Running Knoppix 3.8.2 installed on hard drive, Pentium 600, 50GB hard drive, networked. Some minor problems (posted elsewhere).

I connected a USB hub (externally powered) and Linux sees it, no problem. If I connect my mouse via it, rather than direct, the mouse works fine. I conclude the hub is OK.

However, I cannot get Linux to work with digital camera, my webcam, or a pen drive when connected via the hub or direct.. All three appear in USB viewer, with their details. I can't copy and paste the detail that shows (USB Viewer won't do that).

I tried for the pen drive "mount -t vfat /dev/sda1 /mnt/usbdrive" and got the answer "dev/sda1 is not a valid block device."

I don't know the equivalent commands for the webcam or the Pentax EI-200 (which is the same as the HP Photosmart 61.

What should I be doing to get these three devices to work with Knoppix-on-HD?

PS: I tried to install usbmount via Kpackage, and got the following response (several times):

< export DEBIAN_FRONTEND; apt-get install --yes 'usbmount' ;echo RESULT=$?

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.

Since you only requested a single operation it is extremely likely that
the package is simply not installable and a bug report against
that package should be filed.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
usbmount: Depends: udev (>= 0.053-1) but it is not going to be installed
E: Broken packages
