Hi folks,
I've got Igor's debian stretch server image for cubietruck running, compiled sunxi kernel 4.16.0-rc1 without power management options, but can't get USB autosuspend disabled.
There are a few posts regarding this issue, but they don't resolve my issue, since in the stretch system I don't have entries for /power/level or /power/control of the usb devices, it just doesn't exist.
Thus I can't fix this issue setting /power/control to 'on'.
/sys/bus/usb/devices/$device/power DOES NOT EXIST
/sys/bus/usb/devices/$device/power/level DOES NOT EXIST
/sys/bus/usb/devices/$device/power/control DOES NOT EXIST
/sys/bus/usb/devices/$device/power/autosuspend DOES NOT EXIST
Besides general power management options I didn't find any options regarding USB devices in the kernel config.
I disabled USB_DEFAULT_PERSIST, but that didn't change my issue.
Has anyone fixed that problem with this kernel and missing entries listed above ?
Kind regards,
Martin
