Actually I was looking at my own experiments when writing that comment.
It looks like this

So this comment only made sense in that context. Hope this clarifies.

p.s. if you're curious about temp/163 that's because of this commit.

(Yes, we probably should name it 'ignored_device_at_<sysfs_path>')
Btw, on Mac OS X the fake optical drive shows in the UI for the Sandisk
U3 Cruzer Micro. I'm sure they're thrilled about SanDisk's Windows-only
value-add crap too!
