What is the console output from guvcview --verbose ?
Setting an unsupported device format would only make guvcview drop back
to the first supported device format.

I don't think that's implemented in linux uvc.

Your best bet is to grab a RAW frame and try to analyse it.
I would say that the 372 pix line needs to be converted to 744, UYVY has
2 bytes per pixel, although you need 4 bytes to render 2 pixels, in this
case it seems you are getting a format with 1 byte per pixel.
