Description of problem:
USB modem is detected and configured at boot in /etc/sysconfig/hwconf,
but kernel module cdc_acm is not loaded, nor is the module listed in
/etc/modprobe.conf. This causes all downstream uses to fail because
/dev/input/ttyACM0 cannot be opened.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. During GRUB boot screen, plug in and turn on USB modem.
Actual Results: kudzu detects and configures modem in
/etc/sysconfig/hwconf, but lists no driver. kudzu forgets to load
kernel module cdc_acm, so attempts to use modem during current boot
will fail until kernel module cdc_acm is loaded manually. kudzu
forgets to put cdc_acm in /etc/modprobe.conf, so future boots [during
which kudzu is quiet because /etc/sysconfig/hwconf is already OK] also
fail because cdc_acm is not loaded.
Expected Results: kudzu detects and configures modem in
/etc/sysconfig/hwconf, and lists cdc_acm as driver. kudzu causes
kernel module cdc_acm to be loaded. kudzu lists cdc_acm in
/etc/modprobe.conf so that modem works OK in future boots.
Similar problem has existed in RedHat distributions for two years.
