Hi Gerald

Good tip. But this Vendor:Product ID is in the newest version of gspca.
 From the changelog:
Release 01.00.17
	Added basic support vor Pixart PAC7311 based webcams :-), Thomas Kaiser & Joerg 
Schummer
	make:
	0x093a:0x2600, 0x093a:0x2601, 0x093a:0x2603, 0x093a:0x2608, 0x093a:0x260e, 
0x093a:0x260f
	This was a hard, exhausting and very long journey to get this chip working
	The support is not so good: Bad picture quality and not all controls are 
working, but we have at least something
