hi,
usb 2-2: Product: TvTUNER
usb 2-2: Manufacturer: SKGZ
ID 04ca:f001 Lite-On Technology Corp.
FE has been (mostly, until the 3rd try) detected until 2.6.27.10:
Dec 31 12:01:33 tom1 kernel: MT2060: successfully identified (IF1 = 1241)
but no more with 2.6.28.
can see no recent changes here:

http://linuxtv.org/hg/v4l-dvb/log/6a189bc8f115/linux/drivers/media/dvb/dvb-usb/dibusb-mc.c
this should be the breaking changeset included in 2.6.28 stable kernel release, others are too old:
