[mythtv-users] power off and on frontend only with remote

[Mario Limonciello]

Leighton,

This is the same problem you had with 2.6.17.  The light on the mceusb2
receiver will light up, but then won't power the machine on.  I'll
experiment with this later on after work.  Unfortunately, I'm quite
reluctant to move up to a newer kernel just to solve this problem as
everything else in edgy works perfectly.  I'd almost rather backport the
changes to USB (or whatever changed) to this kernel, but that would be just
as much work considering the way edgy does things. :(

Thanks for the info,

Mario
