Hi,
can you send me a picture of your device and further info for
inclusion to my

Erm... you can find an accurate image of it on the AverMedia web site:
http://www.avermedia.com/cgi-bin/products_digitvtuner_dvbtusb2.asp?show=2#
It is identical. If you really want a photo I can try and take one
with a webcam (I don't have a decent camera handy).
Your contribution will help to improve open source support!
Because there are many cards and variations by different
vendors, the developers need _your_ help to get it all supported.
1st priority:
- picture of the device, the device backside (high resolution pics if
feasible)
- lsusb
My understanding is that this is already a supported device. Especially
since it appears to work perfectly with almost everything except mythtv.

further information:
- picture from the device inside (open at your own risk)
It's not obvious how to open this tiny device without
ripping the rubber feet off... so I'll skip that for now.
- if feasible "*.INF" files from the Windows Driver CD
Since I don't run windows... I didn't keep the CD handy, however
I can give you lsusb (although verbose hangs my NetGear 802.11b
USB network plug).

The firmware available on the linuxtv.org site seems to work fine
and match my a800:
http://linuxtv.org/downloads/firmware/dvb-usb-avertv-a800-02.fw
I even tried hardwiring the signal to 100% in the driver but I think
mythtv
must be listening for other driver related tuning events.
static int dib3000mc_read_signal_strength(struct dvb_frontend* fe, u16
*strength)
{
struct dib3000_state* state = fe->demodulator_priv;
u16 val = rd(DIB3000MC_REG_SIGNAL_NOISE_LSB);
*strength = (((val >> 6) & 0xff) << 8) + (val & 0x3f);
*strength = 0xffff; // Doug's disgusting frig!
deb_stat("signal: mantisse = %d, exponent = %d\n",(*strength >>
8) & 0xff, *strength & 0xff);
return 0;
}
Let me know if you do need any more info... but I don't think
this is really due to a hardware variant (unless you know that
tzap returns valid signal strength on other a800s).
Cheers,
Doug
