Windows 7: USB Root Hub Issues in RTM

USB Root Hub Issues in RTM

Hi there

I've been running various Windows 7 Betas and RCs on virtual machines and spare PCs for a while with no issues, so when I got access to the RTM I was quite confident (probably overly so) to upgrade my laptop from Vista.

Right after the install (ironically enough, from a USB), everything was working fine, until I plugged in my iPod, which installed the apple driver successfully, then informed me that the device was unplugged before the USB Mass Storage driver installed (it wasn't). I proceeded to try the other three USB ports on my computer (all four worked fine in Vista, and still work fine in XP and Ubuntu). None worked. I tried a thumb drive with an internal LED, and it appears that the device receives power for about half a second, before cutting off. Running a system restore back to whenever they were last working fixes the problem, I can plug in a USB stick, and it works fine for a couple of minutes, then its useless again.

The chipset is an Intel GMA965 express series, using the most recent driver (, for RC1). I've tried rolling back to the Vista driver, and the Vista driver in compatibility mode, to no avail.

Additionally, I've tried uninstalling all of the "USB Root Hub"s in the device manager, and scanning for new hardware, and uninstalling all of the USB controllers and then scanning for new hardware, still no luck. The issue that windows gives is

"Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)"

For which a fix for a similar problem (albeit with CD/DVD Drives) in XP was to delete the registry key, so I navigated my way to
And was first told access is denied. I took ownership, fixed permissions, and it still refused to delete (although, in trying to check what exactly the error message was, it just deleted now, although I'm not hopeful it will help)

I've disabled every reference to USB power saving mode in every power profile.

Most recently, I've tried the most recent Intel Device Chipset Installer, which installed successfully, but makes no difference. I also tried the built in troubleshooter, which recognises the issue, reinstalls all the drivers, and tells me it works/doesn't work, and then either way, it doesn't work. Although the troubleshooter does identify if there is a device plugged in for two of the four USB ports, it tries to install drivers, and fails.

In searching the internet for the last few days, I haven't been able to find a solution (although I have found several people with similar problems, one the same, all of which unsolved)

I would really prefer not to do a clean install - the reason I upgraded in the first place was because I had far too many programs installed to make it worth reinstalling all of them. I'm open to downgrading to vista, if its do-able with a clean.

I've attached a screenshot of the device manager, which may or may not be helpful (16 color gif to save space/time). Any help would be greatly appreciated, if available.

Thanks in advance

Just a follow up post to say I solved the problem.

If anyone else with the same problem should stumble upon this topic, my issue was a conflict with LibUsb-Win32, which I had installed in Vista in order to have my PS3 controller usable in Windows.

Yeah, I had the same issue too trying various methods to get my DS3 to work, and now I use the MotioninJoy driver.

wow thanks

i registered here just to post this thank you! I too had that driver installed for the ps3 gamepad (which did work great in vista, btw).

I used add/remove programs to uninstall the driver program (libusb-win32). it uninstalled in a few seconds, and by the time I alt-tabbed back to device manager, the usb hub drivers were installed and all my USB devices were detected.

THANK YOU! You saved me doing a fresh install (which would have fixed the problem but I never would have figured out the problem).

Fix USB Hub Code 19

Had this issue on a customer's computer with Windows 7 Premium 64-bit. I had been "Google-ing" solutions for a few hours and found yours. The customer did not have the PS3 drivers installed, but I did end up finding an alternative solution.

Numerous "solved" articles for "Code 19" ended up being just for CD/DVD problems only, but if you follow the directions and substituting the USB Root Hubs registry key for the DVD ROM registry key, thats what solved it for me!

NOTE- Editing the registry can cause serious compute problems.

Start Registry Editor (Start, Run, "Regedit")
In Registry Editor, expand My Computer, and then expand HKEY_LOCAL_MACHINE.
Expand SYSTEM, and then expand CurrentControlSet.
Expand Control, and then expand Class.
Under Class, click {4D36E965-E325-11CE-BFC1-08002BE10318}.
((I had multiple entries with the same name, but if you go through the list they will say DVD, Keyboard, USB, etc... at the top))
In the details pane of Registry Editor, on the right side, click UpperFilters.
On the Edit menu, click Delete.
Click Yes when you receive the following message: Are you sure you want to delete this value?
The UpperFilters registry entry is removed.
Exit Registry Editor.
Restart your computer
