I have a few usb 3.0 sticks: ADATA ue700/64GB rated R:200MB W:100MB, Lexar S33 16GB/32GB R:100MB W:variable.
When i use my sticks in 2.0 ports, no issue, everythings fine. But, when plugged in 3.0, no matters the stick, they disconnect after 1-20 sec of transfert.
Updated my 2 USB controllers firmware with fw found on asus website. No change.

Hi Krogan, and welcome

Have you tried different USB3 ports? I recommend using the Intel USB3 ports - the front panel or the connections just under the ethernet socket. Those have worked well for me.

Do you mean that you removed USB boost? That's often a good thing to remove.
