Topping D10s DAC auto standby?

[lelobster]

Thank you all for bringing information about this, this below worked for me on a raspberry 5 / topping dac.

I'm not sure if it suspends my other devices, an SSD and a FLIRC usb, probably, but so far it's not been an issue.

This is added in /etc/rc.local for a 15 minutes delay before port being suspended.

Code:

echo 900000 | sudo tee /sys/bus/usb/devices/1-2/power/autosuspend_delay_ms
echo auto | sudo tee /sys/bus/usb/devices/1-2/power/control
