Standard Enhanced Pci To Usb Host Controller not running
Hello,
I'm shortly after doing service pack 1 cleanup, having the following problem:
USB devices are not recognized, are not working at full speed, or are being newly installed.
Looking to devmgr I found there are many USB devices having the ! icon over it, moreover I believe that the culprit of all this mess is this driver
Standard Enhanced Pci To Usb Host Controller
not running at startup.
Don't know why and how is that related to SP cleanup procedures, however after removing this device and several new hw rescans I get as this controller as other USB devices recognized and probably working properly.
Any help how to force this controller be running at startup so that all USB devices are identified properly?
Standard Enhanced Pci To Usb Host Controller
Driver version: 6.1.7601.17514
Driver timestamp: 21.6.2006
I've made proof that if I restore drive to state before SP cleanup, all USB devices are started flawlessly.
I think this is related record in event log for this problem:
EventID: 219
Source: Kernel-PnP
Failed to load driver \Driver\usbehci for device PCI\VEN_10DE&DEV_0AA6&SUBSYS_1CF71043&REV_B1\3&267a616a&0&21.
If I try to open this registry key
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\PCI\VEN_10DE&DEV_0AA6&SUBSYS_1CF71043&REV_B1\3&267a 616a&0&21\Properties
I get error message: access denied
Maybe the problem?
Help..
