Logitech C615 - Only supports low resolution?

Hey there, I have a question about the available resolutions on my Logitech C615 camera.

I'm currently running Linux Mint 18 Cinnamon 64 bit, and I'm able to access my camera under /dev/video0, however only at low resolutions.

When I use the settings of: YUYV, I'm forced to use 176x144, and if I switch it to MJPEG, I can achieve 640x480. I'd like to be able to use 1280x720 for this camera as I've done with my windows installation using iSpy, but that doesn't seem to be possible. How am I able to use higher resolutions within linux/zoneminder? I noticed even when I access this camera under VLC or cheese, I'm only able to see the same resolutions. Is this a linux limitation?

Here's an output of: sudo zmu -d /dev/video0 -q -v

One other thing I've noticed is that when I set the image to 'Inverted' (I have the camera hanging upside down out of a window), I have random occurrances of the image flipping which I believe is causing a motion detection event. In my logs I receive a bunch of 'Bogus marker length's which I think might be related..

Nobody's run into an issue with their resolutions before?

Please read the forum rules:
viewtopic.php?f=34&t=23833

Do don't bump threads for the sake of bumping. Violations will result in the thread being locked for further comment.

A lack of response means one of two things:
a) you have not provided enough detail
b) no one knows the answer to your question

In your case, b) seems more likely. In which case, you might want to look at another forum to post your question, since the issue you have described is not an ZoneMinder issue, but a Logitech compatibility issue with Linux.

Install uvcdynctrl and read the manual for command line control.

Install guvcviewer and change things with a gui.
