Hi
I am booting from hard disk. USB pendrive inserted before power on.

But, puppy does not detect USB drive and create entry in /dev folder or shows it on the desktop. Since there is no entry, I am not able to mount.

When I scan using pupscan, I am able to see the name of the USB drives, manufacturer and its ID too.

It immediately works if I remove and reinsert. (Since its an automated application, I can't do this)

Now, when pupscan is able to identify the USB drive, why /dev entry is not created?
How can I rescan for USB hardware, so that it can make entry in /dev folder?
Or, is there a forced mechanism to do this?

Thanks a lot for your helps
Eugene

I have no testing available for usb drives but have you tried Startmount and see if it's startup scan detects and mounts it.

See here for pet. You can install, test and uninstall if it doesn't work.

Also, I need to do it in command line. Not on GUI

Hi
Whenever I get x-window not properly shutdown message comes, it detects the USB drive.

Is these the delay time (around 30 secs) it get to initialize? or any other reason?

Xorg versus vesa.

Gparted must show a tick for
Boot ...and ....LBA.....which are most essential.

Try another port at the rear of your computer.

changing ports or display from xorg to other does not solve
I am sure there must be a rescan USB bus utiitym might resolve this issue

Esarch for 'rescan-scsi-bus'.

Well, as one of the writers of the Startmount I meant for you to run it to see if it's scan routines would identify your usb.

Then I would have helped out.

Not now though !!

Hi,

I'm having the same problem, my USB flash drive is not detected at startup, but if I unplug it and replug it in, it then works.

I tried Startmount and it didn't see my flash drive until I un-plugged and re-plugged it in.

This machine is a laptop running Lupu (5.2). It has two USB ports on the right and one on the left. The left one is for my boot USB Flash drive. The right has the non-detected flash drive and also has a USB Wireless LAN that uses NDISWrapper to function. I'll see if I can disable NDISWrapper to see if it has an effect. Does that even make sense to try?

Thanks for the suggestion, but it didn't work.
Any other ideas?

One other piece of information is that I do see the' sdc1' icon in the lower left corner after rebooting, but when I click on it it disappears. So it was seen at some point in the booting process.

Also: I tried booting with PFIX=RAM and it detected the USB Flash drive properly, so it's something I changed or installed.
