I noticed in knoppix version 5.1.1 it has a slow down script to read the USB device more carefully and that one works flawlessy on my Dell D820. DSL-3.4 and Knoppix version 3.6 never is able to read the knoppix image. I like Knoppix version 3.6 because it has both 2.4x and 2.6x kernels to choose from.

Here is is:

# All interactively requested modules should be loaded now.

# Give USB-Storage devices some more time to register
if test -d /proc/scsi/usb-storage; then
echo -n "${CRE}${BLUE}Allowing slow USB-devices some more time to register...${NORMAL}"
ash -c "sleep 6"
echo "${BLUE}Ok.${NORMAL}"
fi

# Check for ide-scsi supported CD-Roms et al.
test -r /proc/scsi/scsi && FOUND_SCSI="yes"

I put the before and after script so you know where it is in version 5.1.1 but that is the key I believe that makes 5.1.1 work on all systems. Is it possible to adapt that script to linuxrc file for DSL-3.4?

Maybe that alone will not take care of the problem? I am going to try an older version of DSL to see if that works.

Anyone good with bash scripting let me know what I have to modify in that script in order to try it in the DSL-3.4 linuxrc bash file? Thanks

I have this as a replacement for the wait_usb function in linuxrc and will be available in 3.4.2 and the next dsl 4.

I would rather not penalize everyone with this slow down "sleep 6". But instead leave it as a separate (existing) boot option of "waitusb"

If you wish, just modify the existing wait_usb function on the line

sleep 1

to

ash -c "sleep 1"

See if this works, as it loops and exits when found thus not wating to wait the full count of 6.

If not, then just repace the entire function with the

wait_usb(){
ash -c "sleep 6"
}

Since you have such hardware to test this, it will be great to get your feedback.

First off thanks very much for the reply and suggestions.

I actually tried all four methods changing sleep 1 to sleep 6.

Then modifying the line sleep 1 to ash -c "sleep 1"

Then modifying it to ash -c "sleep 6"

Then finally removing or actually adding #'s to about 6 or seven lines of that wait_usb function and replacing as you said with:

wait_usb(){
ash -c "sleep 6"
}

I basically copied and pasted that. Should there be a space between the () ? Like this ( ) and also a space between () and { ?

Anyhow nothing seemed to help. The kernel boots perfectly and here is what happens:

probing for SCSI....
checking for USB....
Scanning for USB devices.....Done
Enabling DMA acceleration for hdc
Can't find Knoppix filesystem Sorry
Dropping you to a very limited shell

This also happens with Knoppix v3.6 using both 2.4x and 2.6x kernels but does not happen with Knoppix 5.1.1 usb boot so it cannot be the media or device right? It must be some tricky script the Knoppix 5.1.1 has?

Anayhow what can I pass as a cheatcode at the boot prompt:

waitusb ?

Maybe I can try different times?

My system is a Dell Latitude D820 so if you can find someone you know or if you want me to try anything else or even send me a linuxrc file to try please be my guest. Keep in mind this probably will happen to many Latitude D series like the D600 series etc.

Thanks for your help and hope this can be resolved?

Thanks for testing this. I am a little confused by your remark on the cheatcode.

In order to call the wait_usb function you will need to pass the waitusb cheatcode at the initial boot prompt

boot: dsl waitusb

plus any other boot options that you normally need.

Or add waitusb to the append section of your boot loader.

Since I don't have any hardware to test this on, I could only extract out the static ash shell from minirt24.gz and run ash -c "sleep 6" and that worked fine. So, I would think, if the boot option waitusb is used, the actual sleep should occur.

Which I tried before modifying the linuxrc bash script file.

at the boot prompt:

dsl waitusb

Did not help. What else could it be? If I put the initrd image file on the USB it boots fine. However once booted into X if I put another USB stick in and run fdisk -l it does not see the additional inseted usb stick and only the one DSL is on /dev/sda. No /dev/sdb shows up.

So it might be a USB driver issue maybe and not a timing issue?

Ok One final piece of information. I booted DSL using the initrd as the image file and have the dmesg below to see if that can tell you anything but as far as I can see the USB devices are seen but not sure if configured correctly? These are USB ports but I set the Bios to 1.1 compatibility.

dmesg:
