| // This file contains definitions for the USB function test driver. |
| // The driver implements three endpoints: bulk out, bulk in and interrupt. |
| // The driver supports: |
| // |
| // 1. Writing data to the device with USB control request. |
| // |
| // 2. Reading data back from the device with USB control request. |
| // |
| // 3. Requesting the device to send an interrupt packet containing the data |
| // sent via USB control request. |
| // |
| // 4. Looping back data via the two bulk endpoints. |
| |
| // USB control request to write data to the device. |

| // USB control request to read badk data set by USB_FUNCTION_TEST_SET_DATA. |
| #define USB_FUNCTION_TEST_GET_DATA 2 |
| |
| // USB control request to request the device to send an interrupt request |
| // containing the data set via USB_FUNCTION_TEST_SET_DATA. |
