[MacOS] Trezor not recognized when plugged in to USB

[ronaldmannak]

System information

Geth version: geth-darwin-amd64-1.7.1-05101641
OS & Version: OSX

Expected behaviour

When Trezor hardware wallet is plugged in the USB, Geth will print WARN [08-10|11:55:19] New wallet appeared, failed to open url=trezor://0003:0007:00 err="trezor: pin needed", as described in PR #14885.

> personal.listWallets should list the available Trezor wallets, like:

INFO [08-10|12:07:35] USB wallet discovered new account   url=trezor://0003:0007:00 address=0x7Bf042272737121236dcBC078A218646C94730f4 path=m/44'/60'/0'/0/0 balance=88999999999876 nonce=4
INFO [08-10|12:07:35] USB wallet discovered new account   url=trezor://0003:0007:00 address=0x89B613B665E9EA122EB1D54f3B54195160cAB8fb path=m/44'/60'/0'/0/1 balance=124            nonce=0
INFO [08-10|12:07:35] USB wallet discovered new account   url=trezor://0003:0007:00 address=0x6742064c46Ccc179C877Ea8782b5d5Fe5b033378 path=m/44'/60'/0'/0/2 balance=0              nonce=0
...

Actual behaviour

• The warning New Wallet Appeared message is not shown when a Trezor is plugged in the USB port
• > personal.listWallets only lists wallets available on disk, not the Trezor wallet.

Steps to reproduce the behaviour

• Start geth with geth. Geth will start in Homestead with ChainID 1
• Start console geth console in a different terminal window
• Attach Trezor.
• Run > personal.listWallets commands

I wrote a quick MacOS to check the USB connectivity. My app receives the USB notifications when a Trezor is attached to the Mac, which suggests the Trezor and not MacOS are not the issue.

USBDevice(id: xxxx, vendorId: 21324, productId: 1, name: "TREZOR", deviceInterfacePtrPtr: Optional(0x0000618000101b20), plugInInterfacePtrPtr: Optional(0x0000618000101b10))
{
    device = "USBDeviceSwift.USBDevice(id: xxxx, vendorId: 21324, productId: 1, name: \"TREZOR\", deviceInterfacePtrPtr: Optional(0x0000618000101b20), plugInInterfacePtrPtr: Optional(0x0000618000101b10))";
}
