From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.6) Gecko/20040510 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): kudzu-1.1.62-1 How reproducible: Always Steps to Reproduce: 1. During GRUB boot screen, plug in and turn on USB modem. 2. Boot. 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. Additional info: Similar problem has existed in RedHat distributions for two years. See bug 100503 and bug 98790. Contents of /etc/sysconfig/hwconf will be attached.
