As others have said in the thread, try removing the framerate=
property. image/jpeg is correct here since USB 2 does not have enough
bandwidth for raw video, so video/x-raw will have very low framerate.

With the 1.17.1 development release (and the soon-to-be-released
1.18), you can also use mfvideosrc which is part of the new
mediafoundation plugin.

In general you can see available devices and what elements to use with:

gst-device-monitor-1.0 Video/Source

In apps you should use the GstDeviceMonitor API.
