Environment

• Where are you running caravan: unchained-capital.github.io
• Operating system: Windows
• Browser and version: Chrome 87

Chrome v87+ enables a "new usb backend" by default:

We are rolling out enabling chrome://flags#new-usb-backend by default in M-87
from this chromium dev link.

This doesn't work well with Ledger. A workaround:

Disable the new-usb-backend and use the old version:

1. Paste this in the Chrome URL bar: chrome://flags#new-usb-backend
2. Change it to be Disabled if it shows up as Default enabled.
3. Chrome will refresh

Confirmed it works, it would be good if caravan had a warning or notice to warn users if the ledger import fails and the user agent is greater then chrome 87
