Re: Trust WB-1300N webcam

[Thomas Kaiser]

Hello Tommy

I forward this mail to the v4l mail list because gspca V1 (spca5xx) is 
deprecated.

New, gspca V2 (v4l2 interface) is part of the official kernel tree, now. 
The newest source is included in the linuxtv project (www.linuxtv.org).

Jean-Francois, can you please pick up these changes?

Regards, Thomas

PS: Tommy, subscribe to the v4l mail list to get more infos about the 
progress with gspca v2.
