windows cannot start this hardware device code 19

I should point out that this process does not work except in safe mode: If I try, it seems to reinstall the hubs correctly, but shortly go back to code 19. I ever went as far as to attach any and all USB devices I have, allowing them to be detected, uninstalling their drivers and detecting them to reinstall working drivers. Repeating the process of uninstalling and scanning for the devices fixes these also, and I was able to access data on external hard drives, and use my usb keyboard and mouse again.

This causes all the USB Root Hub listings to correct themselves, and the attached devices to reappear (with yellow triangles of their own).

The one which does not give this error is notable as in its properties, its location is listed as 'on Standard Enhanced PCI to USB Host Controller', while all others are 'on Standard OpenHCD USB Host Controller'.įollowing the advice I found elsewhere, including the official microsoft response ( here) I restarted windows in safe mode, went into the device manager and uninstalled the USB Root Hub listings and scanned for hardware changes. In the device manager, all of the 'USB Root Hub' listings (except one) have a yellow triangle and error code 19: 'Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged.' I recently upgraded from Vista 32-bit to Windows 7 32-bit and have run into an issue with my USB ports.īasically, if I plug any device (notably a USB pen drive) which requires automatic installation by windows, all of the devices attached to USB ports go dead.
