Umm, "looks better" isn't a reason we can have a discussion about.
Why would you want to export any result from sysfs if a libusb program
can collect the data directly? Given that "real" applications for "real"
devices will want to move data from and to userspace eventually, a
loopback test that doesn't even touch userspace seems to me to be kindof
unrealistic and therefore of questionable utility.
