Hi,
I have Aster carrier board with Colibry imx7s module and my USB keyboard (or mouse) connected to USB host port is not working. According to datasheet there is only one USB port on imx7s module. I tried to using both of the two USB ports (it should be the bottom one) on Aster board without luck. Unfortunetly there is no 5V between pin 1 and 4 on USB ports.
I am using default linux shipped with imx7s module: Colibri_iMX7_LinuxImageV2.6_20160630
Where is a problem?
