Hello everyone,

I tried to use

DeviceHandle handle = LibUsb.openDeviceWithVidPid(null,
            VENDOR_ID, PRODUCT_ID);

to handle my device, but the 'handle' returned null, so i cannot do write or read my device anymore.
Then I tried listing my devices (I already got the vip and pid from my specific device ) , and I reveived a message 'Unable to open device: Operation not supported or unimplemented on this platform. Continuing without device handle.'
can anyone help me please~~~ ?

OS: windows 10
Environment : java 8
Driver libUsbK(3.0.7)
IDE: eclipse
