Yes, I checked that there are no overriding settings.
Also this code from PRSCustomizer indeed shutdowns the reader:
Code:
<boolean key="0x27-hold" do="doDeviceShutdown"/>
But substitution doDeviceShutdown -> doSuspend does nothing
Suspension from volume keys does not work too.
Code:
<boolean key="0x41-hold" do="doSuspend"/>
<boolean key="0x40-hold" do="doSuspend"/>
