I was debugging an issue with a bluetooth gamepad, and found that its hid report descriptor had its hat using the following descriptor. I did testing with the latest version of InputSystem (1.19.0)

0xA1, 0x00,        //   Collection (Physical)
0x05, 0x01,        //     Usage Page (Generic Desktop Ctrls)
0x09, 0x39,        //     Usage (Hat switch)
0x15, 0x01,        //     Logical Minimum (1)
0x25, 0x08,        //     Logical Maximum (8)
0x35, 0x00,        //     Physical Minimum (0)
0x46, 0x3B, 0x01,  //     Physical Maximum (315)
0x65, 0x12,        //     Unit (System: SI Rotation, Length: Centimeter)
0x75, 0x08,        //     Report Size (8)
0x95, 0x01,        //     Report Count (1)
0x81, 0x42,        //     Input (Data,Var,Abs,No Wrap,Linear,Preferred State,Null State)
0xC0,              //   End Collection

This causes the following error (the stack trace is about 1000 lines long and just repeats this):

IndexOutOfRangeException: Index was outside the bounds of the array.

Changing the hat to a more standard hat does fix the problem however.

0x05, 0x01,        //     Usage Page (Generic Desktop Ctrls)

0x81, 0x01,        //   Input (Const,Array,Abs,No Wrap,Linear,Preferred
0xC0,              //   End Collection
