After a bit more investigation, I think the problem is that these
devices now have a new chipset - the vendor id and product id are
0x14aa:0x022a. I found this post
http://lists.zerezo.com/video4linux/msg10122.html but don't really
understand it all. I think I need the new firmware
(dvb-usb-wt220u-zl0353-01.fw ?) plus a patch to the kernel module (but
where do I get this?).

Stephen.
