Hi
All,
It just felt like
time to try living dangerously. So I plugged my Zoom 2985L USB, hard modem
into my linux computer. I hoped it would be detected automatically and I
could just use it as /dev/modem. According to the boot-time
messages, the ACM driver appears to have found it as ttyACM0, as I
would have expected. But, there is no indication of the existence of a
/dev/ttyACM0 or anything similar. A cat /proc/bus/usb/devices does not
show a tty device. A cat /proc/bus/usb/ttyACM0 (as I recall), and similar,
gave me no device found errors.
Has someone had
experience with usb modems on 7.2 before? Is there something else I need
to do, like a mknod command to set up the device? I'm sure I've seen
somewhere before that the Zoom 2985L is supported by the ACM driver. It
has an internal controller (it's not a soft modem). I know the modem works
since it's used on my Win computer daily. kernel version is
2.4.7-10.
The boot-time
messages did not exactly match the example in the kernel
usb/acm documentation, so I've copied the log messages relating to usb is
as follows:
