4.3 USB
The uX presents itself to the Host computer as a Human Interface Device (HID).
In HID devices, the attached device instructs the host computer what the report
format looks like via a “Report Descriptor”. The uX defines only a single write and
a single read report type. The uX Write (commands to the uX) and Read
(responses from the uX) reports are both 64 bytes. The USB report acts as a
data transport. No data formatting is done at the USB layer, data must be
correctly formatted as described in section 5.3 prior to being placed in the report
buffer. Note that for long messages the total message can span multiple buffers,
and it is possible that multiple messages can be present in a single buffer.
Unused bytes in write reports should be filled with zeros. Unused bytes in read
reports will be filled with zeros.
4.3.1 USB Driver Installation
The Windows USB Human Interface Device (HID) driver is included with the
windows operating system. The driver should automatically install itself when the
uX is first connected to host computer. It should appear in the device list (in
device manager) as a Human Interface Device. The exact nomenclature may
vary depending on the version of Windows used. For Windows 7 it appears as a
HID-Compliant device as show below. (Note that the uX must be attached to the
USB and powered up to appear in the device list).
It can be verified that this is the uX by right clicking on the device, and choosing
properties.
