[linux-dvb] udev doesn't detect dvb-usb device

Hi,

my setup:
* Hauppauge WinTV Nova-T USB2
* Ubuntu Dapper (kernel 2.6.15, udev: 079-0ubuntu31)

When I plug the device, dmesg reports detecting a new USB device:

"[4819025.726000] usb 5-3: new high speed USB device using ehci_hcd
and address 7"

and udev also raises USB-add events (see dump below).

But it doesn't go further than that: udev never goes further than reporting
"SUBSYSTEM=usb", or "usb_device", so the DVB rules
in /etc/udev/rules.d/20-names.rules aren't matched (i.e. SUBSYSTEM=="dvb")

The kernel config seems to have all the right flags, though.  Have I
missed something obvious?

Max.
