When a Ledger device will not connect, first decide which connection layer is involved. USB, Bluetooth, Ledger Wallet page state, device screen state, and version prompts each point to a different check. Keeping the layers separate avoids repeating the same step without new information.
Use the USB path for cable and port checks
If the device is connected by cable, start with cable fit, port choice, unlock state, and whether Ledger Wallet can open the device. The USB connection checklist gives the most direct path for this layer.
Use the Bluetooth path for mobile pairing
If the issue is mobile pairing, check phone permissions, device distance, and whether the device is ready to pair. The mobile sequence in the Bluetooth pairing guide and the phone connection guide keeps the review focused on the mobile layer.
Read the Ledger Wallet app state separately
Sometimes the cable or Bluetooth path is fine, but Ledger Wallet cannot open the device page. In that case, use the app page checklist before changing connection methods.
Check version prompts after recognition improves
When the device is recognized again, look for version prompts or app notices. The firmware version guide helps confirm whether a visible prompt is part of the next review or only a note to handle later.
