Ok, I've been through linuxdoc.org, looked at the doco's there. Did a google search on it too.

So far I've got acm in /dev/usb/ and /dev/modem linked to /dev/usb/acm/0

That's all I could find, though, and no power is getting through to the modem.

It's a netcomm roadster II USB, AM5050R3

Any help on getting the modem operational (do I need drivers? Does the kernel need any 3rd party helper app?) would be much appreciated.


EDIT: Read the How To Ask Questions doco and fixed up the post a little.

Never mind guys, I got it working in the end


Now to configure iptables *groan* ;P

Any tips, share the knowledge and tell us all how?

I just brought the exact same modem and I should recieve it today.

Well, I've had to reinstall slackware now as there was a pppd respawn script that went haywire on the system and I couldn't for the life of me remember where I put it...

So anyway, to get power to your modem (this is under slackware, not sure about other distros) issue these commands:

/sbin/modprobe acm
/sbin/modprobe usbcore
/sbin/modprobe usb-uhci

after you modprobe usb-uhci you should get power to the USB device.

I've done all that again, and I've put this line in /fstab

none /proc/bus/usb usbdevfs defaults 0 0

however THIS time around the acm subdir isn't showing up in /dev/usb/ no matter what I do *groan* and for the life of me I can't remember how I got it there in the first instance

Oh well! Back to reading docos incessantly.

well, what do you know. If you put the *CORRECT* search string into google, you'll find the right link. Mess it up by a hair though... and it's like looking for aforementioned hair in a barbershop's sweepings.


These commands will add the device nodes you'll need, which would be the /dev/acm ones I was lacking a few minutes ago

mknod /dev/usb/ttyACM0 c 166 0
mknod /dev/usb/ttyACM1 c 166 1
mknod /dev/usb/ttyACM2 c 166 2
mknod /dev/usb/ttyACM3 c 166 3

Only got one modem? You'll only need the first line.

Thanks for that I will try it out in the next few days and see how I go.
Cheers,
Steve

For anyone interested, it works in RH 8.0 with minimal effort.
It gets detected ok at boot.
Configure which port to use, speed, vol etc and all is well.
Set up ppp and away U go!
Not working atm but thats prob my install as it did not complete 100%
