For the folks who needs to use the DS9208 (or any other Zebra scanner), the only solution to make the scanner works on UWP/WinRt is to switch to Serial emulation using the sdk app sample. Then you can filter Serial devices using the UWP/WinRT framework and get the Zebra. You'll have to check inputBuffer of the device every X seconds. There isn't DataReceived Event for Serial devices.
Could you solve it ? i have same question
