#
# Allowed properties are:
# ID_AUTOSUSPEND=1
# ID_AUTOSUSPEND_DELAY_MS=####
# ID_PERSIST=0
#
# ID_AUTOSUSPEND_DELAY_MS adjusts the delay for autosuspend to something
# different than the kernel default of 2000ms.
#
# ID_PERSIST=0 allows disabling the kernels USB "persist" feature, which allows
# the continued use of devices after a power loss (due to suspend). Disable it
# if the device will loose state without a USB power session and the driver
