А что это за структура?
Я передаю и в IPINBuffer И IPOUTBuffer
указатель на иодну структуру:
TSetupPacket = packed record
bmRequest : UCHAR;
bRequest : UCHAR;
wValue : Array [1..2] of UCHAR;
wIndex : Array [1..2] of UCHAR;
wLength : Array [1..2] of UCHAR;
End;
TDescriptorRequest = packed record
ConnectionIndex : ULONG;
SetupPacket : TSetupPacket;
Data : Array [1..2048] of Byte;
End;
в коде вот так :
ZeroMemory(@Packet, SizeOf(Packet));
Packet.SetupPacket.bmRequest := $80;
Packet.SetupPacket.bRequest := USB_REQUEST_GET_DESCRIPTOR;
Packet.SetupPacket.wValue [2]:= USB_DEVICE_DESCRIPTOR_TYPE;
Packet.SetupPacket.wLength[2]:= 1; // Èñïîëüçîâàòü áóôåð 2 Êá
// GetDeviceInfo(hHost);
//IOCTL_USB_GET_DESCRIPTOR_FROM_NODE_CONNECTION
Success:= DeviceIoControl(hHost,?????????,
@Packet, sizeof(Packet),
@Packet, sizeof(Packet),
BytesReturned, nil);
If not(Success) then begin
// Log(Format(' Îøèáêà ïîëó÷åíèÿ èíôîðìàöèè îá óñòðîéñòâå %s', [ //SysErrorMessage(GetLastError())]));
Exit;
End;
а потом Packet.Data разбираю...
