Creating bootable USB on a Mac - is the dd command working?

Hi, I’m a new user and trying to create my first bootable USB on a Mac, want USB rather than CD because I also hope to install it on my new ASUS EEE PC. I’ve successfully navigated the instructions to download openSUSE and prepare the USB (unmount), but have run # dd if=/path/to/downloaded.iso of=/dev/diskN bs=4k in Terminal and its now unresponsive (the user$ hasn’t reappeared). The instructions (SDB:Live USB stick - openSUSE) mentioned it should ask for an administrator code but it didn’t, I’ve waited around two hours and presume it should have written the file by now? Last command was Tim-and-Jesss-iMac:~ JessandTim$ dd if=/Users/JessandTim/Downloads/openSUSE-12.1-DVD-x86_64.iso of=/dev/disk1 bs=4k - am I missing anything simple here? Not sure what to do, any advice appreciated, thanks!

For anyone else who has this issue. It worked fine, just never asked for the password and took a few hours

So you may be good, but another resource for LiveUSB creating is a bash script I have written you can find here:
