TransportOpenUserCancelled error when attempting to connect a ledger nano using CW

[kjozwiak]

Description

Connecting to a Ledger Nano stopped working on Nightly. You'll get a TransportOpenUserCancellederror when viewing the browse console for CW via brave://inspect/#extensions. However, Trezor works without any issues once you've installed the needed bridge so it seems to be ledger nano related.

Steps to Reproduce

1. launch Nightly (used 1.30.41 Chromium: 93.0.4577.51 in this case)
2. ensure that you have a nano ledger connected/unlocked and ETH selected
3. visit brave://wallet and attempt to connect to the ledger nano

I tried connecting it on BETA & Release and it worked without any issues:

• 1.29.67 Chromium: 92.0.4515.159 - Couldn't reproduce
• 1.28.106 Chromium: 92.0.4515.159 - Couldn't reproduce
