(Low-speed Device Cable and Resistor Connections) 高速识别 USB全速/低速识别相当简单,但USB2.0,USB1.x就一对数据线,不能像全速/低速那样仅依靠数据线上拉电阻 位置就能识别USB第三种速度:高速。因此对于高速设备的识别就显得稍微复杂些。 高速设备初始是以一个全速设备的身份出现的,即和全速设备一样,D+线上...

I recently designed a board with reference to SuperSpeed Explorer Kit Schematic.pdf. The cyusb3014 is connected to the PC via the USB3.0 port but nothing happens. I'm sure that the voltages of VDD, U3RXVDDQ, U3TXVDDQ are normal. The FSLC(pull down to gnd) and PMODE(F11)...
Please refer the below D+/D- normal and abnormal waveform, we find if we use low speed device to do the hot plug several times, the system will random can’t detect the low speed device, and this issue only happened at the USB port with TUS...
If you don't charge Apple with an official charger, such as Samsung charger, or through a computer's USB, the charging speed may be too slow or even refused to charge, then you can plug into the upper USB port to speed up the charging. Note that 1A charger is impossible to output ...
