I'm trying (unsuccessfully) to use lirc with the latest version of the
WinTV-PVR USB2
with the external IR blaster. I ended up enabling full debugging in the driver
and found that the driver is just sending zeroes across the fake I2C bus.
Everything
in the logs looks pretty normal until I enable debugging.
With /dev/lirc symlinked to /dev/lirc0, when I run irw or irrecord, I get an
endless stream of
Apr 28 21:02:16 mythserver kernel: [ 889.568090] pvrusb2 i2c xfer 1/1:
addr=0x18 len=3 read [00 00 c1] result=1
and with it symlinked to /dev/lirc1, I'm seeing
Apr 28 20:59:55 mythserver kernel: [ 747.998956] pvrusb2 i2c xfer 1/1:
addr=0x71 len=6 read [00 00 00 00 00 00] result=1
Looking at the code, it's obvious that /dev/lirc0 was the right one, and by
adding a few
debugging printk calls, I determined it was falling into this path:
/* Mangle the results into something that looks like the real IR
receiver. */
rdata[2] = 0xc1;
if (dat[0] != 1) {
/* No code received. */
rdata[0] = 0;
rdata[1] = 0;
printk("IR no code received.\n");
I don't see any indication in the debug logs that would suggest that anything
isn't working,
it just isn't seeing any data. I've tried both third-party remotes and the
remote that came
with it, and it just can't see anything.
Ironically, the only reason I'm even trying to use the remote is that nobody
has remote
codes for EITHER of my DirecTV boxes (Hughes HRM-5 remote, Panasonic EUR511159
remote).
Any ideas? I've been fighting with this problem since last weekend, and if
it's bad hardware,
I'd like to know now so I can swap it at Fry's for a working one. :-)
