What does # /usr/sbin/kudzu -p -c "MODEM" print? Created attachment 94118 [details]
/usr/sbin/kudzu -p -c "MODEM"
Obviously the PCI Winmodem should be ignored, and the USB FaxModem should be
recognized.
Kernel modules acm and usbcore were already loaded at the time of "kudzu -p -c". (I believe that they were loaded by kudzu at boot; the USB modem was connected and powered up before, during, and after boot.) still an issue? Yes, a USB modem still cannot be found. Desktop > Settings > Network; New > Modem connection > Forward still gives "system-config-network: No modem was found on your system." This was after turning on a USB modem that was plugged into a previously-running system (i.e., "hotplug" situation, as opposed to "cold plug" which is plugged in and turned on before boot.) The "Select Modem" dialog box presents /dev/modem as the default choice, and (among others) /dev/input/ttyACM0 is listed in the drop-down list. [Notice the extra "/input" in the name.] From /var/log/messages: ----- Jul 8 09:07:34 fc4final kernel: usb 5-2: new full speed USB device using uhci_hcd and address 3 Jul 8 09:07:35 fc4final kernel: usb 5-2: configuration #2 chosen from 2 choices Jul 8 09:07:35 fc4final usb.agent[4550]: Keeping default configuration with /sys//devices/pci0000:00/0000:00:1f.4/usb5/5-2 Jul 8 09:07:39 fc4final kernel: cdc_acm 5-2:2.0: ttyACM0: USB ACM device Jul 8 09:07:39 fc4final kernel: usbcore: registered new driver cdc_acm Jul 8 09:07:39 fc4final kernel: drivers/usb/class/cdc-acm.c: v0.23:USB Abstract Control Model driver for USB modems and ISDN adapters ----- /sbin/lsmod shows (selected lines): ----- cdc_acm 13409 0 uhci_hcd 35152 0 ohci_hcd 26849 0 ehci_hcd 41037 0 ----- /dev contains [newly]: crw-rw---- 1 root root 166, 0 Jul 8 09:07 ttyACM0 So it looks like hotplug worked (/dev/ttyACM0 got created, kernel module cdc_acm got loaded and initialized), but the association between that and a Network device (either a symlink /dev/modem -> ttyACM0, or the recognition of /dev/ttyACM0 as a likely modem device) did not get made. The component versions are now FC4 final release: kernel-2.6.11-1.1369_FC4 system-config-network-1.3.26-1 hotplug-2004_09_23-7 hal-0.5.2-2 kudzu-1.1.116.2-2 Red Hat apologizes that these issues have not been resolved yet. We do want to make sure that no important bugs slip through the cracks. Red Hat Linux 7.3 and Red Hat Linux 9 are no longer supported by Red Hat, Inc. They are maintained by the Fedora Legacy project (http://www.fedoralegacy.org/) for security updates only. If this is a security issue, please reassign to the 'Fedora Legacy' product in bugzilla. Please note that Legacy security update support for these products will stop on December 31st, 2006. If this is not a security issue, please check if this issue is still present in a current Fedora Core release. If so, please change the product and version to match, and check the box indicating that the requested information has been provided. If you are currently still running Red Hat Linux 7.3 or 9, please note that Fedora Legacy security update support for these products will stop on December 31st, 2006. You are strongly advised to upgrade to a current Fedora Core release or Red Hat Enterprise Linux or comparable. Some information on which option may be right for you is available at http://www.redhat.com/rhel/migrate/redhatlinux/. Any bug still open against Red Hat Linux 7.3 or 9 at the end of 2006 will be closed 'CANTFIX'. Again, if this bug still exists in a current release, or is a security issue, please change the product as necessary. We thank you for your help, and apologize again that we haven't handled these issues to this point. This problem still exists in Fedora Core 5. System > Administration > Network; New > Modem connection > Forward; "No modem was found on your system." The USB modem was cold-plugged (plugged in and powered on before boot; at boot, udev caused activity in modem lights; modem lights showed Ready.) Say OK to the message; the drop-down list defaults to /dev/modem which does not exist. The drop-down list also contains /dev/input/ttyACM0, which is incorrect (should be /dev/ttyACM0 with no "input/".) Kernel module cdc_acm was loaded automatically, as shown by "/sbin/lsmod". The modem is listed in /proc/bus/usb/devices. /var/log/messages contains ----- Aug 5 07:10:08 farmer kernel: usbcore: registered new driver cdc_acm Aug 5 07:10:08 farmer kernel: drivers/usb/class/cdc-acm.c: v0.25:USB Abstract Control Model driver for USB modems and ISDN adapters ----- as a boot-time message (before invoking system-config-network.) -----/etc/sysconfig/hwconf class: OTHER bus: USB detached: 0 desc: "Zoom Telephonics, Inc.

patch to./src/netconfpkg/NC_functions.py
This patch appears to fix the problem: no complaint about "Modem not found",
and rest of configuration proceeds normally, without even asking about where
the modem is.
Fedora Core 5 is no longer maintained. Is this bug still present in Fedora 8? Works in F8 with: system-config-network-1.4.7-1.fc8 NetworkManager-0.7.0-0.6.7.svn3235.fc8 |
