[linux-dvb] Tuning doesn't work with Wideview driver

Hi

I recently purchased a Redbell TDT-2Go DVB-T USB stick, as it appeared as 
Linux-compatible at linuxtv.org Wiki (Wideview driver, USB ID 14aa:0226). 
I've compiled and installed the latest CVS version of the dvb v4l drivers, 
and placed the right firmware into the right directory, and it gets loaded 
successfully.

The problem is that, despite the stick is correctly recognized, tuning with 
the scan utility fails miserably. The output is as follows:

I've tried with different kernel versions (Ubuntu Dapper 2.6.15, Ubuntu Edgy 
2.6.17), with the same results. I even downloaded a live-CD version of Ubuntu 
Edgy in order to isolate from other possible problems, with no success.

Looking at system logs, the only strange things are some kind of -110 error, 
and a udevd_event error, but the rest seems ok. Here's the dmesg output when 
the stick is inserted:

Well, I don't know what to try next, I would thank any advice. The situation 
is specially frustrating since I purchased this model because it was 
explicitly stated as Linux-compatible, so I would thank any advice.

Thanks in advance
