These drivers aren't merged. To get it work, I downloaded drivers according to the kernel version from here
But, there's no new drivers for new kernel (ubuntu 11.04) and I can't find any source code to compile it myself.
My USB tuner is Kworld 380UR
Bus 002 Device 005: ID eb1a:e359 eMPIA Technology, Inc.
and the syslog and kern.log says:
May 15 15:43:09 indrek-laptop kernel: [ 7671.008054] usb 2-5: new high speed USB device using ehci_hcd and address 6
