I do command "svn log" and in r170 ------------------------------------------------------------------------ r170 | pinchartl | 2008-01-18 08:13:21 +0800 (Fri, 18 Jan 2008) | 8 lines Add EOF sync quirk and use with Syntek 174f:5212 The Syntek 174f:5212 UVC camera in HP Spartan laptops doesn't toggle the FID bit. This patch adds a quirk to synchronize on the EOF bit only. Thanks to Claudio Matsuoka and Herton Ronaldo Krzesinski from Mandriva for reporting the issue and submitting a first patch proposal. ------------------------------------------------------------------------ > > > > I try the Syntek case and find it can work. > > Ok, since you say the camera doesn't work without the quirk I will make > sure it is added. > > Cheers, > > Brandon > > > On Fri, Feb 15, 2008 at 2:31 PM, Brandon Philips <[EMAIL PROTECTED]> > wrote: > > > On 13:37 Fri 15 Feb 2008, Albert Chuang wrote: > > > > Oh, I maybe understand your statements. > > > > Do you mean that it should work if the camera is a normal UVC device > ? > > > > But I try the genesyslogic camera it seems to need the > > > > UVC_QUIRK_STREAM_NO_FID. > > > > > > Ok, if you tried the device without UVC_QUIRK_STREAM_NO_FID and it > > > didn't work then the entry is needed.
