Notes for configuring udev rules for em28xx USB capture card

Goal: 
to create static /dev/video10 for plug in USB capture device em28xx.  Static video card location using udev rules ensures that the correct video device is utilised during reboots.  Used for motion program www.lavrsen.dk

Soloution: 
auto create a symlink from kernel assigned video address to /dev/video10 when em28xx is plugged in.

Plug in device and note video number assignment i.e. video0
then use this command to search for variables that can uniquely identify this device.
udevadm info -a -p $(udevadm info -q path -n /dev/video0)

Create udev rule:
KERNEL=="video[0-9]*", DRIVERS=="em28xx", SYMLINK+="video10"

Where:
KERNEL=="video[0-9]*" binds this rule to only video devices
DRIVERS=="em28xx" bind the rule to devices using driver em28xx
SYMLINK+="video10" creates a symlink from /dev/videoX to /dev/video10

Does it work:
ls /dev/video*

sudo service udev restart

Motion webcam two webcams change order on boot /dev/video0 persistent linux ubuntu

Copied from various resources on the web, Original Reference Here

When using Motion http://www.lavrsen.dk/foswiki/bin/view/Motion with multiple usb webcams, sometimes the dev order of the webcams changes on reboot of a machine. 

i.e.  /dev/video0 becomes dev/video1

This can seriously stuff things up.  To overcome this, create a udev rule to lock/assign a device dev location.

First do a lsusb, notice that I have two webcams, one is built into the screen and the other is USB connected.

Take note of the ID of the webcam you want
i.e 045e:00f7


Now do a:
sudo touch /etc/udev/rules.d/25-name-video-devices.rules


Edit this file and enter the following:
SUBSYSTEM=="video4linux", BUS=="usb", SYSFS{idVendor}=="045e", SYSFS{idProduct}=="00f7", NAME="video5"


I assigned the webcam to give a default location of /dev/video5 so it would never conflict with other webcams fitted in the future (hopefully)

Don't forget to modify your ~/.motion/motion.conf file and change the video device to /dev/video5


What happens if you have two webcams and they are both the same?  Fuuuuuuuuuuuuuuuuu!!!!!!!!!!!!!!!

Testing fake USB Flash Drives with H2testw

Fuck those pricks that want to rip people off, selling fake drives on eBay.  Some people buy these cheap drives on ebay without knowing that they could be fake.

Using H2testw program is the simplest way of testing your flash drive.  You just download the zip and run the executable on a windows crap box.
Direct download

FAIL!

If you have a failed drive, you should try to get your money back from the person who sold it to you and chuck the drive out!

No Problems experience here. 

• Plug in the USB connection
• Hit 'back' to get out of the data storage screen
• Go to settings > Wireless & networks > Tethering & portable hotspot > USB tethering

The bonus here is that the tablet will be charged from the USB port while you are surfing using your laptop and you can surf the web on the tablet while tethered.
