Summary: USB mouse, flash drive, or phone not detected in Windows 11—try different ports, reset controllers, update chipset drivers, and fix power management.

## The Problem
Nothing happens when you plug in a flash drive, phone, or keyboard—or Windows plays the disconnect sound in a loop. One dead port is often physical; **all** ports failing is usually drivers, power management, or a bad front-panel header. Rule out the device first—it may work on another PC.

## Symptoms
* **USB device not recognized** balloon in the corner.
* Device works on another PC but not this one.
* Front ports dead, rear ports fine (or vice versa).
* Only USB 3 ports fail; USB 2 still works.

## The Fix: Step-by-Step

### Step 1: Test Device and Port
1. Plug into a **rear motherboard port** on desktops (not the case front).
2. Avoid hubs—connect directly.
3. Try another cable (phones and external drives).
4. Reboot with only keyboard/mouse on USB—plug the problem device after login.

### Step 2: Check Device Manager
1. Right-click **Start** → **Device Manager**.
2. Expand **Universal Serial Bus controllers**—look for yellow **!** marks.
3. Expand **Disk drives** / **Portable Devices** when the stick is plugged in—does anything appear?

### Step 3: Uninstall USB Controllers (Refresh Stack)
1. **Device Manager** → **Universal Serial Bus controllers**.
2. Right-click each **USB Root Hub** and **USB Host Controller** → **Uninstall device** (do all of them).
3. **Action** → **Scan for hardware changes**—or reboot. Windows reinstalls generic drivers.

### Step 4: Disable USB Selective Suspend
1. **Control Panel** → **Power Options** → **Change plan settings** → **Change advanced power settings**.
2. **USB settings** → **USB selective suspend setting** → **Disabled** (plugged in and on battery).
3. In **Device Manager**, each **USB Root Hub** → **Properties** → **Power Management** → uncheck **Allow the computer to turn off this device to save power**.

### Step 5: Update Chipset and USB Drivers
Download **chipset** (Intel INF, AMD chipset driver) from the laptop/desktop manufacturer— not just generic Windows Update. Include **USB 3.0/3.1** driver package if listed separately.

After major Windows updates, redo this step—old chipset drivers break USB3 ports often.

### Step 6: Run the Hardware Troubleshooter
**Settings** → **System** → **Troubleshoot** → **Other troubleshooters** → **Hardware and Devices** (name varies by build).

### Step 7: Check BIOS / UEFI
Reboot → **F2** / **Del** / **F12** (vendor-specific) → ensure **USB ports** / **Legacy USB support** / **XHCI** are **Enabled**.  
Reset **Optimized Defaults** if USB died right after a BIOS tweak.

### Step 8: Front Panel Headers (DIY Desktops)
If rear ports work but front do not:
* Power off, unplug AC, open case.
* Reseat the **USB HD AUDIO** / **USB3** front panel cable on the motherboard—consult the board manual for pin layout. One pin offset kills the whole header.

### Step 9: Thunderbolt / USB-C Only
Laptops: install **Thunderbolt** software and drivers from the OEM. Some USB-C ports are **charge-only**—use the port marked with SS or a monitor icon.

## When It Is the Port Hardware
One port never works after liquid spill or bent tab—use another port or a powered hub temporarily. Desktop expansion cards add reliable USB if motherboard ports failed.
