I do still have the Ledger device I set up with the correct PW's I then lost
Well then it turns out that I misunderstood you ). In that case you just need to figure out what the problem is. Does your computer see the device? Could the problem be in the usb-cable or connector?
Would you know if there is a way to get past PW's used on a ledger device from it?
There is no way to get seed phrase out of the device.
