MS-4X Imager Us
er Manual
USB HID Interface
Microscan HID Report Format
Size: 64 bytes, fixed-length. The USB HID standard defines all reports as being fixed-length.
Structure: REPORT ID (1) LENGTH (1) DATA (62)
Values in parentheses indicate the size, in bytes, of the field.
Field Descriptions
REPORT ID
Size: 1 byte
Value: 0x01
Note: Report ID is the method employed by USB HID to allow multiple report formats to be
sent and received from the same interface.
LENGTH
Size: 1 byte
Value: 0-62
Note: Length indicates the number of valid data bytes in the fixed-length data field. This is
necessary because the USB HID standards define HID Reports as fixed-length, yet the
imager or host may require a smaller data size in any given report.
DATA
Size: 62 bytes, fixed-length
Value: 0x00 to 0xFF
Note: The Data field is left-justified, meaning it begins immediately after the Length field.
All unused data space is NUL (0x00) padded. Data values can be “binary”, meaning that
they span the entire 8 bit range of 0x00 to 0xFF.
