[mythtv-users] MCE/HID remote double events

I'm trying to set up an MCE remote using evdev, and I'm getting double events in Mythfrontend for every key fairly consistently; maybe 80% of the time.

I've set up the remote from a combination of these two wiki articles:


evtest usually doesn't report the extra event even when Mythtv does.

I've even set repeat delay and period to really high values.

For example, here's an instance where pressing "down" resulted in event, but 'evtest' didn't:
Testing ... (interrupt to exit)
Event: time 1560729712.782138, type 4 (EV_MSC), code 4 (MSC_SCAN), value 800f041f
Event: time 1560729712.782138, type 1 (EV_KEY), code 108 (KEY_DOWN), value 1
Event: time 1560729712.782138, -------------- SYN_REPORT ------------
Event: time 1560729712.888133, type 4 (EV_MSC), code 4 (MSC_SCAN), value 800f041f
Event: time 1560729712.888133, -------------- SYN_REPORT ------------
Event: time 1560729713.022172, type 4 (EV_MSC), code 4 (MSC_SCAN), value 800f041f
Event: time 1560729713.022172, -------------- SYN_REPORT ------------
Event: time 1560729713.294223, type 1 (EV_KEY), code 108 (KEY_DOWN), value 0
Event: time 1560729713.294223, -------------- SYN_REPORT ------------

Here's ir-keytable output:

Found /sys/class/rc/rc0/ (/dev/input/event8) with:
	Name: Media Center Ed. eHome Infrared Remote Transceiver (1784:0011)
	Driver: mceusb, table: rc-rc6-mce

	Repeat delay = 10000 ms, repeat period = 10000 ms

FIW the remote is a Logitech harmony 650 programmed as a Windows Media Center PC.

Thanks in advance,
