Table 9. Controller Status Request
The direction bit in bmRequestType has been set to 1 (device-to-host) to return the status
report.
The byte bRequest is set to 6 to indicate that this is a Controller Status request.
The controller does not use the wValue and wIndex fields. These fields should be set to
zero to ensure future compatibility.
The wLength field indicates the size of the Controller Status report.
Response
When the request is processed, the device returns a Controller Status report.
The device stalls endpoint 0 if the request cannot be processed successfully. This would
happen if the report length requested by wLength does not match the controller status
report size.
This report contains information describing the status of the controller. The report sent is
determined by the size specified in the wLength field of the Status Request.
All multi-byte quantities in this report are sent LSB first.
Standard Format Status Report
This version of the Status report will be sent if the EX compatible driver asks for the 8-
byte Status report. This version is simply the first 8 bytes of the controller Status report.
EX Controller Status Report
This version of the Status report is only compatible with the EX USB controller. This
version is sent when the larger (20-byte) Status report is requested.
