Trying to open a device using HidDevice FromIdAsync in UWP always returns null unless using FileAccessMode.Read

I can confirm that my HID device can have read and write capabilities, because this has been verified in WPF application, where one Endpoint can read and the other can read and write.
I thought it might be a permissions issue, but I defined almost every possible Usage in the manifest, and this still doesn't work.
Is there any other way to test HID besides buying SuperMUTT? (It costs 350$)
My code:
csharp
//This method will be called on the UI thread
private async Task OpenDevice()
{
string aqs = HidDevice.GetDeviceSelector(0x0001, 0x0005, 0xAAAA, 0xBBBB);
//Two Endpoints are returned here, one of which can only be opened by Read, and the other cannot be opened by Read or ReadWrite
var devices = await DeviceInformation.FindAllAsync(aqs);
foreach (var deviceInfo in devices)
{
var access = DeviceAccessInformation.CreateFromId(deviceInfo.Id);
if (access.CurrentStatus == DeviceAccessStatus.Allowed)
{
var deviceWithReadWrite = await HidDevice.FromIdAsync(deviceInfo.Id, FileAccessMode.ReadWrite);
//deviceWithReadWrite is null
var deviceWithRead = await HidDevice.FromIdAsync(deviceInfo.Id, FileAccessMode.ReadWrite);
//deviceWithRead is not null
}
}
}
Capabilities in Package.appxmanifest
<Capabilities>
<DeviceCapability Name="humaninterfacedevice">
<Device Id="any">
<Function Type="usage:0001 *"/>
<Function Type="usage:0009 *"/>
<Function Type="usage:FF00 *"/>
<Function Type="usage:FFF0 *"/>
<Function Type="usage:FF80 *"/>
</Device>
</DeviceCapability>
</Capabilities>

Welcome to Microsoft Q&A!May I ask you also use the same API in your WPF app?
Thank you,

2022-12-07T09:02:44.09+00:00 You can try to use the official sample in GitHub, and change the DeviceCapability in manifest into your device.

Also is there a log or something UWP Windows.Devices.XYZ logs to. I don't know whats wrong. As far as I can tell everything is good. Everything works in C++/Win32 and WPF/Win32.
