[pvrusb2] Some install guidance on WinTV PVR2 USB

Hey Mike, 

Pathetic I know, but I finally found my WinTV! I used the polarity you said (Positive in the center) and lsusb shows:
Bus 001 Device 003: ID 045e:0730 Microsoft Corp. Digital Media Keyboard 3000
Bus 001 Device 004: ID 045e:00e1 Microsoft Corp. Wireless Laser Mouse 6000 Reciever
Bus 002 Device 010: ID 2040:2400 Hauppauge WinTV PVR USB2 (Model 24019)
Bus 002 Device 003: ID 0cf3:3005 Atheros Communications, Inc. AR3011 Bluetooth

So it is seen... that should mean it isn't borked right?

I will follow up with the correct polarity (by checking what I do have).

However if you already tried it "both" ways, then odds are likely that 
you already "let the magic smoke out".  Low voltage digital logic 
behaves very destructively if fed reversed power.  Generally if the 
device in question expects "unregulated" power coming in and has its own 
on-board regulator, then there's a *chance* it might survive reversed 
power - because only the regulator will have been exposed to the 
condition.  Or maybe just the regulator got fried which might be fixable 
(especially if its a cheap little 7805 3-terminal linear device).

Given that the brick supplies 6V and the onboard logic there is probably 
wanting 5V, then there very well may be an onboard regulator.

I misplaced the power supply awhile back. I know it is 6 volts DC, but it doesn't indicate the polarity. I am going to assume that the center is + and the outside is -, since that is the way their new stuff is. Is that correct? I suppose I ruined it by trying it both ways, although no smoke, or any indication I smoked it.
