Unable to install swift package due to conflicting requirements.

[ChielChiel]

When I try to install this swift package I get the following response:

$ swift build
Updating https://github.com/Arti3DPlayer/USBDeviceSwift.git
error: dependency graph is unresolvable; found these conflicting requirements:

Dependencies: 
    https://github.com/Arti3DPlayer/USBDeviceSwift.git @ 1.0.3..<2.0.0

My package file looks like this:

// swift-tools-version:4.2
// The swift-tools-version declares the minimum version of Swift required to build this package.

import PackageDescription

let package = Package(
    name: "WiredMouse",
    dependencies: [
        .package(url: "https://github.com/Arti3DPlayer/USBDeviceSwift.git", .upToNextMajor(from: "1.0.3")),
    ]
)```

when I, instead of "1.0.3", set the version to "2.0.0" I get the same result but one step higher: 
```shell
$ swift build
Updating https://github.com/Arti3DPlayer/USBDeviceSwift.git
error: dependency graph is unresolvable; found these conflicting requirements:

Dependencies: 
    https://github.com/Arti3DPlayer/USBDeviceSwift.git @ 2.0.0..<3.0.0

And so on

Can somebody please help me get forward? I'm new to swift package manager so I don't know a lot about it.

Thanks
