I have seen the same problem.
I have made a little change on the /usr/src/linux/drivers/media/tuners/fc2580.c file, and compiled a new fc2580.ko module, and it works fine.

There is now kernel support for the demodulator and the USB bridge (af9035 chip) and for the tuner (FC2580).

Glue code to support the Asus U3100 Mini plus has now landed in the current staging tree and has been pull-requested for 3.7.

USB Quircks should no longer be needed for this device. For the time being still listed here.

The original rare drivers v9.08.14.1 had been uploaded to http://ubuntuforums.org/showpost.php?p=10176778&postcount=20

Compiling v9.08.14.1 may be very adventurous. I have made some pathology to original driver :) and reduce it only to ASUS_U3100_mini device and fix various incompatibilities. Minimum additional modification are needed to installing. Works well for kernel < 2.6.35.

This old driver currently still lives in my git repository for the AF903x and keep pushing changes I receive until 3.7 is released.

09.07.2013 The device does not seem to work. Seems to be a problem with I2C communication between frontend and tuner. The error is
