Description John Reiser 2002-06-21 19:31:52 UTC
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:

Comment 1 Trond Eivind Glomsrxd 2002-06-21 20:07:30 UTC
redhat-config-network uses kudzu to detect modems.

Comment 2 John Reiser 2002-06-22 05:12:37 UTC
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)

Comment 3 John Reiser 2002-10-05 23:25:12 UTC
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.

From a logged-in X11 console, selecting RedHat > System Settings > Network
brings up Network Configuration.  On the Devices tab, click Add... which brings
up Select Device Type.  Choose Modem connection, click Forward, which results in
 "probing..." then an Warning dialog box "! No modem was found on your system".
