According to USB HID Specification, An item is piece of information
|
||||||
|
about the device. All items have a one-byte prefix that contains
|
||||||
|
the item tag, item type, and item size.
|
||||||
|
There are two basic types of items: short items and long items.
|
||||||
|
If the item is a short item, its optional data size may be 0, 1, 2, or 4 bytes.
|
||||||
|
Only short item is supported here.
|
||||||

|
||||||
@return Position

@param StartPos Start position of the HID item to get.
