I'm working on emulating a keyboard with an rpi, but for some reason writing b'\xe3\0\0\0\0\0\0\0' to hidg0 is pressing the left shift, ctrl, alt and meta keys when it should theoretically just press the left meta key.
I'm getting this information from the https://www.usb.org/sites/default/files/documents/hut1_12v2.pdf on page 59 where it shows that the keycode for left meta is 227, which in hex is xe3
