Expected Behavior

Device: Samsung Galaxy Note 5
Device codename: noblette
LineageOS: 20-20260409-UNOFFICIAL-NOBLETTE
Build date: 09-Apr-2026
PC: Lenovo ThinkPad L14 Gen 1
OS: Windows
USB: Micro-USB

Expected behaviour

When the Samsung Galaxy Note 5 is connected to a Windows PC using a Micro-USB data cable:

Windows should detect the phone as an active USB/MTP device.
Android should provide USB connection options such as File Transfer (MTP).
With USB Debugging enabled, ADB should detect the device.
Running:
adb devices

should list the connected device.

USB data connectivity should work normally while the phone is booted into Android.

Current Behavior

After installing LineageOS 20-20260409-UNOFFICIAL-NOBLETTE:

The phone charges when connected through Micro-USB.
Windows does not detect the phone as an active USB/MTP device.
Windows shows Samsung-related entries as phantom devices:
SAMSUNG_Android
Status : Unknown
Problem : CM_PROB_PHANTOM

MTP
Status : Unknown
Problem : CM_PROB_PHANTOM
Get-PnpDevice -PresentOnly does not show the Samsung device.
ADB starts successfully but does not detect the phone:
adb devices

List of devices attached

No device is listed.

Possible Solution

NA

Steps to Reproduce

Boot the Samsung Galaxy Note 5 into LineageOS.
Unlock the phone.
Enable Developer options.
Enable USB debugging.
Connect the phone to a Windows PC using a Micro-USB data cable.
Wait several seconds for Windows to detect the device.
Check Windows Device Manager / PnP devices.
Run:
Get-PnpDevice -PresentOnly | Where-Object {
$_.Class -eq "USBDevice"
}
Run:
& "C:\Samsung\platform-tools\adb.exe" devices
Observe that the phone is not listed by ADB and is not present as an active USB device in Windows.
Troubleshooting already tried
Reconnected the Micro-USB cable.
Tried different USB ports on the Lenovo laptop.
Connected the phone directly to the laptop instead of through the Dell Thunderbolt Dock.
Restarted the phone and reconnected the USB cable.
Confirmed that the phone charges through the Micro-USB connection.
Checked Windows PnP device status.
Checked for Samsung/MTP devices using PowerShell.
Confirmed that the Samsung/MTP entries are reported as CM_PROB_PHANTOM.
Confirmed that the Samsung device does not appear under currently present USB devices.
Started ADB successfully using Android Platform Tools.
Ran adb devices; no device was detected.
Confirmed that the issue is not simply an ADB executable/path problem because the ADB daemon starts successfully.

Request to LineageOS team

Please advise whether this is a known USB/MTP/ADB issue with the LineageOS 20-20260409-UNOFFICIAL-NOBLETTE build.

Please also advise which logcat, dmesg, kernel logs, or other diagnostic information should be collected to determine why the USB data/MTP/ADB interface is not being presented by the device.

I can provide the exact Samsung model number, kernel version, recovery version, logs, and additional diagnostic information as required.
