Running on Raspberry Pi Zero, I have the same issue. Using smartredraw means the UI freezes on boot, with the persistent CEC notification. As the setting saves a lot of CPU usage, I want to keep it enabled.

Something has changed in LibreELEC 9.2.3 as it also worked fine for me in 9.2.1. This issue is also in nightly LibreELEC-RPi.arm-9.80-nightly-20200628-d1e3bf7.img.gz.

Great. Just out of interest I had a look to see if I could see anything obvious that fixed it from the Linux kernel's git commit log but couldn't find anything.

This is a bit off topic now but I've noticed setting smartredraw in advancedsettings now "freezes" the screen (and killing the kodi process takes a while when it's like this). I've changed nothing else in my advanced settings.

I flashed LibreELEC-RPi.arm-9.80-nightly-20200628-d1e3bf7.img.gz and it works fine now chewitt. Thank you so much!

For reference:

I hope the newer kernel version makes it to the next stable release of LibreELEC

Hello all and thanks for all the hard work on LibreELEC.

I'm trying to connect a no-name small black and red USB Wi-Fi adapter to a Raspberry Pi Zero. According to lsusb it is

ID 148f:7601 Ralink Technology, Corp. MT7601U Wireless Adapter

I'm running LibreELEC 9.2.1.

uname -a


Linux LibreELEC 4.19.106 #1 Tue Mar 3 15:41:09 EST 2020 armv6l GNU/Linux

Relevant (I hope) output of dmesg; I've removed duplicate lines:

I've got it connected to a USB hub connected directly to the Raspberry Pi Zero. It's not a powered hub, however connecting other USB Wi-Fi adapters (ID 7392:7811 Edimax Technology Co., Ltd EW-7811Un 802.11n Wireless Adapter [Realtek RTL8188CUS]) works without problem. I tried connecting it with just a cable (no hub), and it doesn't work either (but the other adapter does).

It works on a Raspberry Pi 2 running Raspbian without problem, which is on an older kernel version.

I'm unsure if the problem is in LibreELEC's kernel support, my USB hub (possible although other USB Wi-Fi adapters work fine), or the USB Wi-Fi adapter itself.

Any help appreciated.
