I tried to use
DeviceHandle handle = LibUsb.openDeviceWithVidPid(null,
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~~~ ?
