# Specification of the 048d:5711 Integrated Technology Express, Inc. GIGABYTE Device
|
|||
|
|
|
|||
|
|
#### Structure description
|
|||
|
|
|
|||
|
|
**USB control transfer used**
|
|||
|
|
(and usbhid 🤓)
|
|||
|
|
|
|||
|
|
Endpoint: **0x00**, Direction: **OUT**
|
|||
|
|
* bmRequestType: **0x21**
|
|||
|
|
* bRequest: **9**
|
|||
|
|
* wValue: **0x03cc**
|
|||
|
|
* wIndex: **1 (0x0001)**
|
|||
|
|
* wLength: **64**
|
|||
|
|
* Data fragment: as described below. Trailing zeroes trimmed in this document however must be defined within actual data interaction. Therefore 'wLength: 64' is imperative'.
|
|||
|
|
|
|||
|
|
In libusb semantic:
|
|||
|
|
```
|
|||
|
|
unsigned char message[64] = { 0XCC, 0X60, }; // example 'cc60'
|
|||
|
|
int returned_value = libusb_control_transfer(dev_handle, 0x21, 9, 0x03cc, 1, message, 64, TIMEOUT);
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
Endpoint: **0x80**, Direction: **IN**
|
|||
|
|
* bmRequestType: **0xa1**
|
|||
|
|
* bRequest: **1**
|
|||
|
|
* wValue: **0x03cc**
|
|||
|
|
* wIndex: **1 (0x0001)**
|
|||
|
|
* wLength: **64**
|
|||
|
|
|
|||
|
|
In libusb semantic:
|
|||
|
|
```
|
|||
|
|
unsigned char buf[64] = {};
|
|||
|
|
int returned_value = libusb_control_transfer(dev_handle, 0xa1, 1, 0x03cc, 1, buf, sizeof(buf), TIMEOUT);
|
|||
|
|
```
|
|||
|

**NOTE:** input values below marked with prefix "INPUT << "
|

|

|
|

|
|
Interaction could be split on three phases: Application startup, command transmission, ending
|
|||
|
|
|

|
|

### Commands
|
|||
|
|
|
|||
|
|
NOTE: Переходы между изменениями цвета в sync режимах идут без следующих пред-последовательностей. Но переход от отдельных к синхронизированному - через стандартные ппоследовательности
|
|||
|
|
|
|||
|
|
There are two types of commands:
|
|||
|
|
* syncronized - applies same setting to everything
|
|||
|
|
* separate - adjusts settings separately
|
|||
|
|
|
|||
|
|
***Commands sent before actual directive. Structure is always the same***

|||
