Subject: sysfs: duplicate filename (usb unusual dev?)
My wife got a silly little keychain digital photo frame for a gift.
I'm trying to make it work, but no such luck:
(This is on vanilla 2.6.25)

So I don't get the reason for duplicate sysfs nodes, and the scsi
device for mass storage never shows up (no /dev/sdb is registered,
etc)
Does this look like something that would be resolved with a new
unusual-devs.h entry? Can I find out from this info what type of
unusual-devs macro I might need to get this device working?
