Hi there.

Let me start off by saying that my problem is specific to only windows 8.1 64x and deals with usb devices. 

My specs:

• Crucial MX100 ssd
• Win 8.1 Pro 64x
• MSI Gtx 970
• MSI Gaming 5 z97
• i7-4790k

I'm trying to connect my Rocksmith Realtone cable (usb audio) to a usb port on my pc and whenI right click the "Usb audio device) in device manager, this pops up under properties. There is also a yellow exclamation mark on the device.

"

This device cannot start. (Code 10)

The I/O request was canceled."

Now, like I said, this is only on win 8.1 64x. I installed win 7 64x on an older hdd and put it in my pc and the cable was recognized right away and was usable. I have tried:

• Manually uninstalling the device, and reinstalling
• Manually installing the device driver
• Formatted ssd and did a fresh install of win 8.1
• Tried it on win 7 with same pc and it worked fine
• Updated realtek drivers
• Updated Nvidia drivers
• Disabled xHCI in bios
• Disabled legacy usb support in dios
• Disabled eHCI in bios
• Enabled usb powered hubs in bios
• Disabled selected powering in power options + made a new high performance profile

Every other usb device I have/try works. I tested all my usb 2.0 and usb 3.0 ports and they all work with my mouse, keyboard, and flash drive.

I'm not really sure where to go from here. I contacted Ubisoft (maker of the game Rocksmith) and they said it was a driver issue and I haven't received any more help. I'd really rather not need to dual boot win 7 and win 8.1 just to  use the cable.

I don't have a powered usb hub, but I have set the value for Enhanced power management to "0" for the device, and turned off selective power saving. I have also ready that thread many times. 

Also, this only happens for Win 8.1, so I know it's an issue with the OS

The USB Audio device is, like I stated, the rocksmith cable. I have contacted Ubisoft but they are unable to do anything and say that "the drivers are the generic usb mic drivers from Microsoft". I know of many people who have Win 8.1 and are able to use the cable flawlessly. In fact, everyone I know who has it and win 8.1 has it working.

I just tested the cable on my Win 7 64x laptop and it worked fine
