After performing each step, check if the change has fixed your problem before moving on to the next (more complex) solution.
1. Ledger Software
Make sure your Ledger device has:
the most updated Ledger firmware (≥1.4.2), and
the latest NEO application (≥1.3.1).
Check here (https://support.ledgerwallet.com/hc/en-us/articles/360002731113) for instructions from LedgerHQ to update your ledger firmware.
Check here ( https://support.ledgerwallet.com/hc/en-us/articles/115005173289-How-to-update-the-applications-on-your-Ledger-device) for instructions on how to update your NEO application.
You must update your firmware to the latest version before trying to update your NEO app.
2. Ensure that you are “waking up NEO” before clicking the “Connect” button on the exchange. Usually, the NEO application needs to be open before connecting to the exchange.
3. If you are still unable to connect after the previous two steps, please try deleting and reinstalling the NEO application.
4. Reverse the connection order
Close the NEO App on your Ledger
Click "Connect" on the Switcheo Exchange Login Window
Open the NEO App on the Ledger (Wake up NEO)
5. Your Windows device driver might need to be reinstalled after ledger has been updated to firmware 1.4.2 version.
To force a driver to be reinstalled, and recognize Ledger Nano as a new device (on a PC it was already used on), you will need to delete all USB Input Devices (or find which one was created for Ledger Nano device). You can do this by using the search function on your computer and typing “Computer Management.”
From there, open Device Manager > Human Interface Devices. Once you are in Human Interface Devices, uninstall all USB Input Devices. Then reboot, connect your Ledger to your PC, enter your Ledger PIN. Windows will then find the new USB device and install the correct USB drivers. Lastly, open the NEO application (wake up NEO) and then try connecting to the exchange.
