Bug 1723

Distribution: gentoo/ppc 1.4 (current rsync'd at dec 12 6:42pm PST)
Hardware Environment: G3 PPC 266Mhz
Software Environment: ? gentoo/ppc ?
Problem Description: USB Mass Storage/IOMEGA Zip Complete Fail.
More Info: I'm currently using USB mouse, printer and keyboard with no problem
whatsoever. 

Steps to reproduce:
use .config below... and try to mount IOMEGA USB Zip through /dev/sda (which
should actually show up as /dev/sda1 or /dev/sda4, right??)

I want to preface this by saying I've posted this on many lists, forums and
so on... I'm only resorting to the developers because I've exahusted all
other resources........ The following is the post that I put to my distrobutions
forum....
But first my stats:
Gentoo/PPC
266Mhz G3 PPC
USB Keyboard: working
USB Mouse: perfect
USB Printer: works
Kernel: 2.4.22 also trying 2.6.0 and 2.6.0-test11

IF YOU WANT MORE ERROR MESSAGES/LOGS or dmesg OUTPUT PLEASE LET ME KNOW...
I'm willing to work with anybody who has any idea what iis wrong....
(guerrilla_thought(at)gmx.de)

Okay. I've recompiled the kernel litterally DOZENS of times... This is
insane!
I can to get my USB Zip drive to work no matter what I do. I've got hotplug,
usbutils, I've got usb-mass storage, scsi (and scsi ide emulation)

I should mention I've tried on the 2.6.0 and 2.4.22 kerels. I've tried both
vfat, msdos and hfs filesystems.

"/dev/scsi/host2/bus0/target0/lun0: I/O error: dev 00:00, sector 0"

at the moment there is no /dev/sda1 or 2 or 3 or 4... only /dev/sda
fdisk /dev/sda says it can't open it. Sometimes when I put a disk into the
zip drive it makes loud disk spinning noises repeatedly, over and over and
over... (this is only supposed to happen once) ive researched on google and
all
that and i really am at a loss.

Okay.. I do have OHCI (and UHCI)
heres part of my .config
Code:

CONFIG_USB=y
CONFIG_USB_DEBUG=y
CONFIG_USB_DEVICEFS=y
CONFIG_USB_UHCI_ALT=y
CONFIG_USB_OHCI=y
CONFIG_USB_STORAGE=m
CONFIG_USB_STORAGE_DEBUG=y
CONFIG_USB_PRINTER=y
CONFIG_USB_HID=y
CONFIG_USB_HIDINPUT=y
CONFIG_USB_SERIAL=m


Like I said before, everything that is a module, has at one point or another
also been tried as an in-kernel.

I know for a fact that USB works because my (this)keyboard, mouse and
printer (which all work) are USB.

And heres my SCSI


Code:

CONFIG_SCSI=m
CONFIG_SCSI_DEBUG_QUEUES=y
CONFIG_SCSI_MULTI_LUN=y
CONFIG_SCSI_CONSTANTS=y
CONFIG_SCSI_MESH=m
CONFIG_SCSI_MESH_SYNC_RATE=5
CONFIG_SCSI_MESH_RESET_DELAY_MS=4000


and all of these have been tried as in-kernel and module.
note too that MESH is low-level driver SCSI for my PPC.
I also have IDE SCSI emulation as M and at other times in-kernel as wel...
Ok here are some more error messages I found.. I'm still hunting for more in
my logs






Code:

usb-storage: Bad target number (4/0)
usb-storage: *** thread sleeping.
usb-storage: queuecommand() called
usb-storage: *** thread awakened.
usb-storage: Bad target number (5/0)
usb-storage: *** thread sleeping.
usb-storage: queuecommand() called
usb-storage: *** thread awakened.
usb-storage: Bad target number (6/0)
usb-storage: *** thread sleeping.
usb-storage: queuecommand() called


These repeat themselves forever (a while at least).

here are some errors from /var/log/kernel/current

Code:

Dec 20 01:17:52 [kernel] scsi2: ERROR on channel 0, id 0, lun 0, CDB: 0x28

Dec 20 02:06:13 [kernel


and that actually goes on forever until i disconnect the drive and/or unload
the modules.... At one point I had a 9MB log file/directory....

and just for reference this is mounts output:

Code:

# mount /dev/sda /mnt/usbzip -t hfs
mount: wrong fs type, bad option, bad superblock on /dev/sda,
       or too many mounted file systems


or plain
Code:

#fdisk /dev/sda
Unable to read /dev/sda


And I want to also note that during all of thise the light on the zip drive
does blink. And often it makes spinning noises ad infinutm.

I also want to note I tried the patch for (submitted to
linux-usb-devel@lists.sourceforge.net) to
/usr/src/linux/drivers/usb/storage/transport.c
I also tried commenting out that section of code.

I don't know why I bothered with the patch above, but I'm getting severly
desperate.....

If you are interested the below URL's are from my distrobutions (Gentoo) forums.... 

http://forums.gentoo.org/viewtopic.php?t=107764&postdays=0&postorder=asc&highlight=usb+mass+storage&start=0




Anyway... Thanks for any help you can give...... I'll keep digging on
google, forums and other lists too....
If anyone at all can help me with this I'd soooo appreciate it.... I just am
running out of things to try... This is insane...,.
