leadtek dvb-t dongle dual not working if plugged in during boot via hub

[Hamish Moffatt]

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.
