Hm, I'm not sure what you mean by "debug mode with logging enabled and 
release". Are you running a release build or a debug build? If it is a 
debug build, you need not do anything special to enable ring-3 logging 
while building it and for debug logging you need a debug build.

Also, I assume when you say "USB proxy kernel driver", you're referring 
to the userland proxy device component (USBProxyDevice-win.cpp) which 
isn't kernel code but an ioctl interface to it.

As for VBOX_LOG for that one you could try: set 
VBOX_LOG="+drv_usbproxy.e.l.f"  and don't set VBOX_LOG_DEST. I don't 
remember where "logger" ends up, but by default I think it should end up 
in a debug log file in VirtualBox executable folder. Make sure there is 
any existing VBoxSVC process hanging about when you rebuild things.

Regards,
Ram.
