Reproduce loading a sample app on a Ledger Blue with MCU 3.4-hw15 and SE 2.1.1 using target IDs 0x31000002 and 0x31000004. Trace the target ID handling and device-loading path to determine the supported target ID and document how users should find it; done means the sample app loads successfully or the limitation is clearly reported.

Description

I'm trying to load one of the sample apps to a brand new Ledger Blue (Firmware: MCU 3.4-hw15, SE: 2.1.1). I've tried using both --targetId 0x31000002 and --targetId 0x31000004 and neither one works.

With 0x31000002, I get "Target ID does not support SCP V2", and with 0x31000004 I get "Invalid status 6484". Is there a different targetId I should be using? If so, where should I have found that information?
