Re: Fwd: [linux-usb-devel] USB IR receivers and evdev

Hi Kevin,

I would love to have more information about the hardware features and
capabilities of the mce devices.

When I added the transmitter support to the lirc_mceusb2 driver I had
almost no information at all to go by. So if you have more documentation
about these devices that you would like to share I would be very much
interested.
