1 EnhancedPowerManagement causing the issue on any map
2 Somekind of Altis loading issue killing the device detection of ArmA III

@cpt_keys - Your issue is not related to the issue that input devices disapear when running a Altis map, but when running Straitis all works flawless, please read the input of other users.

still have the issues it did accure about 12 weeks ago after a minor Arma 3 or Steam update:

Devices which stop working:
Device Name: Saitek Pro Flight X-55 Rhino Stick
Vendor ID: 0x0738
Product ID: 0x2215

Device Name: Saitek Pro Flight X-55 Rhino Throttle
Vendor ID: 0x0738
Product ID: 0xA215

MFG Crosswind Rudder Pedals
Vendor ID: 0x8564
Product ID: 0x0203

I also do use TrackIR but it still works flawless.
The finny thin it does still work in the system and in the programming software for the devices.
Also when I bind keyboard keys to the buttons they are recognized by ArmA 3.

This is very frustration as I am totally used to fly with my hotas and the pedals and currently can not support my squad in the air.

Hope somebody finds a solution soon, I'm starting to loos my fun in ArmA.

Solutions tried and failed:

• delete device drivers and devices and reinstlall them.
• Delete Arma 3 and resintall it.
• totally clean system installation.
• Tried devices on USB 3 and 2
• run ArmA 3 in win 7 compatibility
• Turned off power management in registry windows 8.1
• Tried to run devices on a external powered USB 3.0 hub and usb 2.0 Hub

This issue only occurs only when entering a Altis map on Stritis all works flaw less.
