I2C errors appeared with multiple usb devices

Jump to: navigation, search

Hi Can we reproduce this phenomenon if we don't use USB Wifi? M3 USB2.0(CN5) <---> USB HUB <---> USB MEMORY * 2 and USB mouse dongle KF-M06(CN29) <---> CMOS camera(ov5642)

I cannot reproduce.(0/20) Could you try it on another KF board?

Thank you for the confirmation. Let me re-check with another camera module.
