[linux-dvb] Pinnacle HD Stick (801e SE) and i2c issues

[John Orth]

First, thanks to all for the wonderful v4l project.  I am able to get 
this card going in Ubuntu 9.04 on my laptop (Dell Vostro 1700) with no 
changes apart from copying the correct firmware.  What fantastic 
progress. :)

I have been trying very hard to get this USB tuner to work on my Asus 
M3A78-EM board in Ubuntu 9.04 with no success.  I have tried the stock 
Jaunty kernel, the mainline (vanilla?) kernel, the included kernel 
modules, and modules compiled from v4l Mercurial with no success.  
Generally speaking, after a cold boot, the stick will work for a while.  
It will scan channels, lock one or two, and then I will receive a filter 
timeout.  Once the filter has timed out, not even a cold boot will 
revive the stick.  I have to power down the system, remove the stick, 
and place it in a different USB port.  Once I have done this, I am able 
to filter/lock with varying degrees of success.  Sometimes it will allow 
me to generate a full channels.conf, sometimes not.  However, once 
hitting the "filter timeout" error, dmesg gets flooded with:

---
s5h1411_writereg: writereg error 0x19 0xf5 0x0000, ret == 0)
dib0700: i2c write error (status = -108)
---

The filter timeout occurs after running "scan tuning.dat > channels.conf"
The file tuning.dat is generated via "w_scan -fa -x > tuning.dat"

The firmware dvb-fe-xc5000-1.1.fw was copied to /lib/firmware per the 
v4l Wiki instructions.

Is there something major I'm overlooking?  Are there any known issues 
with this hardware combination?  I am willing to test any changes to the 
xc5000 driver if needed.

Thanks!
