New to this forum. I just completed a recent build and am having problems with a couple of USB devices causing the system to freeze. Before going further, here are the components:


ASUS M5A99FX PRO R2.0 (BIOS 2005)
AMD FX-8350
G.skill F3-14900CL8D-8GBXM
Windows 7 Pro 64 bit
Samsung 840 Pro MZ-7PD256BW 256GB
WD Black WD1003FZEX 1TB 7200 rpm
XFX Double D FX-787A-CDFC Radeon 7870 GHz Ediction 2GB
Creative SB X-Fi Titanium HD
ASUS DVD-ROM DVD-E818AAT OEM
ASUS Blu-ray Burner BW-16D1HT
Netgear WNDA3100v2 USB wireless adapter
Koutech IO-RCM630 Card Reader USB 3.0
Rosewill Tachyon-1000 1000w power supply
Corsair Obsidian 650D case
Canon MP620 printer
Microsoft x4 Sidewinder keyboard
Razer DeathAdder mouse

The RAM works as advertised at 1866, 8/9/9/24/T1 and 1.5v. Nothing is overclocked. But I am having a problem with certain USB devices freezing the system. The system runs fine with the mouse, keyboard, and wireless adapter in place, and I can access my wireless router and internet just fine, and the speeds are good. After I plug in the printer (win 7 64 bit drivers), the system freezes. If I reboot (which I have to do by holding down the power button), the wireless adapter cannot access the router and the diagnostics tell me the wireless adapter is having hardware or driver problems. If I leave the wireless adapter out, then there is no issue with the printer. I tried plugging the wireless adapter to the USB 3.0 port on the card reader to see if it was unique to the 2.0 system, but that also freezes the system if I connect the printer to one of the USB 2.0 ports. If the printer is not plugged in, then the adapter works just fine.

I have ordered a PCIe wireless adapter to see if that fixes the problem, but can anyone tell me if it is a USB conflict I am seeing, or if it is perhaps the wireless adapter (or its driver) that is causing the problem? Or is there a change in the BIOS I could try? The driver for the USB wireless adapter is win7 64 bit, also. Also, for what it is worth, the system does not unfreeze if I unplug the network adapter.

Also, all of the devices were plugged into the USB ports on the rear of the computer when using USB 2.0. When I tried the 3.0 plug, that was the only one on the front of the computer (card reader, driven by USB 3.0 header on the motherboard).

Any help would be greatly appreciated.

Thanks,

Brent
