I wanted to find out if the Raspberry Pi supports webcam or not. So I pulled an old Microsoft LifeCam NX-3000 to test with the Pi.The packages were talking a long time to load so I had to perform most of my installation on the emulator instead.
Since my MAC has single hard disk drive, the USB drive for the SD card would always be on /dev/disk1s1 when plugged in. To overcome the problem I created a shell script to write any Raspberry Pi images on the SD card.
#!/bin/bash
sudo diskutil umount /dev/disk1s1
sudo dd bs=1m if=$1 of=/dev/rdisk1
sudo diskutil umount /dev/disk1s1
Through Qemu you can quickly install debian packages on SD card.The image can be loaded on the SD card using the script above.Follow the steps below to test webcam packages on the Raspberry Pi:
1. Remotely access your Linux box using ssh, then mount the folder containing wheezy raspbian image.
2. Create a raw 3GB raw image disk and copy wheezy raspbian onto it:
qemu-img info 2012-09-18-wheezy-raspbian.img
qemu-img create -f raw newwheezy.img 3G
dd if=2012-09-18-wheezy-raspbian.img of=newwheezy.img
3. Start qemu without graphic, and specify 512MB memory (or replace the flag to -m 1024 to use 1GB memory), command:
sudo qemu-system-arm -kernel kernel-qemu -cpu arm1176 -M versatilepb -m 512 -no-reboot -append "root=/dev/sda2" -hda newwheezy.img -net nic -net user -nographic
4. Within qemu emulating Raspbian:
sudo passwd root
(enter new root password: root, twice)
su
(enter root)
aptitude update
aptitude install -y camorama
aptitude show camorama (to make sure it's installed).
shutdown -h now
(enter Ctrl-a x to exit qemu, then quit ssh session to go back to the MAC).
5. From the MAC, use sftp or scp to copy the new wheezy raspbian image loaded with camorama, command:
./loadsd.sh newwheezy.img
6. Now boot your Raspberry Pi with new wheezy raspbian. Enter command: startx to start the GUI & click LXTerminal, enter:
lsub (a list of USB devices is displayed, one of those lines listed the LifeCam)
camorama (command to start camorama, or command cheese to start cheese)

As with all computers, your Raspberry Pi requires a boot-loader and a suitable Operating System to boot. Some Raspberry Pi's comes with pre-installed SD card, but if you didn't receive one you will need to prepare your own.
You can use the BerryBoot installer if your Pi is connected to the Internet.A small zip file containing the BerryBoot system files is required to be extracted to an empty SD card .Then boot up your Pi with the SD card inserted and follow the on-screen prompts to complete the installation. BerryBoot allows you to install more than one Operating System.
To prepare your SD card you have to download the SD image (the data you will write to the card) from a mirror or a torrent . It is recommended that you verify the image with the SHA-1 checksum provided in the download page. After successfully downloading the image extract the image file to a folder of your choice.Now insert the SD card and note the drive letter assigned.Format the SD card to avoid any troubles.You will need an utility (Win32ImageWriter) to make your SD card bootable. Locate the image file that you have extracted and select the drive letter in device box of Win32DiskImager .
Then you need to hit on 'Write' followed by ‘Yes’ when confirmation box appears . The burn process takes around 3 minutes and upon completion you will get a pop up ‘Write Successful’. Now remove the SD card from your computer put it in your Raspberry Pi .You can expand the partitions using configure script to use all of the SD card if you have used SD card of capacity greater than 4 G.B.
