USB Mass Storage
 

I've read a thread named USB Mass Storage from this forum on google, and as I have
a similar problem which that didn't help with, here's hoping someone can help me!

I have a Neo25IV, otherwise known as an mstation, it's an MP3 player and USB
mass storage device.

If I connect it to a RH9 box with 2.4.21 kernel, I get
Aug 2 07:42:35 notorious kernel: hub.c: new USB device 00:04.2-1, assigned addr
ess 2
Aug 2 07:42:35 notorious kernel: Manufacturer: ScanLogic USBIDE
Aug 2 07:42:35 notorious kernel: Product: ScanLogic USBIDE
Aug 2 07:42:35 notorious kernel: usb.c: USB device 2 (vend/prod 0x4ce/0x2) is n
ot claimed by any active driver.

(I have usb debugging set in the kernel, so there's heaps more if anyone wants it!)


/proc/scsi/scsi has
Attached devices:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
Vendor: Model: Rev:
Type: <NULL> ANSI SCSI revision: ffffffff

So it looks like it finds it, but needs info about it.

I've tried updating firmware as per the linux-usb.org info, but that didn't seem to make
any difference.

after a minute or so it says:
Aug 2 07:43:08 notorious kernel: usb-uhci.c: interrupt, status 3, frame# 1307
Aug 2 07:43:08 notorious kernel: scsi: device set offline - not ready or comman
d retry failed after bus reset: host 0 channel 0 id 0 lun 0


I believe there's a file somewhere you can edit to add info about a device if the kernel
can't work it out by itself, anyone have any idea where that is? And anyone have any idea what info should go in there for this device?

Any clues as to what I can do? Maybe I grabbed the wrong firmware?
Aug 2 07:42:35 notorious kernel: Device version = 2.60
is what I get.

The linux-usb mailing list has been resoundingly silent, I'm hoping someone here can help...

I don't know if this could help but its worth a shot

I have a usb card reader/writer (6 in 1 iwill) and last week i tried to configure it and was successfull in mounting it as an ordinary drive and here is wat i did:
1st: compile the kernel with
---SCSI---
<M> SCSI support
--- SCSI support type (disk, tape, CD-ROM)
<M> SCSI disk support
(40) Maximum number of SCSI disks that can be loaded as modules
< > SCSI tape support
< > SCSI OnStream SC-x0 tape support
<M> SCSI CD-ROM support
[ ] Enable vendor-specific extensions (for SCSI CDROM)
(2) Maximum number of CDROM devices that can be loaded as modules
<M> SCSI generic support
--- Some SCSI devices (e.g. CD jukebox) support multiple LUNs
[ ] Enable extra checks in new queueing code[*] Probe all LUNs on each SCSI device
[ ] Verbose SCSI error reporting (kernel size +=12K)
[ ] SCSI logging facility

---USB---
<M> USB Mass Storage support
[ ] USB Mass Storage verbose debug
[ ] Datafab MDCFE-B Compact Flash Reader support

off course dont forget to compile the necessary usb module for USB host controller

2nd: boot to the new kernel
load the modules just to make sure with insmod/modprobe
monitor your /var/log/messages. my log file shows up
Aug 2 11:50:18 flip kernel: scsi1 : SCSI emulation for USB Mass Storage devices
Aug 2 11:50:18 flip kernel: sda: I/O error: dev 08:00, sector 0
Aug 2 11:50:18 flip kernel: sdb: I/O error: dev 08:10, sector 0
note: there is an error because i dont have any flashcard pluged in the device
now im able to mount my devices and they are assigned to /dev/sda1, /dev/sdb1 ... etc
make sure that the modules sd_mod, sg, sr_mod, usb-storage loaded.

good luck
ps. dont forget to umount it before removing the device so that the changes you made to the file system will be made after any writing on it

I also have a USB 6-1 card reader. I have been unable to make it work. Here is a portion of my /var/log/messages

I am not able to mount the device or perhaps I don't know how. I created a directory in /mnt called camera.
I have tried "mount -t vfat /mnt/sda1 /mnt/camera"
and "mount -t auto /mnt/sda1 /mnt/camera"

I should also say that there is no /sda in /dev

I don't really know what I'm doing. I've read lots of snippets about it but never a really good explaination. I am using Mandrake 9.1.

Thanks,
