Hello Matthew, please try this code to see if it helps.

No change. The difference between your code and mine is it calls pmInit and provider->joinPMtree, but the IONetworkController had already done that.

As it turns out the scenario is more complicated that I had thought under 10.2.3:

1) Insert card, wait for it to initialize
2) Put machine to sleep
3) Remove card
4) Wake machine up.
5) Insert card while machine is in the midst of waking up
6) The driver's "start" routine is called, and at some point the driver's "registerWithPolicyMaker" routine is called
7) registerWithPolicyMaker calls policyMaker->registerPowerDriver(this, myPowerStates, myPowerStateCount)
8) Before that call returns, the driver's setPowerState is called with a power state of 0 (device off)
9) setPowerState is not called again.

Under 10.2.4, steps 3 and 5 are not necessary, reportedly.
