Ok, I have a cellphone with a USB cable capable of being used as a regular modem to dialup to the net. It works perfectly fine in windows, and I read a small document that some guy said all cell-phone modems will respond to normal AT commands. Im currently running RedHat 7.3 and there is an internet configuration tool. I tell it that I want to add a modem and it asks me for the /dev location of it - and I dont know it. After some research, I found that it should be something like /dev/usb/TTYACM0 or something like that. So anyways, after some looking I found that I could do a mknod command and create a character device or something in there. I did the command:

mknod /dev/usb/ttyACM0 c 166 0

And it made that entry in /dev/usb, but it didnt seem to work. I also wasnt totally sure what the numbers 166 and 0 represent. Anywho, I basically need some guidance about how to create some working entry in the /dev are that connects w/ that USB cellphone cable.

Thanks guys!

hehe...may I remind you that USB was afterall made for Windows...and perhaps Macintosh....I mean people have enough problems as it is with something way more popular than a cell phone USB...such as USB DSL modems... usb is no good man...
you should get the number of that guy you heard that made it run...heh...and call'im.

well, thats what people told me about my internal software-based 56k modem - but then i got it working =)

oh, I didn't say it was impossible...but however I know not 1 person that uses his usb cell phone connector to access the net using windows...so I think there will be a lot less people using this setup with Linux,

Although I don't have a USB-enabled phone, I have seen my European friends using their cell phones as modems via the IrDA port, so at least it's conceivable that it can work. Instead of usbview, do a
cat /proc/bus/usb/devices
(and post what you get, I'd like to see it). If anything about a "Driver=acm" shows up, you may be in business. I presume that you enabled the ACM drivers in the kernel - just making the device files is not enough.

I could also imagine that the phone presents itself as a serial device. Let's see what that proc entry says.

BTW, I came to like USB devices - Microsoft or not, fact is that USB support has come a long way on Linux. I connect to a camera, a floppy drive, and my Sharp Zaurus through USB, and it works just fine.

I connect to a mouse, Dig Cam/Camcorder, Printer, and memory card reader through USB all on Linux. Works great. In fact, when I first started using some of these, all I had to do was plug them in before boot up, then run Harddrake to configure em. Not too shabby either.

Besides the /proc/bus/usb/devices you may also want to do an lsmod and list the results of that as well.
