Why did the Monero GUI fail to generate a new wallet with the Ledger?

Question

I just tried to create a wallet but in the window, after choosing the location for the wallet file, I get this message:

failed to generate new wallet: Unable to enumerate device 11415:11415: NULL device

The system is Windows 10 64 bit.

Can anyone help?

Thanks.

It seems a problem related to Windows USB controller, you can try using the Hardware and Devices troubleshooter to fix the problem. It checks for common issues and makes sure that any new device or hardware attached to your computer was installed correctly.

Also, if you are using your Ledger connected to a USB 3.0 port, you can try to use it in USB 2.0 port, or vice-versa.
