How my webcam works everytime in Fedora

It's not a new problem for me, from f-11 I use same method to make my laptop webcam works, I found it long back after too much google and saved those steps as mail drafts.(Without those steps, cheese not detect my laptop webcam)

$ su
# yum install hgsvn
# yum install libusb-devel
# exit
$ hg clone http://bitbucket.org/ahixon/r5u87x/
$ cd r5u87x
$ make
$ make rules
$ su
# make install
# ./loader
# modprobe -r uvcvideo
# modprobe uvcvideo
# exit

According to my understanding r5u87x is my webcam driver which not install default in fedora, modprobe first remove old module of uvcvideo and update latest one (after changed), Please correct me if I am wrong. But I really wanted to know why those stuff is not available as default.

Beefy Miracle Beta Review

Installation Adventure
Well this Thursday I made my mind to install beta release of f-17. I had to make a boot able usb because my dvd drive gave up long back. So I used livecd-tools to make bootable usb. I started installing, it was going smoothly but suddenly I got notification for access Network for installing repo .. bad ah because you screwed :). Later found out there was bug in livecd-tools :(, even fedora wiki was not updated about use of livecd-tools that time (Now updated, thanks to FranciscoD). Well I install fedora in my office laptop VM, made again usb bootable with correct steps and finally able to Install.

Few Observation
1. Now grub-2 is there, during booting you can chose Advanced Options for rescue purpose.
2. Gnome-3.4.0, with some new features like documents, improved contacts app, improved system settings any many more ..
3. My Airtel 3G modem worked out of the box :)
4. Now mounted drive are no longer under /media, it's now /run/media/<username>

Few Defects
1. My laptop camera is still not working (will file bug soon)
2. when xchat is open and you restart gnome-shell then xchat notification will disappear from notification area.
3. Whenever I switched off wireless using toggle button and turned on again it's showing <hardware disabled>, after reboot it works again but if I do again same action then again show same error. Seems like a bug.

Till now everything else working smoothly, will update if something come up :)
