Ledger Flex seems to not be recognized

[Ethnical]

Bug Description

The ledger flex is not recognized and thus will cause simulation to use overrides and will likely fail.

Steps to Reproduce

1. Connect the ledger flex
2. Sign the task -> https://github.com/ethereum-optimism/superchain-ops/tree/main/tasks/sep/021-refresh-signers-fakeFoS

This will show this message error 'legder not found':

and then simulated with the overrides an fail.

Expected behavior

To detect the ledger and simulate correctly the task.

Worth noting that: Recently, we upgrade eip712sign to v0.0.8 to fix some ARM problem (see there:#375)
But doesn't seems to help there..

This is likely a device id not existing in the ledger Go library used by geth

Just tried signing task sep/021 again with a Flex and eip712sign v0.0.8 and again got error Warning: signer creation failed: no ledgers found, please connect your ledger.

I can normally sign transactions with the Flex and the Ledger Live app.
