Problems getting PCTV 292E working

Hi,

Thought I'd post here as I know a number of you have played with DVB 
devices.

I'm currently in Scotland.  I bought a PCTV Tripplestick 292E 
(http://www.linuxtv.org/wiki/index.php/PCTV_Systems_tripleStick_T2_(292e)) 
to watch local free-to-air TV (aka Freeview).

I'm running Debian Jessie on a Linux VM running under VMWare Fusion 7 (yes 
I know 8 is out now) on a late-2011 Macbook Pro.  I'm using the stock 
Jessie kernel.

Linux portkey 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt11-1+deb8u3 
(2015-08-04) x86_64 GNU/Linux

I plugged the 292E in and told VMWare to connect it to the Linux VM. 
Linux recognised the device right away and set up the DVB devices.

I downloaded the 292E firmware files from 
http://palosaari.fi/linux/v4l-dvb/firmware/Si2168/ and copied them to 
/lib/firmware/

$ ls -lh /lib/firmware/
total 60K

I invoke w_scan as follows:

# w_scan -f t -c GB -F -t 3

w_scan fails to find any channels and errors get printed to syslog.

I did some earches for the i2c errors but found mostly code references and 
little that's relevant.

I do note that it doesn't appear to have loaded firmware from either the 
a20, a30 or b40 firmware files.  Not sure how to make this happen.

I will keep digging but I thought maybe someone here might have some 
whisdom.

Thanks,
Geoff.
