Subject: [PATCH] rt2500usb: fix powersaving random failures
Date: Mon, 29 Mar 2010 09:56:53 +0200 [thread overview]
Message-ID: <201003290956.54234.linux@rainbow-software.org> (raw)
This patch seems to fix random powersaving failure where the device state is
stuck at 1 (STATE_SLEEP) and does not change to 3 (STATE_AWAKE), resulting in
to associate and these error messages:
phy0 -> rt2500usb_set_device_state: Error - Device failed to enter state 3 (-16).
No probe response from AP xx:xx:xx:xx:xx:xx after 500ms, disconnecting.
