Z87-GD65 USB and ATA/ATAPI Bridge Issues

[stamos.adam]

I just installed a new Z87-GD65 into a Silverstone HTPC case and I'm having weird issues with all USB 3.0 ports. This problem occurs on both a Windows 10 technical preview install and a Windows 8.1 install. Everything is updated including the BIOS and, as far as I can tell, installed properly. I used Live Update 6 to verify the integrity of the motherboard drivers and BIOS version. I also double checked the build for any potential shorts or incorrectly plugged in devices and everything seems to check out.

Basically, what seems to be happening, is the computer is constantly losing connection with the USB 3 ports and is re-"scanning" to gain connection again. This makes all the USB 3 ports useless for any media or storage device and is extremely annoying when used with a mouse and keyboard. This "re-scanning" if that is what it is, is also causing all the i/o ports to freeze for a second or two so if I let's say, double click on a folder and this "scan" occurs, it takes a few seconds for the the folder to open. I also notice that a storage device plugged into any USB 2.0 port is more sluggish than usual and there is an overall delay in all mouse/keyboard input. This is a new motherboard and a new build although I have used all this external equipment and some internal with another computer with no issues at all.

System Specs:

PSU: 850w Coolermaster with front panel fan control
Motherboard: MSI Z87-GD65
CPU: Intel i5 4670k
Video Card: MSI GTX 770
RAM: 16GB of G-Skill Sniper series memory
Storage/Media:
128GB Samsung SSD (OS)
2x128Gb Crucial SSD Raid 0 (Games)
1TB Western Digital black (general programs)
2x2TB Western Digital Green (storage)

I also have a Medisonic 4-bay USB 3.0 enclosure with 3x2TB drives and one 3TB drive.

If this is a Windows issue I'll re-install Windows 7 but if this is a hardware/driver issue I'd like to know how to fix it if possible as I can't return or exchange the board.

Does this happened in the BIOS, too?
Only USB 3, USB 2.0 won't losing connection but always sluggish?

Try clear CMOS and reinstall your USB driver again?
also you can try to disable XHCI/EHCI Hand-off settings in BIOS, sometimes this would fix the USB problem.

what particular USB device will show the USB disconnection in USB 3.0 port?

did you tried to simplified the problem by just using first your Samsung SSD (with OS) and remove first all other HDD including the Medisonic first?
also try to use the Onboard VGA first if problem persist to test.

just hope that this is not the Samsung SSD issue as I personally encountered problems with Samsung SSD before that causes unstable issue
and changing my SSD to another brand fixed this issue.

Everything works, or is at least detected, fine in BIOS. I already messed with the hand off settings and no dice.

I got tired of dealing with it so I formatted an installed Win 7 unfortunately the problem is still there. It's much less pronounced so I can actually use the computer without the weird freezing and stuttering issues but any time I try to transfer and or unzip any large file windows will lose connection and I'll get a "USB device has Malfunctioned" error. This does not happen on my other PC, unfortunately I need the hard drive bay on this PC.

Have you tried it outside of the case to see if the same thing happens? Maybe you have something shorted on the case unintentionally and that is what is causing the problem.
