Windows 7: New USB HD Unknown Device problem

16 Dec 2010   #21

Win 7 Pro 64bit
Problem fixed

Well, I tried one other thing I was told to try and it worked.

I unplugged all USB devices from this box and then I powered down. Rebooted it, and powered down again, but this time while it was down I unplugged all the power from the box. According to one of the mods from ASUS the MB reset all the USB configs to zero. Now it reads all my SD cards, external drives, and otherwise works just fine. No more "yellow triangles" in the device manager or unknown devices. Maybe this could help some other person. I do hope so. This was bugging me to death. One thing though. Why does it say amd64 in the Architecture? As I said before that is pretty odd.

Good luck guys oh and have a great holiday and new year!

I recently put a USB 3.0 PCI card in this box and added a WD My Book 3.0 1TB drive. I did a BIOS revision as well. I wasn't having any real problems but I did notice it going to sleep periodically. The drive is working but it isn't being recognized. I put a desktop icon of it on the desktop and if you click it NOTHING, you can only access it by going into "My Computer". These messages were after I did a scan.

"Windows has stopped this device because it has reported problems. (Code 43)".Problem with PnP devices Detected (little yellow triangles)
There are problems with some PnP devices. Windows will take additional steps to further troubleshoot these devices.
Detection details
Windows Version: 6.1
Architecture: amd64 . (This is an Intel i7 chip whats up with that?)

Anyway. It shows the device in the control panels as a "Unknown Device" This sound familiar to any of you? I thought the "Architecture: amd64" was really odd since this is an Intel based chip and MB. Here is my hardware settup.

Thank you for any help you can come up with!
