Most recent kernel where this bug did not occur: vanilla 2.6.22 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 usbcore: registered new interface driver option drivers/usb/serial/option.c: USB Driver for GSM modems: v0.7.1 Other relevant information: dmesg | grep -i scsi SCSI subsystem initialized scsi0 : ata_piix scsi1 : ata_piix scsi 0:0:0:0: Direct-Access ATA TOSHIBA MK1637GS DL03 PQ: 0 ANSI: 5 sd 0:0:0:0: [sda] Attached SCSI disk scsi 1:0:0:0: CD-ROM HL-DT-ST DVDRAM GSA-T20N WT03 PQ: 0 ANSI: 5 sr0: scsi3-mmc drive: 24x/24x writer dvd-ram cd/rw xa/form2 cdda tray sr 1:0:0:0: Attached scsi CD-ROM sr0 scsi2 : SCSI emulation for USB Mass Storage devices scsi 2:0:0:0: CD-ROM HUAWEI Mass Storage 2.31 PQ: 0 ANSI: 2 sr1: scsi3-mmc drive: 0x/0x caddy sr 2:0:0:0: Attached scsi CD-ROM sr1 LUN scan shows HUAWEI as type "cdrom" again: /etc/rc.d/rc.scanluns Scanning all LUNs for additional hardware: /sbin/rescan-scsi-bus -l Host adapter 0 (ata_piix) found.
