USB Storage lost from 2.4 to 2.6 kernal move
 

I have a Fuji FinePix 3800. I've got it jacked to the USB port. It works just fine on my WinsuxXP partition. It works just fine on my Linux 2.4.20 kernel (which I keep now as a backup and install on floppy). Googling for instructions on installing and using this camera, I found I simply needed to run:

mount /dev/sdd1 /mnt/fuji ... and it works like a charm. :)

Now, however, I have the 2.6 kernel. It doesn't work at all. :( Thinking that the rev might be a problem, I tried using 2.6.3, 2.6.5, and now 2.6.6.

I get the same problem. /dev/sdd1 is not a valid mount point. When I ran the 2.6.3 kernel in particular, I rebooted straight into the 2.4.20 kernel (you know, it was just on floppy) and I was able to mount straight to /dev/sdd1. I went right back to 2.6.3 and it's immediately not a valid mount point.

I read that there's no way to locate the mount points except to guess. So I wrote a little code that attempts to mount /dev/sd<d-h><1-5>. It's a sweet little code. But is says that NONE of them are valid mount points. (Here's the code in case you want it...)

>>>
#!/bin/bash

for i in 1 2 3 4 5 6 7 8 9 10
do
echo $i

mount /dev/sdd$i /mnt/fuji
mount /dev/sde$i /mnt/fuji
mount /dev/sdf$i /mnt/fuji
mount /dev/sdg$i /mnt/fuji
mount /dev/sdh$i /mnt/fuji

done
>>>

Should I be looking somewhere else? (/dev/sda,b, and c are taken. I'm a SCSI man.) Is there a library routine that needs to be updated?

Oh, in case you're wondering, I tried having all my USB kernel options set to <M>. But since I got no satisfaction, I set them to <Y>. That includes the USB-STORAGE option too.

I had a similar problem with my disgo USB memory storage, I kept being told that /dev/sda1 was not a valid mount point. The problem was down to my forgetting to enable scsi hard-drive support in the kernel. Maybe that's the problem, that you forgot to include something?

I had the same exact problem. It's a good idea to keep a log of what kernel options to include in your kernel upgrade. I can never remember everything.
:scratch:

well for kernels in the same series, i.e. 2.6.x, just copy the .config for the previous version to the new kernel source folder and make any changes needed from there.

I had a similar problem, running 'modprobe sd-mod' from the command line found the device and mapped it to /dev/sda1

I had some problem with the latest Apacer HT202 pendrive. It seems that the stock partitioning and formatting is not well on Apacer.

Apacer HT202 --> I delete the partition and repartition it using fdisk, format it using WinXP (FAT32)

Apacer Handy Steno 1.1 --> Mac Os X can't load it. Delete the partition in it and repartition it using fdisk. I have 2 partition in this flash drive. A /dev/sda1 -- fat32 /dev/sda2 --ext3.

Thank you guys for the great ideas. However, I've looked for options in my kernel that I hadn't loaded before. I even went and put a few back in because I didn't think I needed them before (like SCSI Generic and LUNs). My system is fully SCSI, so the SCSI part works. I started looking at my /var/log/messages. (I forgot to look before.) It definitely says I'm missing something USB.

NOTE: I changed all USB and SCSI modules <M> to embed <Y> in my kernel. (It hasn't worked at all for the 2.6 kernel...

tailing /var/log/messages:
May 14 21:14:32 harley kernel: usb 2-1: new full speed USB device using address 2
May 14 21:14:33 harley usb.agent[1801]: ... no modules for USB product 4cb/11a/1000
May 14 21:14:33 harley kernel: scsi2 : SCSI emulation for USB Mass Storage devices

Evidently, USB product 4cb/11a/1000 is my camera. And I don't have "modules," per se since the code is embedded in the kernel. But it looks like it found it...

ACK!

I looked at the message I wrote. While I thanked everybody for the great ideas, I didn't explicitly say that it's still broke!

Of note, I can't seem to use my Handspring Visor, either. It gives me a related error about not finding modules for USB product xxx.
