Bug Description

Binary package hint: lirc

"The lirc_mceusb2 driver as is has a rather annoying data queuing
 bug that results in key stutter. A key that is being continuously
 pressed will result in the driver sending a burst of 3 or so keys
 followed by a quiet period while a set of another 3 keys is being
 queued." - Maciek Klimkowski

Maciek included a patch, which can be found here:
http://www.phobos.ca/dvb/lirc-0.8.0.pre4-mceusb2_key_stutter_fix.patch

This patch made a world of difference for me. My remote went from being just barely functional to being wonderfully responsive.

Just a small clarification, even though the patch name suggests it's for 0.8.0.pre4, it applies equally well to the vanila 0.8.0 that can be downloaded from the LIRC homepage right now.

Furthermore this thread looks important. Basically 0.8.0 and 0.8.1 is already broken under kernel 2.6.20. The version in cvs is required now.

So until the new release of lirc is made, lirc_mceusb2 will be broken for fiesty.
