My first act was to plug it into my laptop, with the aim of finding out the USB ID and thus which driver I'd need to compile up (I have a tendancy to build my own kernels with only drivers I think I'm likely to need). I did so and was greeted with:
dvb-usb: found a 'WideView WT-220U PenType Receiver (Typhoon/Freecom)' in cold state, will try to load a firmware dvb-usb: did not find the firmware file. (dvb-usb-wt220u-02.fw) Please see linux/Documentation/dvb/ for more details on firmware-problems. (-2) usbcore: registered new driver dvb_usb_dtt200u
Interesting, think I. I'm more organised than I thought and have already
compiled up all the various v4l bits I thought I might end up using. So I go
looking for the firmware file, find a copy, dump it in
/usr/lib/hotplug/firmware/. Replug the device. And get:
dvb-usb: found a 'WideView WT-220U PenType Receiver (Typhoon/Freecom)' in cold state, will try to load a firmware dvb-usb: downloading firmware from file 'dvb-usb-wt220u-02.fw' usb 1-4: USB disconnect, address 15 dvb-usb: generic DVB-USB module successfully deinitialized and disconnected. usb 1-4: new high speed USB device using ehci_hcd and address 16 usb 1-4: configuration #1 chosen from 1 choice dvb-usb: found a 'WideView WT-220U PenType Receiver (Typhoon/Freecom)' in warm state. dvb-usb: will use the device's hardware PID filter (table count: 15).

Rockin'. Now I need to tune it. I find
Adam's DVB page which has the initial
tuning file for the Tacolneston transmitter in Norfolk. I type
scan uk-Tacolneston. It fails to find anything. I wonder if I'm using the
wrong transmitter. I decide the supplied antenna is probably to blame and go
to see about sorting out the one in the attic. I try again. I get a
channels.conf containing 91 channels. Wooo. Copy this into
~/.mplayer/ and fire up
mplayer dvb://. And have
Freeview on my laptop. Nice.
Unfortunately this requires me to have the loft aerial plugged into my laptop, which isn't very portable. Paddy tell me this will get better when the analogue transmitters get turned off and the digital power ramped up, so I look forward to that. Until then it should still prove useful to have a portable DVB-T stick - I intend to see if I can pick up BBC HD next time I'm staying in London, and check if Freeview coverage has made it to my parents' yet.
Writing this all down makes it seem quite convoluted, but actually the process was a lot smoother than I expected; plug in stick, copy firmware, replug stick, scan for channels, watch tv. The issue that took most time to sort was the aerial. It's really quite cool to think about how easily you can get yourself an MPEG2 stream of TV to play with.
