Just tack these onto a kernel.org 2.6.31.x and that should be it:


You can also grab slightly newer (though in no way relevant to the HDPVR) lirc bits from my git tree.

Yep, I recall seeing the same lirc behavior -- codes transmitted, but lirc still thought things had failed. Don't recall exactly if the fix was in lirc_zilog or the hdpvr driver, but I do recall that I did fix that. :)

USB-UIRT... Is that an lirc userspace driver that is busted? That's one of the few IR things I've not had the chance to play with...
