MIgrating waves exchange account that used ledger

I think I migrated a waves exchange account that used ledger.
But I may have not understood the migration process properly
But when I login into the wx.network I am presented with the option of 100s of ledger devices to choose from and none I have tried have my balances on them?
How do I know which ledger device number is the correct on?

Any ideas what I need to do or try to find my wallet balances
