Hey Everyone,

Here's the deal, I've been fighting with this USB Flash Card reader for a while and It just may be I'm missing something simple.

First of all here's my configuration.

Linux 2.4.20

SCSI Emulation - Installed
SCSI Generic Support - Installed
SCSI CDROM Support - Installed ( For my Writer and CD ROM )
USB Mass Storage - Installed
Preliminary USB Devise File System - Installed
UHCI (Intel PIIX4, VIA, ...) support - Installed

Basically if I try to the mount the devices with the following command

mount -t usbdevfs usbdevfs /proc/bus/usb

I can see the devices file and the drivers file and there are 4 other files 001, 002, 003, and 004.

Also there is a directory usb_storage0 in /proc/scsi

When I run a sg_scan -i or just a cdrecord -scanbus, I don't see anything but my CD-Rom Drives. I checked dmesg and here's what the output was.

Manufacturer: SOYO Technologies Corp.
Product: SOYO USB Storage Device
SerialNumber: 0AEC501000001A002
scsi1 : SCSI emulation for USB Mass Storage devices
WARNING: USB Mass Storage data integrity not assured
USB Mass Storage device found at 2
usb.c: usb-storage driver claimed interface dfe12980
usb.c: kusbd: /sbin/hotplug add 2

hub.c: port 1 enable change, status 100
hub.c: port 2, portstatus 103, change 0, 12 Mb/s

So it's finding it, it's just not registering as a SCSI device, when I try to mount /dev/sda1 to a mount point, it tells me:

"Not a valid block device"

Any suggestions on how to get this thing to register as a SCSI device?

Any help would be appreciated.

Thanks

Have you checked your setup against the instructions?
Also, a search on the usb devices web site may add some clues.

Thanks for the Info.

It seems as if I've got everything setup correctly, when I cat /proc/scsi/usb-storage0/1 Here's what I get:
Host scsi1: usb-storage
Vendor: SOYO Technologies Corp.
Product: SOYO USB Storage Device
Serial Number: 0AEC501000001A002
Protocol: Transparent SCSI
Transport: Bulk
GUID: 0aec5010aec501000001a002
Attached: Yes

Thats great and wonderful and all but when I cat /proc/scsi/scsi it just lists my 2 cd-roms, as below:

Attached devices:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
Vendor: BCD Model: F520D CD-ROM Rev: 2.21
Type: CD-ROM ANSI SCSI revision: 02
Host: scsi0 Channel: 00 Id: 01 Lun: 00
Vendor: LITE-ON Model: LTR-52246S Rev: 6S0A
Type: CD-ROM ANSI SCSI revision: 02

I went ahead and recompiled the kernel but this time setting USB-STORAGE as a module. When I rebooted, I ran insmod on usb-storage. Here's what a tail -f message came back with:

Apr 27 22:08:18 anemia kernel: Initializing USB Mass Storage driver...
Apr 27 22:08:18 anemia kernel: usb.c: registered new driver usb-storage
Apr 27 22:08:18 anemia kernel: scsi1 : SCSI emulation for USB Mass Storage devices
Apr 27 22:08:18 anemia kernel: USB Mass Storage support registered.

Grrr.. I just can't figure out why the SCSI emulation is not working correctly.

I still get an invalid block device when trying to mount it.

root@anemia:/proc/scsi# mount -t vfat /dev/sda1 /mnt/flash
mount: /dev/sda1 is not a valid block device

Any help or suggestions would be appreciated!

Thank You

Check the permissions on /dev/sda, and try mounting /dev/sda2 etc..

Hey There,

Permissions are correct, I've even tried mounting as root, still nothing.

For some reason I just don't think the device is linking up on the SCSI layer.
I'm posting this from work so I can't list out my permissions on those devices, but I can assure you that the permissions are correct. At the same time I did try to mount sda1 - sda7 with no success.

Thanks

What version of slackware and what kernel are you running? an updated kernel module may help if it's available.
You may just have a device that just dosn't meet the specs, like some usb modems. This document may provide some hints about that, I like it's title,

Thanks for the link, I'll take a look at it.

I'm running 2.4.20 and Slack 8.1
I'm thinking about enabling DevFS, Not sure if that will do anything, but at this point it's worth a shot.

Thanks for the help, I'll hack at it some more when I get home tonight.
