Oookay. KV, FW 5.8.1
I used the last version of KindleLazy uploaded (third one), put the folder in the extensions folder. Restarted with receiver installed and transmitter active. Started KindleLazy with KUAL. No response.
Deleted the folder and added the first one just to be sure an erorr hadn't been introduced, went through the restart routine again with the same result.
KUAL log says:
ERROR READING evdev2 device
:No such file or directory
Put the receiver on an Android tablet and it is getting a signal, turns the light up and down and the page buttons seem active.
Suggestions? Bear in mind that I'm a little old lady and not a coder.

I hope I just did something stupid, but haven't figure out what.
Installed the Voice update. (Voyage doesn't have it built in, assume it's necessary.)
Still doesn't work..... Same error. Also, no voice settings available. What next?
