[ivtv-users] Is this possible? Two pvr 150's with two IR blasters active?

The lirc_pvr150 module only supports Hauppauge cards with a Zilog
Z8F08xx microcontroller IR blaster.  I think there are Hauppauge cards
with an IR blaster that don't use this chip.

Inspect both cards to see if they both have the Zilog Z8 chip.

A quick skim of the lirc_pvr150 code reveals that it should support more
than one Z8 based IR blaster device.

lirc_pvr150 found a Z8 responding on I2C addresses 0xe0 and 0xe2 (or
0x70 and 0x71 if you prefer) on the first card.

lirc_pvr150 did not find a Z8 responding on I2C addresses 0xe0 and 0xe2
(or 0x70 and 0x71 if you prefer) for transmit nor receive on the second
card.


I bet you have a card without a Z8 chip.  Some other lirc or ir module
is required to handle that one, if that is the case.
