The error message at the bottom of the screen says: "failed to generate new wallet: Wrong Device Status : SW=6e00 (EXPECT=9000, MASK=ffff)"

This is with Monero GUI v0.14.0.0 and a Ledger Nano S updated to firmware v 1.5.5 on a Win 7 machine.

I tried the different solutions regarding the USB driver issues as prescribed on this answer in this thread: https://monero.stackexchange.com/a/10182/10014

but it's still not working. When I plug in the Nano, the Device Manager screen updates and two new items are added: a 'Nano S' item under 'Other devices' and a 'USB Composite Device' under 'Universal Serial Bus controllers'.

I updated the driver on each one, right-clicking and searching for the driver under 'C:\Windows\winsxs' but still no dice. After the search, the message says "USB Composite Device - best driver already installed".

HarryTheHorse, the poster, mentions that the new item should show up under Smart card readers as a Microsoft Usbccid Smartcard Reader. I had the 'Smart Card' service turned off - I have a lot of unused services turned off for security reasons - but even with it on, the Device Manager does not show a 'Smart card readers' node and when I plug in the Nano and input the key, the same items show up and no 'Smart card reader' item.

Here are some screenshots:

Comodo AV and it quarantined a bunch of monero components/exes, screenshot below. I'll try to redo the drag/drop and see if I can 'allow' install of these components.

  • Which version of the Ledger Monero app do you have installed?

  • On the Nano S device, it says 'App 1.2.2' and 'Spec 0.9.0' and on my Win 7 machine I have the ledger-live-desktop-1.9.1-win installed. Btw, I noticed that there is no 'monerod' file inside the Monero GUI folder. I just downloaded and unzipped the 'monero-gui-win-x64-v0.14.0.0.zip' file contents to a folder and double-clicked on 'monero-wallet-gui.exe'.

  • Thanks for the information. There should be a monerod.exe in the folder. Do you run active AV software (or do you have Windows Defender activated)?

  • I have Comodo Internet Security Premium and it did throw up some flags when I dragged/dropped the 'monero-gui-win-x64-v0.14.0.0' folder from the WinZip screen into Windows Explorer. I just opened Comodo and in the AV panel it had 5 'Detected Threats' and when I clicked on it, the next screen shows all these monero exes that are quarantined. I can post a screenshot on another comment. Should I un-quarantine them or just redo the drag/drop and somehow 'allow' these to be installed?

  • I disabled/turned off Comodo AV and even set the 'monero-gui-win-x64-v0.14.0.0.zip' file as a 'protected object' in Comodo but when I drag/drop, it still quarantines these monero exes.
