Hi,

I have a Netgear DM602 Ethernet/USB modem/router.  I can use it with my
ethernet card as a router or with USB as a modem, in which case my ISP
asks that it must run in "bridged" mode, which I understand to be modem
mode, not router mode.  This is apparently where the modem simply passes
on whatever it gets, either way, without interfering.  Not sure really.

The ACM driver on kernel 2.4.22 doesn't register itself with this
device, even though lsusb reveals two USB devices or whatevers, with
type 'comm.' and type 'data' leading me to believe it could work with
that driver.  Apparently if it had a proprietary interface it would show
up as type=ff(vend.).

If bridged mode is what I think it is, then I should be able to write a
simple USB driver that is like a pass-thru device, not doing anything
other than making the data transfer happen between pppoe/whatever and
the device via the USB stack.  I am sure I can manage that much.

The driver that claims this device on kernel 2.4.22 is hub.  Is this
wrong?  Can I simply issue the command as given in the USB guide:

mknod /dev/usb/ttyACM0 c 166 0

My DM602 is showing up on /proc/bus/usb/01/02.  I have no idea what this
means.  I think it means that it's on the first USB port.  Not sure what
the '02' is for.  There is only one USB port and one device that
attaches to it.  (I wonder what the comm. and data devices are?  Are
they separate chips inside the DM602?)

Actually, I am using Slackware 9.1 on the IBM Thinkpad iSeries laptop,
and I'd like to get rid of the 2.4.22 kernel and compile and use a 2.6.6
kernel instead.  But the last time I tried to do it with kernel 2.6.0
the system was thoroughly FUBAR. :-/  Not sure if I am supposed to
compile and install a 2.6.x kernel on a system which uses a 2.4.x
kernel.

Thanks!
James
