Windows Media Player NS_E_DEVICE_DISCONNECTED fix for 0XC00D0FA2

What triggers this error

You're syncing music or videos from Windows Media Player (WMP) to a connected portable device — an Android phone, an old Zune, a SanDisk Sansa, or even a Walkman. Mid-transfer, WMP freezes for a second, then throws the error: 0XC00D0FA2 with the message "Device is disconnected". You look down and the device is still plugged in, screen on, cable fine. But WMP lost the connection.

Root cause

What's actually happening here is a communication timeout between WMP and the device's MTP (Media Transfer Protocol) stack. The device goes into a low-power sleep state, or the USB controller resets the port because the device drew too much current briefly. WMP expects a constant heartbeat over MTP — if it doesn't get a response within a few seconds, it assumes the device disconnected. The error code 0XC00D0FA2 comes from the Windows Media SDK layer, not from the device itself.

The real culprit is almost always one of three things:

• USB selective suspend — Windows drops power to the USB port to save energy.
• Faulty or loose cable — especially micro-USB or USB-C cables that pass power but drop data lines intermittently.
• Stale MTP driver — Windows uses a generic MTP driver that doesn't handle retries properly.

The fix

Skip reinstalling WMP — that won't do anything. The fix is at the OS and hardware level. Try these in order.

Step 1: Disable USB selective suspend

Windows 10 and 11 love cutting power to USB ports. This kills the MTP connection. Turn it off:

1. Open Control Panel → Power Options.
2. Click Change plan settings next to your active plan.
3. Click Change advanced power settings.
4. Scroll to USB settings → USB selective suspend setting.
5. Set both On battery and Plugged in to Disabled.
6. Click Apply, then OK.

# You can also do this via command line (run as admin):
powercfg /change usb-settings /selective-suspend disabled

Step 2: Use a different USB port and cable

Don't use a front-panel USB 3.0 port — they're often poorly shielded and drop connections under load. Plug directly into a rear USB 2.0 port on your motherboard. USB 2.0 ports deliver more stable power for MTP transfers. And swap the cable: a short, thick cable (under 3 feet) with good shielding. Cheap cables cause this error constantly.

Step 3: Reinstall MTP driver

The generic MTP driver Windows uses can get corrupted after updates. Force a fresh install:

1. Open Device Manager (Win+X → Device Manager).
2. Expand Portable Devices. You'll see your device listed there (e.g., "Samsung Android Phone" or "SanDisk Sansa").
3. Right-click it and select Uninstall device. Check the box "Delete the driver software for this device" if it appears.
4. Unplug the device, then plug it back in after 10 seconds. Windows will reinstall the MTP driver automatically.
5. If it still doesn't work, go to Universal Serial Bus controllers in Device Manager, right-click each USB Root Hub, and select Uninstall device. Reboot. Windows will reinstall them on startup.

Step 4: Disable power management on USB Root Hubs

Even with selective suspend off, individual USB Root Hubs can power down. Kill that:

1. In Device Manager, expand Universal Serial Bus controllers.
2. Right-click each USB Root Hub (USB 3.0) and USB Root Hub (USB 2.0).
3. Select Properties → Power Management tab.
4. Uncheck "Allow the computer to turn off this device to save power".
5. Repeat for all Root Hubs. Click OK.

Step 5: Use Windows Media Player in Administrator mode

This one's a long shot, but if a permissions issue is blocking MTP handshake, running WMP as admin bypasses it:

1. Close WMP completely.
2. Right-click the WMP shortcut and select Run as administrator.
3. Try syncing again. If it works, set WMP to always run as admin: right-click the shortcut → Properties → Compatibility → check Run this program as an administrator.

What to check if it still fails

If you've done all the above and still see 0XC00D0FA2, the problem is likely the device itself or the USB controller on your motherboard. Test your device on another computer — if it works there, your motherboard's USB controller may be failing. Update your chipset drivers from the motherboard manufacturer's site (Intel/AMD chipset drivers, not Windows Update). If the device fails on all computers, its USB port or internal storage is going bad. Back it up and replace it.

One more thing: some Android phones need "File Transfer" (MTP) mode explicitly selected in the notification shade. If it's set to "Charging only," WMP will never see it. Check that before pulling your hair out.
