[SLUG] USB modem in redhat 8.0

[Melinda Taylor]

Hello,

I am trying to get an Acer AMU-AU00 modem to work in linux. It is listed as a modem that will work under linux
so I hope luck is on my side. I am just wondering what is a quick and easy test to find out what
devfs the modem is on ie is it /dev/usb/ttyACM01 or /dev/usb/ttyACM02 etc. Is there some file
which tells you this info?

The modem seems to be working, the hardware browser shows it and the output of lsusb
shows it too (see below for the output related to the modem).

However when I try to make a connection whether using minicom or others
and fiddle around with the device name I can't get it to work or make a sound or for
the lights to flicker.

Can anyone suggest an even more basic test than minicom or a way to find out what
/dev/usb/ACM??? I should be using?

Note that I created the /dev/usb/ttyACM01 using the mknod command as suggested in the USB how-to.

Any suggestion of things to try are appreciated.

Ta :)
