I/O error at boot up and probable faulty USB Root Hub on Main. Board
If I had not attempted to the upgrade to Windows 8 Pro.,
I would not be aware of this problem and the fact.
“If It becomes necessary,” I cannot do a re install of windows 7 Pro.
And I cannot Upgrade to Windows 8 Pro.
The reason:
Upon boot up from Windows 7 or Win 8 purchased DVD
the following.
“Windows encountered a problem communicating with a device connected to your computer. This error can be caused by unplugging a removable storage device such as an external USB drive while the device is in use.
Make sure any removable storage is properly connected and then restart your computer.”

As mentioned in my earlier posts, I was attempting an upgrade to
Windows 8 Pro from my current O/S Windows 7 Pro 64 bit.
That is what brought this major issue to my attention.
It's important to understand that with my current install of
Windows 7 Pro 64 bit - "everything" functions perfectly.
No problem with boot-up - No problem with using the repair
DVD I created during a system image backup.
No problem using that repair disk to recover a backup image.
No problems when Windows 7 is up and running.
Further to that. Device Manager shows no conflicts and all attached
drives appear in Disk Manager as they should.
Tests:
RAM test OK - Drives OK - Cables OK - DVD Burner - OK 750 Watt PS OK
Video Card OK - All CPU temps below 105 F. M. Board Temp 89.6 F.
After a lot of testing and research:
I believe the problem is at USB Root Hub - USB1112 and USB910
located at the bottom edge of P7P55D-E-PRO mother board, regardless
of the fact, all the USB ports function when a flash drive or external
HDD is attached.
That said, there is an issue.
A pop up message recently began to appear that reads
“A USB device as not recognized.” That happened over and over
until I removed the external HDD and disconnected the adapter and cable
running from USDB1112
Deduction:
As mentionedearlier , only when booting from a Windows 7 or 8 DVD
a black screen appears with the following message.
“Windows is having a problem communicating with one of the devices attached to this computer. This error can be caused by unplugging a removable storage device such as an external USB drive while the device is in use. Make sure any removable storage is properly connected and then restart your computer.”
I/O Error 0xc00000e9
End of black screen message:
It is then, and only then, that this issue comes to the surface and stops an upgrade of Windows 8 or re install of Windows 7.
In my opinion, If a USB Hub has hardware issue it can ruin your
day or give you a reason to buy a new mother board due to a fault
in the USB hub(s)
