USB 3.0 Description
When you want to flash the OS image firmware into the LeMaker Guitar EMMC nand flash, you need connect the Guitar to PC. Or when you want to debug the Android APP on Guitar, you also need connect the Guitar to the PC. At that time, the LeMaker Guitar is acting as a device of PC, so the USB 3.0 will work as device mode. But currently the USB3.0 device mode low level driver has not finished development, so when you use it as device mode, it will switch to USB2.0 device function automatically.
You can use a "USB 2.0 Micro-B Plug to USB 2.0 Standard-A Plug" cable like this to connect LeMaker Guitar to PC:
|USB2.0 Micro-B Plug to USB2.0 Standard-A Plug Cable||Guitar USB2.0 device mode|
You can also use a "USB 3.0 Micro-B Plug to USB 3.0 Standard-A Plug" cable like this to connect LeMaker Guitar to PC (also will act as USB2.0 device function):
|USB3.0 Micro-B Plug to USB3.0 Standard-A Plug||Guitar USB3.0 device mode|
The host mode may be more useful than device mode, because most of you will use the USB3.0 to connect the hard disk or 1000Mbps ethernet adapter. When you want to use the USB 3.0 Micro-B Receptacle as the host mode, you need a USB 3.0 Micro-B OTG cable (USB 3.0 Micro-B Plug to USB 3.0 Standard-A Receptacle ) like below:
