Bug 35624 – libgphoto-2.1.3 no longer supports Canon PowerShot S50

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Steph Gosling 2003-12-11 14:09:32 UTC]

As the summary really. The support seems to have disappeared since 2.1.2-r1:

Using libgphoto-2.1.3:

heroditus root # gphoto2 --list-cameras | grep S50
heroditus root #

Using libgphoto-2.1.2-r1:

heroditus root # gphoto2 --list-cameras | grep S50
        "Canon PowerShot S50 (normal mode)"
heroditus root #

Hunting round bugzilla only turned up #30880 which pertains to an S45, nothing to do with the S50.

The S50 can be used as a Generic PTP device so no problems there.

FWIW:

[Comment 1 Alastair Tse (RETIRED) 2003-12-11 14:21:40 UTC]

the extra ids that was a patch for canon cameras was introduced into the new libgphoto2. seems like some of them have been missed out. 

[Comment 2 Alastair Tse (RETIRED) 2004-01-08 19:35:31 UTC]

i've backported CVS version of canon ids as they were noticed to be missing after the release.

they are now in 2.1.3-r1
