Question How to create an ISO image from a bootable USB pendrive

I created a bootable usb pendrive with ubuntu netbook remix, and now want to download it to an ISO image to be able to use the pendrive for other purposes, but having possibility to create it again from ISO. What is the right application to do it?

Thanks in advance.

I've only done it from CDs or DVDs, but it should be the same. For XP, for example:

dd if=/dev/hda of=winxpp.iso
You would have to change /dev/hda, of course, that's my DVD drive.

FYI a file with an ISO extension is typically an image of a CD ISO9660 file system. In your case you are creating an image of an entire drive which is not compatible with an ISO image nor can be burned to a CD. The extension is not important. To recreate the USB drive you would use the dd command to rewrite the file back to the device.
