USB modem not found
Last modified: 2014-03-16 22:28:17 EDT
From Bugzilla Helper: User-Agent: Mozilla/4.77 [en] (X11; U; Linux 2.2.19-6.2.16-KRUD-perfctr2.3.6 i586) Description of problem: /usr/bin/neat does not find USB modem. (Modem works in minicom.) Version-Release number of selected component (if applicable): redhat-config-netowrk-1.0.0-1 How reproducible: Always Steps to Reproduce: 1. Run the configuration wizard. 2. Delete all existing modem devices, if any. 3. Shutdown. 4. Plug in USB modem (previously known to kudzu as /dev/input/ttyACM0 c 166 0). 5. Boot, allow kudzu to run. 6. Verify modem appears in /proc/bus/usb/devices. 7. /usr/bin/neat; Add Modem; ==> "No modem found". Actual Results: "No modem found". Expected Results: USB modem configured. (And why does kudzu use /dev/input/ttyACM0, but everyone else seems to prefer /dev/ttyACM0. And why should it matter, as long as /dev/modem is linked to the right place? And if user is allowed to activate/deactivate the device, the the configurator should change the permissions to rw-rw-rw (read and write for every user). Additional info:
redhat-config-network uses kudzu to detect modems.
Additional info: kudzu did detect the modem and configure it at boot. But Network Configuration didn't see it. Modem is Zoom Telephonics 2986 (USB vendor:model 0803:9700)
Essentially the same problem is still there in RHL 8.0 (Psyche). Anaconda sees the USB modem during initial device detection (fresh Workstation install from HardDisk, text mode), although I cannot find a transcript of that to show here [shouldn't it be saved somewhere?]. There is no mention of the modem in /root/anaconda-ks.cfg . The modem appears three times in /etc/sysconfig/hwconf, with different usbclass/usbsubclass/usbprotocol in each appearance. There really is only one modem. - class: OTHER bus: USB detached: 0 driver: unknown desc: "Zoom Telephonics, Inc. 2986L FaxModem" usbclass: 0 usbsubclass: 2 usbprotocol: 1 usbbus: 4 usblevel: 1 usbport: 0 vendorId: 0803 deviceId: 9700 - class: OTHER bus: USB detached: 0 driver: unknown desc: "Zoom Telephonics, Inc. 2986L FaxModem" usbclass: 0 usbsubclass: 0 usbprotocol: 0 usbbus: 4 usblevel: 1 usbport: 0 vendorId: 0803 deviceId: 9700 - class: MODEM bus: USB detached: 0 driver: unknown desc: "Zoom Telephonics, Inc. 2986L FaxModem" usbclass: 2 usbsubclass: 2 usbprotocol: 1 usbbus: 4 usblevel: 1 usbport: 0 vendorId: 0803 deviceId: 9700 - The modem shows in /proc/bus/usb/devices: ----- T: Bus=04 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#= 2 Spd=12 MxCh= 0 D: Ver= 1.00 Cls=02(comm.)
