I attached you the log output which clearly indicates trouble. Maybe
some more info on the device: It has in-built memory + a memory card,
which should come up as separate devices. It boots up and shows that it
is connected to a computer, after a couple of seconds (once detach
failed) it will fallback to charging mode. I think the device could also
used as a serial device to gather GPS input, so maybe that's part of the
problem.

Considering the price of the device I wish they would have spent more
money on usb. On the other hand the GPS sensor is fantastic and the
device overall is really awesome (it seems to mount ok under linux and I
couldn't find anyone who had to do any patching for that, the linux
kernel also no quirks for it, so I hope it's just a minor flaw in the
protocol that makes usb2 fail because it aims to be standard compliant :).
