I think this was supposed to be "not known"..  It is unclear.

Of cause, it is "not known". Sorry folks.<br>

    <pre wrap="">Distribution: Slackware 12.0
Hardware Environment: HUAWEI USB modem E220 on Intel 82801G (ICH7) USB2 EHCI;
Intel 82801G (ICH7) PCI Express
Software Environment: SCSI
Problem Description: The HUAWEI USB modem includes a mass storage device to
access the modem's built-in ROM. The kernel's SCSI environment (see relevant
dmesg below) incorrectly initializes that mass storage device as a CDROM on
/dev/sr1, which causes three known symptoms:

1) "/etc/rc.d/rc.hald start" removes /dev/sr1 until udev puts it back. This
means that the modem gets initialized twice every time I boot Linux.
Workarounds: (i) do not start hald, or (ii) attach the modem after hald has
initialized.

2) k3b device scan also removes /dev/sr1 and if I am unlucky and have pppd
already running, pppd gets terminated as well. Workaround: "chmod 000 /dev/sr1"
or "chgrp root /dev/sr1" (Slackware udev initializes /dev/sr1 as group cdrom).

3) Warnings from module "option":
dmesg | grep -i option
option: Unknown symbol usb_serial_port_softint
option: Unknown symbol usb_serial_disconnect
option: Unknown symbol usb_serial_probe
option: Unknown symbol usb_serial_register
option: Unknown symbol usb_serial_deregister
option 3-1:1.0: GSM modem (1-port) converter detected
option 3-1:1.1: GSM modem (1-port) converter detected
