The device with USB ID 1f4D:9016 (which is for the most current device) is only supported in kernel 2.6.37 or greater.

Mythbuntu 10.10

• Devices with USB IDs 13d3:3226 and 1b80:e402 are supported out of the box.
• When the device is inserted, Mythbuntu offers to install the firmware (installs dvb-usb-af9015.fw to /lib/firmware). Need to reboot.
• Upgrading the kernel to 2.6.37 adds the same support for the latest V3 device (USB ID 1f4D:9016) i.e. offers to install firmware
• IR Receiver (i.e. remote control) not tested.

Ubuntu 11.04

• Had an issue with using a pair of these (device id 1b80:e402). Although Ubuntu installed the drivers out-of-the-box, there were two missing frontends in /dev/dvb - adapter 0,1,2,3 were present, but only adapters 0 and 2 contained frontends unless I removed and re-inserted the tinytwins while Ubuntu was running. The fix was simply to grab the latest firmware (in the table above) and copy it to /lib/firmware, and reboot.
