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 (8.15.10.1825, 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
HKLM\SYSTEM\CurrentControlSet\Control\Class\{36FC9E60-C465-11CF-8056-444553540000}
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
