   Hi!

I got j5040 motherboard ,several days ago.
I tried to install Ubuntu,but I could not.
I tried low level format to USB memory and SSD,however could not run.
Many USB errors occurred.
Finally I pulled out one memory, and succeeded install Ubuntu.

So I found memory control is too bad.

 IANNO

	I have new J5040-ITX board. 1. I connect front panel cable to USB_0_1 connector on the board. Additional usb ports work OK. 2. I disconnect the panel above and connect additional usb ports cable to USB3_0_1 connector on the board. Again, additional usb ports work OK. 3. I connect both of them together. The computer boots, but none of the 4 additional usb ports work properly: - bios/uefi interface does not detect bootable usb flash drive in any of these 4 ports; - windows 10 says "device not recognized" trying to use any of these 4 ports. In brief: both connectors work alone, but they do not work together. I also have J5005-ITX board. It behaves the same. How can I make it work?
