It is recognized as a mass storage device. I think that means that there
is no problem with the usb-ids.

Did you run lsusb as root? For a normal user these messages are to be
expected as far as I know.

I cannot get anything relevant searching for "FSU215" (only one site
about basketball results, one site about catheters and one site in
Hungarian or something). You could try to google for the vendor id and
product numbers that are listed by lsusb.
Are there any clues from dmesg when you plug in the hub?
