Hi there,

I'm new to this forum, and I hope this is the right place to ask for help with this issue. I've been searching for a solution to this for a long time now without luck.

Background info on my system
- Quantian 0.6.9.2 hard disk installation. This is a knoppix 3.6 based distro.
- Kernel 2.6.9 with usb-storage enabled.
- Lexar Media jump drive
- Nikon Coolpix 885 digital camera

Both the camera and the jump drive are recognized fine when plugged-in prior to a CD based boot-up. That is, both work fine when the original distro runs from the CD. They do not work when running from the hard drive installation. See below.

Problem
- lsusb shows my Lexar jump drive and my camera are being recognized by the system (I use a USB hub):

Bus 002 Device 005: ID 04b0:0105 Nikon Corp.
Bus 002 Device 004: ID 05dc:a400 Lexar Media, Inc.
Bus 002 Device 003: ID 0c45:6029 Microdia Triplex i-mini PC Camera
Bus 002 Device 002: ID 058f:9254 Alcor Micro Corp. Hub

- lsmod shows:

- When attempting to mount the jump drive, for instance, I get the error:

mount: /dev/sda1 is not a valid block device

I've tried mounting from other sd* devices in case they were assigned to another number, but nothing changes.

I'd be very grateful for any pointers, as I'm very stuck with this problem.

Thanks in advance! and hope to see you at the next meet-up,

let's just stop and look at what is actaully happening when each device is connected. so... unplug device. run "dmesg -c". plug in device. run "dmesg" that second output will contain everything the subsystem did to handle your device.

from your module list, i see no refernce to sd_mod or a filesystem liekly to be on the device, e.g. fat. these may have been built into your kernel though.

Thanks for responding. The output of dmesg -c after unplugging the devices is too large to post, but here are the lines at the end that seemed relevant to me:

usb 2-1.2: USB disconnect, address 4


Please see the next message for the dmesg after plugging back the jump drive. I'm recharging the battery of the camera now

hmmm...., this "post-replugging" dmesg looks strange:

24.77.68.1 sent an invalid ICMP type 3, code 3 error to a broadcast: 24.77.71.255 on eth0

usb 2-1.2: new full speed USB device using address 6
usb 2-1.2: not running at top speed; connect to a high speed hub
uba: device 6 capacity nsec 252928 bsize 512
uba: was not changed

The strange thing is that I have working webcam connected to the same hub, AND all three devices (webcam, digital camera, and jump drive) work fine when I run knoppix from the CD. Quantian (Knoppix) does a great job of recognizing everything on boot-up, but the hard disk installation is having trouble somewhere.

In anticipation, here is my /etc/fstab, which I've modified slightly after the hard disk installation (SPL entry):

Hi

Boot your computer, unplug the drive
Plug it back in and try to mount it
What happens?

Sls

For me it looks more like an issue with ub (Low-performance USB-Blockdevice), look at the ub module loaded and the output from dmesg about what happens when drive is connected:The important thing here is the uba: messages, but with usb-storage one whould expect something like this:Just removing it from loaded modules or /lib/modues/`uname -r`/ will not help too much because activating that module at configuration time has at least effects on usb-storage! So recompiling kernel is needed here.

bonbons seems to be right on target here, have a look at the bottom of this page:

http://www.cs.utexas.edu/users/suriy...migration.html

I'm recompiling tonight and will post a report later. Thanks to all for your help so far!

I compiled Linux kernel 2.6.11.6 last night and confirmed that enabling the option BLK_DEV_UB (Block Devices -> "Low performance USB block driver") cripples the usb-storage driver, as the help in xconfig says. I hadn't been careful reading this when compiling my previous 2.6.9 kernel!

So I was able to login with my new 2.6.11.6 kernel, but only in console mode. For some reason kdm doesn't want to start. I've tried 'su -c "kdm"', but the console goes blank for a second and returns to console mode. I don't remember having this problem last time I compiled the kernel. What could I be missing here?

Thanks
