Hello all,
I just wanted to update this post with some more information. I'm more
convinced now that this issue revolves around the failure for the
cx25840 module to attach to the second PVR150 on the WinTV500. I added
some debug messages to cx25840 and this is what I get when loading that
module.
cx25840: About to call i2c_probe
cx25840: inside detect_client with address = 68
cx25840: Past functionality check
cx25840: Past kmalloc check
cx25840 debug 0-0044: detecting cx25840 client on address 0x88
cx25840 0-0044: ivtv driver
cx25840 0-0044: cx25843-23 found @ 0x88 (ivtv i2c driver #0)
cx25840: Inside initialize with loadfw = 1
cx25840: Attempting to load firmware
cx25840: inside check_fw_load
cx25840 0-0044: loaded v4l-cx25840.fw firmware (14264 bytes)
cx25840 debug 0-0044: decoder set input (0)
cx25840 debug 0-0044: now setting Tuner input
cx25840 debug 0-0044: set audio input (0)
ivtv0: i2c attach to card #0 ok [client=cx25840, addr=44]
cx25840: Returning from attach_adapter with value 0 (ivtv i2c
driver #0)
cx25840: About to call i2c_probe
cx25840: Returning from attach_adapter with value 0 (ivtv i2c
driver #1)
Any ideas why the cx25840 module would fail to attach to the second
card? i2c_probe is not even calling cx25840_detect_client.
