Kirk, try running mode2 and see if any bits are getting through.  If
pressing the same button multiple times yields varying results, you may be
running into the same issue I did.  14.04 and later kernels do not play
well with xHCI and older USB IR receivers which use an older protocol.
Patching the kernel USB driver fixed this for me.
