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.
