[SOLVED] Allwinner D1H USB host

Hi all,

I’m really stuck with the make working USB host in Allwinner D1H BSP and RT-Thread. 
Now USB host can detect device connections, but communication has not started.

Executed at hardware such as [ClockworkPi DevTerm R-01](https://www.clockworkpi.com/home-devterm) and [Sipeed Lichee RV + Dock](https://wiki.sipeed.com/hardware/en/lichee/RV/Dock.html). Inetention is make workable USB keyboard in DevTerm device.

This is my GitHub repo: https://github.com/ylyamin/RT-Thread-on-Allwinner-D1H
And explanation in more detail: https://github.com/ylyamin/RT-Thread-on-Allwinner-D1H/blob/master/documentation/D1_6_usb_keyboard.md

#### 1) Firstly I used existing sunxi-hal:

rt-thread/bsp/allwinner/libraries/sunxi-hal/hal/source/usb/host 
Created driver rt-thread/bsp/allwinner/libraries/drivers/drv_usbh.c:

```c
int drv_usb(void)
{
    hal_usb_core_init();
    hal_usb_hcd_init(1);    
}
INIT_DEVICE_EXPORT(drv_usb);
```

RTT console output:

```shell

Seems is detect USB device connection but communication and enumeration did not happen.

#### 2) Then I try to use HAL from D1s Melis OS

https://github.com/Tina-Linux/d1s-melis/tree/master/ekernel/drivers

I moved this usb HAL folder to RTT:
rt-thread/bsp/allwinner/libraries/sunxi-hal/hal/source/usb_melis

Original RTT USB HAL folder moved to:
rt-thread/bsp/allwinner/libraries/sunxi-hal/hal/source/usb_old

Is can be compiled and run Melis USB HAL, but also nothing really happen:

[usbh core]: adding sub dev  (config #1, interface 0)[I/DBG] usb match id suceessfull
```

Looks like exchange descriptors but I believe is an exchange with a virtual device not real.
Seems is detect USB device connection but communication and enumeration did not happen.

#### 3) Then I try just using only clock and phy initialization from HAL:
 
```c
    hci_clock_init(sunxi_ehci,ehci_table);
    open_clock(sunxi_ehci);
    usb_passby(sunxi_ehci, 1);

hci_clock_init(sunxi_ohci, ohci_table);
    open_clock(sunxi_ohci);
    usb_passby(sunxi_ohci, 1);  
```

And for EHCI/OHCI stack try to use [TinyUSB package](https://github.com/RT-Thread-packages/tinyusb):

```c
int drv_usb_tiny(void)
{
    init_tinyusb();
}
INIT_DEVICE_EXPORT(drv_usb_tiny);
```

Re-route interrupts to TinyUSB:

```c
irq_no = 49;
request_irq(irq_no, ehci_handler, 0, "ehci", NULL);

irq_no = 50;
request_irq(irq_no, ohci_handler, 0, "ohci", NULL);
```

RTT Console output:

```shell
msh />usb_tiny
phy write: 4200810<-0

```

In this case, TinyUSB EHCI stack can detect USB line connection but can't start communication.

#### 4) Also looked to Linux

https://github.com/smaeul/linux/tree/d1/all
To implementation linux/drivers/phy/allwinner/phy-sun4i-usb.c
Seems to me clocks and phy init are quite the same as in RTT sunxi-hal. So I don't know what i should fix in sunxi-hal to make it work.

Maybe someone expert in Allwinner D1H USB stack can help with it, please ?
