usb devices not seen in Knoppix V4.02

**Jbike** · 12-05-2005, 01:31 PM

Knoppix V4.02 When I install a usb device, I do not get an icon on the desktop, or any way of accessing the files, however if you open System Kinfocenter and highlight usbdevices, I get a confirmation that the system knows all about my jumpdrive, down to the mfg and model number. In another forum, there was instructions on how to fix this by loading the ehci_hcd (ehci-hcd), however this file could not be found (not where the author said it would be). Does anyone know how I can fix this so that I can see my flash drives?

Thank you

I just downloaded 4.0 and have little experience with it. So, I am not much help on your problem.

However, let us first eliminate possible solutions.

Put your flash drive in the USB place when you boot up.

Open a terminal, type su <enter> to change to root mode.

type mkdir /mnt/removable

But, first see if it has /mnt or /media, change command accordingly.

Then, type something like (google if not correct, my time here is limited) mount /dev/sda1 /mnt/removable

Then click on /mnt/removable and see if it takes.

If you have tried this already, then I have no ideas. Sorry. I do know in general on Live CD's I have had to do this, though I think on one, forgot which, sda1 was mounted automatically.

since you obviously have some kind of communication with the USB device, you can always mount it yourself. All you have to do is

Code:

 mount /dev/sda /mnt/removable

or to some other mount point on your machine. You will likely have to do this as root. As a more permanent solution, make sure your /etc/fstab file contains something like

Code:

/dev/sda /mnt/removable auto defaults 0 0

.

Thanks for the help. After making a /mnt/removable directory, and modifying my fstab file (as root), I can now see my usb data. However.... I still have to open a shell, log in as root, and type mount /dev/sda1 /mnt/removable in order for the usb drive to pop up on my desktop. All my data is there. The right click unmount command does not work, and complains that I need to be root.

Does anyone know how to make the modifications such that any users other than root can use removable media? Perhaps by locating my /mnt/removable in a user directory? Also, in other distro's and in V3.9 and lower in knoppix, the desktop usb stick icons simply appear and disapear when the media is installed or removed, without any textual shell mounting. Does anyone know how this is done?

Thanks so much.

Try adding after auto in /etc/fstab ",uid=username,gid=groupname (substituting your username and groupname or number - probably 1000) and see if that does the trick.
