[pvrusb2] PVR USB2 usb id change

I purchased a WinTV PVR Usb2  model 941 from Circuit City last week but
to date I've had little success getting it to work under linux.

Couple of things I've noted :

1)  The usb device code is 2040:2400 , not the 2040:2900 listed in the code.

     The code in pvrusb2-mci-20060209 compiled cleanly (good work Mike !) 
     plugging in the pvr did nothing on Ubuntu, Debian or Mandrake systems.

     I found the usb id difference, changed pvrusb2-main.c to reflect 
2040:2900 and
     could now hotplug the pvr.

     Hotplug appears to work...but only if the pvr was previously setup in 
     otherwise I get 'device is hung....need to power cycle" message in 
syslog. But
     a power cycle only gives me the same message again.

2)  A previous init in WinXp, followed by boot to Debian gives me what looks 
like a
     clean initialize of the pvr, a /dev/video0 device and a 
     file structure.

     But a  " cat /dev/video0 > test.mpg "  only gives me an emply test.mpg 
and a
     "Warning ... no decoder present " message in syslog.

I wonder if Hauppauge has gone through a revision change on these units, 
reflected in the
usb id change ?

I'm running a fresh install of Debian 'etch' (although my results are the 
same with Ubuntu Dapper),
with the  pvrusb2-mci-20060209 code release.

I welcome any suggestions to get this pvr working, and wanted to send many 
thanks to
Mike Isely for his work on this driver.
