CC2540: HID Keyboard by USB Dongle (Feature Report)

Hi to all

I'm trying to make a HID Keyboard via USB Dongle. I used HIDAdvRemoteDongle sample.

All things work well but my problem is working with "Feature Report". I changed entity0Desc (Keyboard report descriptor) in the "usb_hid_descriptor.s51" file to this one :

entity0Desc:    ; Keyboard report descriptor (using format for Boot interface descriptor)
	DB    0x05, 0x01                   ; USAGE_PAGE (Generic Desktop)

entity0DescEnd:

I tested my code by SimpleHIDWrite. Every time that I send Feature report , I receive invalid values in the EP0 (Data received in the one time USBF0 reading):

0xFF Sent => 0xFF Received

0x02 Sent => 0x7E Received!

0xFF Sent => 0xBE Received!

cc2540 code :

.
.
void usbcrSetReport(void)
{
// Received setup header?
if (usbfwData.ep0Status == EP_IDLE) {
if ((HI_UINT16(usbSetupHeader.value) == HID_REP_TYPE_FEATURE))  // Feature Report Received
output = USBF0;
.
.
.

PrintKeys(output); // Send output value as keyboard key(!!!) to windows

Why "output" value don't valid and don't match with sent value?????

I wrote a VC++ program that send a feature report , but there is an error .GetLastError return 31 (0x1F) [A device attached to the system is not functioning] and HidD_SetFeature return zero. why?????

VC++ code :

	buff[0] = 0; // ReportID
	buff[1] = 0x3; //Report Value
	res = hid_send_feature_report(handle, buff, 2);
	if (res < 0) {
		printf("Unable to send a feature report.\n");
	}

Sorry for my English language ;-)
