So. I have this beautiful Maximus V Formula. It's nice. However, been having this issue with it. Actually, it's not an issue with the board as it happened on my old Maximus IV Extreme...which is why I'm stumped.

My USB3 is very hit and miss. I have a wide range of USB3 devices from different brands and they all suffer from the same issues. Keep in mind I never have them all connected at once:P

So let's start with the issue that bothers me the most. I have two USB3 external drives. They both work absolutely fine. However, at BOOT, one of them goes into "compliance mode". It's random as to which one, but it always happens to one of them at boot. I can turn it off and turn it on and it works 100% fine after that until the next reboot/boot. Windows recognizes that it's there at boot, but all it says is "USB Compliance Mode" in Device manager for status. I've tried everything. Different ports, updating firmware and drivers (from station-driver), updating motherboard BIOS etc. Nothing corrects it. This ONLY happens with USB3 devices (which my external seagates are). They don't do this when plugged into USB2 ports.

Also, in general use USB3, if I plug a USB3 flash drive, or a 2.5 inch USB3 external drive in to any USB3 port and say...start copying a big file, it stops working and disconnects. Works fine if I plug it into a USB2 port, though. Does this on every device I have, EXCEPT (and this is the confusing part) the drives above. When they are both recognized by Windows, they work amazingly. Keep in mind, these same USB3 devices work in USB2 ports perfectly fine...but I don't want USB2. I didn't pay for USB2.

I thought it may have been my board, but nah, happened on my old IV Extreme as well, and I have a hard time believing that all my USB3 devices, that range from Kingston to ADATA to Lexar to Seagate are all going to have the same issue.

Can ANYONE offer any sort of insight? lol
