Hello Peter,

Of the devices that you have, which are the ones that are failing?
Both of the dibcom devices?

I am not familiar with how lirc interacts with the dib0700 driver,
since the driver polls the bulk endpoint every 50ms and injects the
keys directly.  I will have to look at the driver and see how this
hooks into lirc.

I suspect that most people are not using lirc at all, since the device
works without it.  This would explain why you are the only person I
know of still reporting these problems.

Could you please send my your lirc configuration so I can attempt to
reproduce the issue locally?  If I can get an environment that
reproduces the issue, I can almost certainly fix it.
