Description John Reiser 2003-06-08 09:33:30 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0.0) Gecko/20020529

Description of problem:
/usr/bin/minicom says "cannot open /dev/modem: No such device" under
kernel-2.4.20-7 (RHL7.3); it works under 2.4.18-27.7 (RHL7.3) and 2.4.20-8
(RHL9).  Here /dev/modem -> usb/ttyACM0 [or input/ttyACM0] and permissions are
0666 (allow everybody).  When it fails, then /sbin/lsmod shows that module acm
is missing, and an explicit load of module acm enables minicom to open the modem.

Intel 845 chipset, 5 USB hubs (2* usb-ohci, 2* usb-uhci, 1* ehci-hcd).

I will attach output from
   dmesg
   /proc/bus/usb/devices
   /proc/interrupts
   lspci -vv
for each kernel.

Version-Release number of selected component (if applicable):
kernel-2.4.20-18.7

How reproducible:
Always

Steps to Reproduce:
1.boot.
2./usr/bin/minicom
3.
    

Actual Results:  minicom: cannot open /dev/modem: No such device


Expected Results:  [minicom opens modem with no complaint.]

Additional info:

There may be some relationship to bug 91041 or bug 92417.
