We have the need to access a specific USB device from both the Linux and Windows platforms using C#, Java and possibly C therefore I am trying to develop a native library that can be cross compiled, on Windows and Linux, using Rust. This seems to
work well when I access the USB device within a test Rust Application. From this application I am able to write to the USB device and get the expected results back. When I link the DLL to a test Windows UWP application I am unable to
open the USB port and receive an “Access is Denied” error. I am linking the DLL to the test app as described here: https://social.msdn.microsoft.com/Forums/en-US/26013e5e-3ff1-44a0-8797-0474dabd12d0/uwpincluding-dlls-in-a-uwp-application-in-visual-studio?forum=wpdevelop
In the Package.appxmanifest file I defined the following capabilities:
<Capabilities>
<CapabilityName="internetClient"/>
<DeviceCapabilityName="serialcommunication">
<DeviceId="any">
<FunctionType="name:serialPort"/>
</Device>
</DeviceCapability>
</Capabilities>
These capabilities allow me to communicate to the device using the standard Windows UWP communication APIs however it does not seem to allow me to access the device from within the linked DLL.
Is it possible to allow a native library like this to communicate with a USB device when linked to a Windows UWP app?
Thanks
