Yes.

You can't do either one until you enable CONFIG_PM. To test
suspend/resume you also have to enable CONFIG_PM_SYSFS_DEPRECATED.
Then to suspend your USB device, do:
echo -n 2 >/sys/bus/usb/devices/.../power/state
(where ... is the device's name.) To resume, to:
echo -n 0 >/sys/bus/usb/devices/.../power/state
To test remote wakeup, do:
echo enabled >/sys/bus/usb/devices/.../power/wakeup
before suspending.
