gphoto2 fails to recognize current Canon S100 with An error occurred in the io-library ('Bad parameters')

[Mark Eichin]

x220t$ gphoto2 -l --debug
finds the camera, and then:

0.090692 gphoto2-camera(2): Listing folders in '/'...
0.090698 gphoto2-camera(2): Initializing camera...
0.090721 context(0): An error occurred in the io-library ('Bad parameters'): No error description available

Turns out this is fixed for 2.5.3 back in July (vs. the 2.5.2 that Saucy includes) though it appears that hasn't shipped yet.

This is, oddly, a regression from raring (which I guess didn't have the listing? and worked fine with this camera by default...)

I don't yet know of a workaround.

(actually, sf/gphoto/958 only fixes the S110, based on looking at svn://svn.code.sf.net/p/gphoto/code/trunk/libgphoto2/camlibs/canon/canon.c r14452, but the same fix is needed for the S100 on line 128 as well (should say 2000 instead of 2001.)

[Mark Eichin (eichin-gmail)]

https://sourceforge.net/p/gphoto/bugs/965/ includes a patch for the S100 case. The attached patch built and worked under Saucy with my own S100 (and includes the S110 case from upstream as well, though I didn't test that.)

The attachment "upstream-r14452-plus-S100-change" seems to be a patch. If it isn't, please remove the "patch" flag from the attachment, remove the "patch" tag, and if you are a member of the ~ubuntu-reviewers, unsubscribe the team.

is the upstream recognition of the fix if anyone is motivated to cherry pick upstream revisions instead.

Status changed to 'Confirmed' because the bug affects multiple users.

Hi,

This bug seems to be closed.

Can someone confirm that ?

regards,

It definitely works for me on Ubuntu 14.04.2 LTS, with my Canon S100. Previously, it didn't work.
