Tried different solutions from askubuntu forum post shared by white-round-square:
usbresetfrom usbutils package:
sudo usbreset 1eaf:0003
Resetting Maple 003 ... ok- unbind-rebind:
echo 1-1.1 | sudo tee /sys/bus/usb/drivers/usb/unbind
sleep 1
echo 1-1.1 | sudo tee /sys/bus/usb/drivers/usb/bind - toggle authorized flag:
sudo sh -c "echo 0 > /sys/bus/usb/devices/1-1.1/authorized"
sudo sh -c "echo 1 > /sys/bus/usb/devices/1-1.1/authorized"
Nothing worked. It just resets the keyboard in bootloader or some other state:
Bus 001 Device 005: ID 1eaf:0003 Leaflabs Maple DFU interface
Could we install a capacitor (or similar hardware mod) on the keyboard’s USB power line to smooth out brief voltage dips?
