[FEATURE REQUEST] Trezor Safe 7 compatibility

[emailschaden]

Looks like Trezors new device, the Safe 7 is now only supporting the Trezor Host Protocol v2 (link) which is used to relay protobuf messages with different channel IDs every time it connects, contrary to the old magic number system.

The Safe 7 uses the same USB VID/PID as the Model T (0x1209:0x53C1), so detection of the device is already done, it's just not properly communicating with the device.

I assume theres two ways to implement this device, either through implementing THPv2 or as issue #8263 suggests, implementing SLIP-0010 to potentially standardarise the compatibility with future Trezor, Ledger and potentially other hardware wallets.

Without knowing much about the difference but if you put it that was "implementing SLIP-0010 to potentially standardarise the compatibility with future Trezor, Ledger and potentially other hardware wallets" sounds much nicer :)
Can't wait for this. My ledger stax keeps resenting when i use monero wallet. Would love to to be able to use my new Trezor for monero.

I have previously added more details here in this thread

monero-project/monero-gui#4517 (comment)

There is a whole new protocol communication that's e2e encrypted. It will need to either be ported to c++, or use trezor's python/node.js libraries, or wait for Trezor's rust library.

I think waiting for rust implementation would be better for the project, bringing a lot of functionality is also a lot of burden for monero to maintain our own implementation of the protocol.
