You *MUST* have an adjusted kernel to make certain USB
devices work on<br>
Liva. There was an earlier post about this with this
link on it: It<br>
is a pain, it may be a kernel bug the notes I originally
found this<br>
info from was from someone elses kernel patch.<br>

Jerry used the directions I worked out on mine and that
also fixed<br>
his. There is something funny in the kernel in regards
to it appears<br>
some usb (possibly usb1 low speed) devices on the usb3.
On the liva<br>
both ports appear to be controlled by the same usb3
chipset so both<br>
ports have the issue.<br>
<br>
Without the patch I was getting completely different
garbage each time<br>
pushing the same key.<br>

This is my second Liva. On my first Liva, I am using an
*ancient* Microsoft branded USB IR receiver. It totally
works with LIRC and the stock Fedora kernel. No questions
asked. I've got the unit serving us in the bedroom now and
it works great.<br>
<br>
My original question was, what commercially available IR
receiver are you using with Myth now? I guess I should
have asked what is available that works with standard
Linux distros and LIRC? Because right now this Chinese
unit clearly isn't. Alec has given me a work-around that
sounds like it *should* work. But so far that isn't
helping.<br>
<br>
My other generic MCE receiver that works under CentOS 6
and it's older kernel seems to have stopped working under
the 4.1.5 kernel of Fedora 21 too.<br>
<br>
I bought an HP IR receiver on Amazon hoping it would work.
When it failed like this one I threw it in the trash. I
probably should have held on to it so I could try these
work arounds. but man, that felt *good.*<br>

<div>The problem I ran into - and I'm not saying you are
having the same problem, I don't know - but what I
encountered was a result of a combination of the kernel
usb driver, the Liva USB hardware, and the particular mce
ir receiver I was using. That is, I could use the exact
same kernel and ir receiver on a different computer and
not have the issue. </div>
<div><br>
</div>
<div>On the Liva both USB ports go through xHCI. The ir
receiver I have uses an older h/w protocol which the
kernel driver does not process properly when going through
xHCI. On a different computer, going through a USB 2.0
port, this issue does not happen. The Liva's 2.0 port
however uses xHCI.</div>

It was suggested to try both the 2.0 and 3.0 (I read you are
supposed to call them 3.1 ports now -- whatever) but that didn't
help. So what are you using on your Liva and is there a fix for the
xHCI issue? Roger suggests kernel patching. But as I said my old
Microsoft receiver is working. And if that's not an "old" hardware
protocol nothing is.<br>
