eb1a:5043 eMPIA device driver

[Nicolas Sangouard]

Hi linux-media contributors,

Can someone help me making my video capture device (Masster AVCap) work 
on my linux ? I've never done something like a driver before but I'd 
like to try it now and contribute if it works.

When I plug the device, lsusb says eb1a:5043 eMPIA Technology, Inc.  
which is not on the EM28xx linuxtv.org page.

For information, dmesg says :
