disable asmedia usb 3.0 extensible host controller bios

I do know that USB 2 has separate drivers.USB 3 has its own on each ' USB 3 Root Hub'.check that it does.Īre you sure the other USB 3 ports ARE functioning to their fullest? My experience was, using an external USB 3 dock, I was only getting 105MB/sec. Asus may not be up to date on that USB 3 driver and you would need to go directly to the site of the company that makes the port for them. Mine was from 'Fresco Logic' and ,coincidentally, it updated itself just yesterday through the Windows 7 update process.

Each USB 3 port should be using a specific driver, just for the USB 3 function alone. not sure what you mean by 'monitor' software. They work flawlessly plugged into USB2.0 ports.

They are formatted in MBR, so not certain if that makes a difference. I planned on using the two Seagate USB3.0 drives for exports and I cannot get them to work while plugged into the main USB3.0 ports on the back of the Motherboard. I also went into windows power settings and disabled USB Selective Suspend. Other settings I have played with: I disabled USB3.0 Legacy support in the BIOS. I am using the latest drivers from ASUS, windows doesn't have any auto-installed drivers, and I also see 2 items in my startup list called USB3.0 monitors by Renesas Electronics Corporation. It seems to me like it is a driver issue, but there are no other USB3.0 Drivers. If I plug USB2.0 devices into the USB 3.0 plugs - those items work fine. If I plug the 2x 3TB backup drives into the USB 2.0 slots, everything works just fine. I have one unknown device in the device manager. My Kingston USB 3.0 card reader also is not recognized.

I plugin my 2 Seagate 3TB external drives and after awhile they aren't recognized any more (this is after a fresh, up to date driver install and re-setting the bios). The USB 3.0 ports on the front of the PC work just fine. They work just fine with USB 2.0 devices though. Been searching for help on this issue for awhile, and just went through a long RMA process with ASUS only to find that the issue still exists.īasic problem - The USB 3.0 ports on the back of the motherboard will not work in with USB3.0 devices.
