Jamie Bernstein is also using a Novatel EVDO modem and he sent me a work-around
for this bug yesterday:
This command will cause the modem to immediately do its thing (reset?) and
create the /dev/ttyUSB? devices.
eject /dev/cdrom
After entering this command at a terminal prompt (or putting it
into /etc/rc.local if the modem is connected on boot-up) the modem immediately
starts working. No 5 minute wait required.
Therefore, if there is some way that the kernel driver for this modem can issue
a similar "reset" command, the problem may go away.
I have added a note about this to the bug report at:
https://bugzilla.redhat.com/show_bug.cgi?id=473166
I am glad to hear you have it working.
Maybe a HAL rule to eject the SCSI device the Novatel as soon as it
is detected? Or a udev rule that does the same thing? Just as a
temporary fix? If I remember right, it has different device IDs in
drive and modem modes.
