Here is another problem with a Hauppauge Nova-T 500 ("DiBcom 3000MC/P"),
but this is not the classical usb disconnect or i2c failure.
Distro: Fedora 8
Linux DVB: hg pull http://linuxtv.org/hg/v4l-dvb on June 9
DIB firmware: dvb-usb-dib0700-1.10.fw
Here is the problem:
The first tuner stays constantly tuned on the same frequency and is
receiving a TS: OK.
The second tuner usage is cycling over 5 different frequencies:
open + tune + receive TS during a few seconds + close + cycle again.
After a few dozens cycles (not always the same number), a read
operation on the dvr device hangs (never returns).
If you stop the application on the second tuner and restart it,
it works again for a few cycles, then hangs again. No message is
reported with dmesg (specifically, no USB disconnect and no i2c failure).
In the meantime, the application on the first tuner continues
