On Windows, libusb 1.0.21 has a bug that causes Trezor T devices to be enumerated twice, although only one of the devices can actually be used. The other one gives "LIBUSB_ERROR_NOT_SUPPORTED" errors when trying to use it. See:
trezor/trezor-core#165
trezor/python-trezor#223

libusb 1.0.22 has recently been released and fixes this bug, please update the Windows build to use this version.

Thanks for making the change, however it looks like the 3.1.3 Windows binaries/installer still include libusb 1.0.21.

Thank you. You made me figure out why I could not reproduce the build. See #4276
This will have to wait again, until the next release, sorry.
