[mythtv-users] I2C RW failure, with experimental 80e driver...

[Martin, Charles]

Hi all -

  This time, I'm trying to bring up an 80e PCTV device, using the Micronas drx3933 driver obtained from here:

http://www.kernellabs.com/hg/~dheitmueller/v4l-dvb-80e/file/30c6512030ac

   It was pretty easy to set up, and the device seems to register fine on my target system when I plug in the 80e.

However, when I try to tune in, I get this error:

drx3933: I2C write/read failed
drx39xxj: could not get lock status!
drx3933: I2C write/read failed
drx39xxj: could not open i2c gate [-2]

Is it possible I'm missing some option when configuring my kernel for I2C?  I'm just wondering if anyone else encountered this problem (Mr. Heitmueller?)

Thanks, Charles.
