Hi all.

Currently I am working with Custom HID example, the uC is STM32F107. Ihave changed the descriptor accordingly:

From:

/* Led 1 */0x85, 0x01,/*REPORT_ID (1)*/0x09, 0x01,/*USAGE (LED 1)*/0x15, 0x00,/*LOGICAL_MINIMUM (0)*/0x25, 0x01,/*LOGICAL_MAXIMUM (1)*/0x75, 0x08,/*REPORT_SIZE (8)*/0x95, 0x01,/*REPORT_COUNT (1)*/

To:

/* Led 1 */0x85, 0x01,/*REPORT_ID (1)*/0x09, 0x01,/*USAGE (LED 1)*/0x15, 0x00,/*LOGICAL_MINIMUM (0)*/0x25, 0x01,/*LOGICAL_MAXIMUM (1)*/0x75, 0x08,/*REPORT_SIZE (8)*/

0x95, 0x08,

/*REPORT_COUNT (8)*/

Can any tell me why I cannot send this report without error? When I set reportcount to lower than 8 everything is OK.
