Stk1160 based USB 2.0 video and audio capture devices
This article covers all the devices which are based on the STK1160 chip
Many but not all of these devices are branded as Easycap.
How to identify your device
When lsusb reports the following output you have an STK1160 based video capture card:
Bus 001 Device 002: ID 05e1:0408 Syntek Semiconductor Co., Ltd STK1160 Video Capture Device
The easycap driver is part of the current kernel (since 2.6.38) and supports all the features of the STK1160 based devices but has some limitations (framedropping, stability, sound issues)
The stk1160 driver is the successor of the easycap driver. It supports video capturing and audio capturing via ALSA. This driver doesn't suffer from the limitations of the easycap driver but is still under development. It is intended that the stk1160 module will replace the easycap module in one of the next kernel releases. Source code for kernel 3.2:  Installation instructions: 
Short linux driver history
In early 2010 Mike Thomas started to develop a driver for the stk1160 based video capture device which is sold as EasyCAP DC60. Since the driver has been added to the kernel release in November 2011 Mike Thomas stopped the development and support of the easycapdriver.
