given the susceptibility of some OSS implementations, I'd suggest 
reimplementing the test loop as:
for fmt
	for channels
		for rates
			if open succeeds
				1/ flag format as supported
				2/ close device
			endif
		endfor
	endfor
endfor
this would also put us out of danger if the device doesn't accept 
changing its mode on the fly
