The ledger USB doesn’t reset. It’s the ledger live that resets.
So what I do is I add the accounts that I have from my ledger USB to the ledger live. For some reason about 2 months later everything is deleted and I had to start over adding the accounts onto ledger live.
The only reasons that I can think of that Ledger Live account data went missing from within the app are because:
1. The Ledger USB was wiped and setup with a new seed (and therefore new accounts/addresses)
2. The Ledger Live "wallet data" was not found or corrupted (ie. a new/different user account was being used, or the folder with Ledger Live database had been removed, or the Ledger Live database had become corrupted etc)
I opened my Ledger Live app for the first time in months today... and all my data was still there... even after I ran the update to 1.2.7... so I'm not sure what happened on your PC.
