1. MCHOSE HUB and Software Issues

MCHOSE HUB is used to configure supported A5 V3 features, including button assignments, DPI stages, polling rate, performance settings, profiles, and firmware updates.

Available features may vary depending on the A5 V3 model, connection mode, firmware version, and MCHOSE HUB version.

MCHOSE HUB Cannot Detect the Mouse

If the mouse works normally but MCHOSE HUB cannot detect it:

  1. Connect the mouse directly to the computer in USB Wired Mode.
  2. Confirm that the cable supports both charging and data transmission.
  3. Try another computer USB port.
  4. Close and reopen MCHOSE HUB.
  5. Disconnect and reconnect the mouse.
  6. Restart the computer if the issue continues.
  7. Install the latest official version of MCHOSE HUB.

Important: BT Mode supports basic mouse operation but does not support all advanced MCHOSE HUB features.

The Mouse Charges but MCHOSE HUB Cannot Detect It

Some USB-C cables support charging only and cannot transfer data. If the mouse charges but is not detected by the computer or MCHOSE HUB:

  • Use the original USB cable when possible.
  • Try another USB cable that supports data transmission.

  • Try another compatible data cable.
  • Try another computer USB port.
  • Connect the mouse directly to the computer instead of using a USB hub.
  • Test the mouse on another computer.

If the problem occurs with multiple cables, USB ports, and computers, the mouse cable connector or USB-C port may require inspection.

4. 2.4GHz Receiver Pairing Issues

The Mouse Cannot Connect to the 2.4GHz Receiver

Before attempting to pair the receiver again:

  1. Confirm that the receiver is connected to the computer.
  2. Switch the mouse to 2.4GHz Wireless Mode.
  3. Make sure the mouse has sufficient battery power.
  4. Reconnect the receiver to another USB port.
  5. Turn the mouse off and back on.

The Receiver Needs to Be Paired Again

If the mouse and receiver no longer recognize each other, use the official A5 V3 receiver-pairing procedure for your specific model.

Important: Do not use pairing instructions or receivers intended for another MCHOSE mouse model. Pairing methods may vary between A5 V3 versions.

If pairing continues to fail, prepare the product model, receiver information, and a video showing the issue before contacting MCHOSE Customer Support.

5. Sensor and Tracking Issues

The Buttons Work but the Cursor Does Not Move

  1. Check whether dust or debris is blocking the sensor opening.
  2. Gently clean the sensor area with a soft, dry cloth or cotton swab.
  3. Test the mouse on a compatible mouse pad.
  4. Avoid transparent glass, mirrors, and highly reflective surfaces.
  5. Reconnect the mouse and test another connection mode.
  6. Test the mouse on another computer.

Important: Do not apply liquid directly to the sensor or scratch the sensor lens.

The Cursor Jumps, Shakes, or Moves Unexpectedly

  • Clean the sensor area.
  • Test another clean mouse pad or surface.
  • Check whether the mouse feet are damaged, worn, or uneven.
  • Restore recently changed sensor settings to their default values.
  • Reduce the polling rate temporarily and test again.
  • Test the mouse in USB Wired Mode.

Tracking Stops When the Mouse Is Lifted and Repositioned

Lift-off Distance (LOD) controls the height at which the sensor stops tracking when the mouse is lifted.

  • Open MCHOSE HUB and check the current LOD setting.
  • Test another available LOD setting.
  • Use a clean cloth or hard mouse pad designed for optical sensors.
  • Restore the performance settings to their defaults if the issue began after customization.

Available LOD settings may vary depending on the A5 V3 model and firmware version.

Tracking Feels Different After Changing Settings

The following settings may change how cursor movement feels:

  • DPI
  • Polling rate
  • Motion Sync
  • Lift-off Distance (LOD)
  • Angle Snapping

Restore one setting at a time and test the mouse after each change. This can help identify which setting is affecting tracking behavior.

6. Mouse Button Issues

A Mouse Button Does Not Respond

  1. Reconnect the mouse.
  2. Check the button assignment in MCHOSE HUB.
  3. Restore the button to its default function.
  4. Confirm that the correct profile is active.
  5. Test the button in another application.
  6. Test the mouse on another computer.

If the button works after its default assignment is restored, the issue was likely caused by the previous software configuration.

The Side Buttons Do Not Work

  • Confirm that the side buttons have not been disabled or reassigned.
  • Check the active profile in MCHOSE HUB.
  • Apply and save the button assignments again.
  • Restore the default button configuration and retest.

Note: Some games or applications may not recognize every assigned command. Test the button with a standard keyboard shortcut or mouse function to determine whether the issue is application-specific.

A Button Registers Multiple Clicks

If a single press sometimes registers as multiple clicks:

  • Test the button in more than one application.
  • Restore the default button settings.
  • Check for an available firmware update.
  • Test the mouse on another computer.

If the problem remains after testing the default settings on another computer, contact MCHOSE Customer Support for hardware assistance.

The Scroll Wheel Does Not Scroll Correctly

  • Check for visible dust or debris around the scroll wheel.
  • Turn off the mouse and gently rotate the wheel several times.
  • Reconnect the mouse.
  • Test scrolling in another application.
  • Test the mouse on another computer.

Important: Do not pour or spray liquid into the scroll wheel area. Moisture may damage internal components.

The Middle Button Does Not Work

  1. Check the middle-button assignment in MCHOSE HUB.
  2. Restore the middle button to its default function.
  3. Test it in another application.
  4. Test the mouse on another computer.

The Scroll Wheel Feels Loose or Difficult to Turn

Check whether debris is trapped around the wheel. Do not apply excessive force or attempt to open the mouse.

If the wheel remains loose, difficult to rotate, or produces unusual noise during normal use, contact MCHOSE Customer Support.

8. Factory Reset

If incorrect settings cause unexpected button, DPI, or performance behavior, restoring the mouse to its factory settings may help.
