Hi,
I've found that the Leadtek dvb-t dongle dual (USB 0413:6a05) is not
initialised properly for me if it's plugged in at boot time through a
USB 2.0 hub. Plugging it in later is fine, and plugging it directly into
the PC is fine.

Easy to work around, but perhaps there's a bug. Or it's a timing issue.
