Hi
I'm trying to connect a USB CDMA modem (z010) to a CentOS 4.1
(kernel 2.6.9-11.EL) and I can't talk to the modem. I tried the
same modem under Fedora Core 1 (2.4.22-1.2199.nptl) and it works
like a charm.
The only difference is /dev/ttyACM0 for CentOS and /dev/input/ttyACM0
for the Fedora.
Any help would be appreciated.
Tank's.
