Yes.  The log shows that your camera's USB firmware doesn't work right.  
It fails to respond to a Clear Endpoint halt request.  That's probably why
you needed to create an unusual_devs entry to access it in the first
place; since the camera doesn't support the standard protocol correctly,
the manufacturer decided to make it vendor-specific.

If you wanted to use it with Windows or Mac OS, would you need to install 
a special driver?  If yes, then it probably won't work with Linux at all.
