Hello list, I just buy a Hauppauge WinTV-Duet HD DVB USB stick. I added on my laptop and it works great. The problem is on my Nvidia ION board PC, when I add the stick I get this: [ 3852.016040] usb 1-2: new high speed USB device using ehci_hcd and address 2 [ 3852.149612] usb 1-2: New USB device found, idVendor=2040, idProduct=5200 [ 3852.149620] usb 1-2: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [ 3852.149627] usb 1-2: Product: NovaT 500Stick [ 3852.149631] usb 1-2: Manufacturer: Hauppauge [ 3852.149636] usb 1-2: SerialNumber: 4034588817 [ 3852.149876] usb 1-2: configuration #1 chosen from 1 choice [ 3852.343074] dib0700: loaded with support for 14 different device-types [ 3852.343247] dvb-usb: found a 'Hauppauge Nova-TD Stick (52009)' in cold state, will try to load a firmware [ 3852.343259] usb 1-2: firmware: requesting dvb-usb-dib0700-1.20.fw [ 3852.389203] dvb-usb: downloading firmware from file 'dvb-usb-dib0700-1.20.fw' [ 3852.590849] dib0700: firmware started successfully.
