Welcome to community! Can you give me a little more context around your scanner? Is it bluetooth? There is some known differences in player on browser and in the Tulip player for bluetooth barcode scanners, but this is something we are planning on addressing this quarter.
Fortunately, we’ve just fixed this issue as following:
We have defined a custom scanner in the player by using vendorID and productID of the device.
Now the scanner behaves in the player as expected .
