear.com/home/products/mobile-broadband/hotspots/AC791L.aspx#tab-accessories

which shows the "AirCard 4G LTE Signal Boosting Cradle with Ethernet
(DC113A)".

That looks like your hotspot device right there.  You can't assign eth0
to be your "RED" interface?

I do not know how; the dialog asking configuration type for RED
interface has only the following options:

   - analog modem
   - GSM/3G modem
   - ISDN
   - PPPoE
   - PPTP
   - static
   - DHCP

You might have more luck on the IPCop list  ipcop-user@lists.sourceforge.net

Thanks.  I have posted there (but not a cross-post) as well as on the
Netgear list.

And perhaps I can find a Netgear DC113A.

Looks like the interface we're looking for, although the MAC address is
different from what you read on the device screen (08:BD:43:34:15:9A).

Now you can try to set the interface up, run a DHCP client on it
(dhclient, pump, dhcpcd, udhcpc...) and check what happens.

Note : according to what you read on the device screen, it uses an IP
address in the same range so you may need to set a different subnet on
the LAN interface.

Confirmed by the kernel log.

Really ? Even though the rndis_host module was automatically loaded ?
On my box it returns "rndis_host" for the first alias returned by the
previous command :

modprobe -R usb:v0846p68E1dFFFFdc02dsc00dp00icE0isc01ip03
rndis_host

IPCop responds only to dhcpcd; but I do not know what to specify, and to
get the man page I need to stop and install dhcpcd5 on my desktop.

How about 192.168.3.1 ?

Forgive me; obviously I did something wrong; perhaps I forgot the "usb:". 
Anyway, I tried again, and this time output was returned:

For usb:v0846p68E1dFFFFdc02dsc00dp00icE0isc01ip03
the result is             2dsc00dp00icE0isc01ip03

For usb:v0846p68E1dFFFFdc02dsc00dp00ic0Aisc00ip00
the result is             2dsc00dp00ic0Aisc00ip00

You can read most man pages online at manpages.debian.org and other
websites.
