Hello! I try to make USB host using FRDM-KL25Z but it has some
problem to attach multi-interface USB keyboard.
I installed USB Stack v4.1.1 and CWv10.4.
I have gaming keyboard and multimedia keyboard which have two
interface in a single usb device. If I connect it to the PC, it install two keyboards.
Anyway I programmed USB host on the FRDM-KL25Z like below in a ProcessorExpert.C.
Made two keyboard tasks.
...
_usb_event_init(&USB_Keyboard1_Event);
_usb_event_init(&USB_Keyboard2_Event);
...
for(;;){
if(keyboard1_hid_device.DEV_STATE != USB_DEVICE_IDLE) {
Keyboard1_Task();
}
if(keyboard2_hid_device.DEV_STATE != USB_DEVICE_IDLE) {
Keyboard2_Task();
}
Poll();
}
...
In a Device_driver.info.c
const USB_HOST_DRIVER_INFO DriverInfoTable[] =
{
{ // Keyboard1
{0x00,0x00}, /* Vendor ID per USB-IF */
{0x00,0x00}, /* Product ID per manufacturer */
USB_CLASS_HID, /* Class code */
USB_SUBCLASS_HID_BOOT, /* Sub-Class code */
USB_PROTOCOL_HID_KEYBOARD, /* Protocol */
0, /* Reserved */
usb_host_hid_keyboard1_event /* Application call back function */
},
{ // Keyboard2
{0x00,0x00}, /* Vendor ID per USB-IF */
{0x00,0x00}, /* Product ID per manufacturer */
USB_CLASS_HID, /* Class code */
USB_SUBCLASS_HID_BOOT, /* Sub-Class code */
USB_PROTOCOL_HID_KEYBOARD, /* Protocol */
0, /* Reserved */
usb_host_hid_keyboard2_event /* Application call back function */
},
{
{0x00,0x00}, /* All-zero entry terminates */
{0x00,0x00}, /* driver info list. */
0,
0,
0,
0,
NULL
}
};
But it does not working properly, for gaming keyboard, Only Keyboard2_Task() working properly. When i press more than 6 keys at the same time KL25Z does not working any more until reset the MCU.
I think the usb host stack may some problems to initiate multi-interface USB device.
Below is the logo message when attach the 2-interface keyboard usb device to KL25Z usb host.
