WebUSB .claimInterface never returns on Windows - webusb

Question

I have been working on an website that uses WebUSB. The WebUSB library works 100% on Linux and Android. Unfortunately on Windows the promise returned by .claimInterface never returns anything, ever. And when I, for interest sake, run the claimInterface again the returned promise returns the error "An operation that changes state is in progress", confirming that the first claimInterface function is still busy.
The problem only occurs when claiming interface 1, claiming interface 0 works, but this interface is of no use to me. The USB device is not standard (descriptor dieplayed below) so it might be something about the device configuration, but it is really hard to tell with the lack of logs.
I did try and look at chrome://device-log?refresh=1 for additional logs, but only the plug events are dislpayed. I also enabled the new USB backend at chrome://flags/#new-usb-backend to no avail. I also tried running chrome with the --enable-loging --v1, but the only error that seemed relevant is: ERROR:device_event_log_impl.cc(211)] [01:32:33.170] USB: usb_device_handle_win.cc:1020 Failed to read descriptor from node connection: A device attached to the system is not functioning. (0x1F) .
But this error is logged before I have even connected a device, also discussed here, so I do not even know if it is relevant.

As well as a React App I used to test the library.
import { useEffect, useState } from 'react';
export default function App() {
const [devices, setDevices] = useState([]);
useEffect(function () {
update()
navigator.usb.addEventListener("connect", update);
navigator.usb.addEventListener("disconnect", update);
}, [])
return (
<div className="App">
<button onClick={refresh}>
<div>Refresh</div>
</button>
<button onClick={connect}>
<div>Connect</div>
</button>
</div>
);
function connect() {
let _device = devices[0]
if (_device) {
_device
.open()
.then(function () {
_device
.selectConfiguration(1)
.then(function () {
console.log("Connecting to interface")
_device
.claimInterface(1)
.then(function () {
console.log("Success");
})
.catch(console.error);
})
.catch(console.error);
})
.catch(console.error);
}
}
function update() {
navigator.usb.getDevices().then(function (_devices) {
setDevices(_devices)
});
}
function refresh() {
navigator.usb
?.requestDevice({
filters: [{ vendorId: 0xXXXX, productId: 0xXXXX }],
})
.then(update)
.catch(console.error);
}
}

I downloaded goole-chrome canary 89.0.4387.0 and it solved the problem. So I guess that is just google, solving the problem before I even asked the question.
