Hi,

I have some trouble with a Nova-T USB-Stick.

It's a "WinTV NOVA-T Stick Value, Model 1277" USB-ID:2040:7070.

I use three of it with an ASRock 939A785GMH/128M Mainboard (AMD A785 / SB710) as an Myth-Server.

Currently everything running fine after following all advices found at:
http://linuxtv.org/wiki/index.php/Hauppauge_WinTV-NOVA-T-Stick (Making it Work).

At the modules
* Disabled dvb-rec-polling
* Enabled LNA
* Additional Disabled usb-suspend.

At Myth-Backend
* Disabled all EIT-scans
* set an tuning delay to 1000ms.

Before I changing mythtv, I had errors like:

Apr 13 15:58:07 vdr1 kernel: [ 1887.816045] dvb-usb: error while stopping stream.
Apr 13 15:58:13 vdr1 kernel: [ 1893.137037] dvb-usb: error while enabling fifo.
Apr 13 15:59:38 vdr1 kernel: [ 1978.672048] dvb-usb: error while stopping stream.
Apr 13 16:00:18 vdr1 kernel: [ 2018.165037] DiB0070 I2C write failed
Apr 13 16:00:23 vdr1 kernel: [ 2023.176044] DiB0070 I2C read failed
Apr 13 16:00:26 vdr1 kernel: [ 2026.468132] DiB0070 I2C write failed

Before I disabled the dvb-rec-polling, I had usb-fullstops:

ehci_hcd 0000:00:13.2: force halt; handhake f804c424 00004000 00000000 -> -110

I tested with ubuntu-kernels 2.6.31, 32 and 33.

I can live with this settings, but I have some bad feeling going in holiday for a longer while, leaving the system
alone. Is there anything I can do, help fixing this issues. Enable debug options, sending logs?

Would it help, to use an other usb-chipset (VIA, etc)?

Greetings from Frankfurt
