I have two older laptops (HP Probook 6550b) that we keep in inventory for our technicians to use older software tools on (HVAC control software). We keep them mainly because some of our older software does not like USB to serial adapters and these laptops have a physical serial port.
Anyway, I took these out of storage recently to update and get them ready for use. I noticed right away that none of the USB ports on the laptops worked (ive never tried them before). Mice, keyboards, thumbdrives, nothing worked. Windows made no visual or audio cues to show it was aware anything was plugged in. I noticed in device manager that there was an unknown device in the USB section. I did all the usual...delete/redetect, install chipset drivers, etc...but nothing worked.
I found on another forum that another user with the same issue on the laptop fixed it by forcing the driver to USB root hub. That worked on one laptop, i was able to use USB devices, even thought the unknown device came back on the next boot, but USB still worked. The other laptop still has no USB functionality.
Upon checking the details, I see "Windows has stopped this device because it has reported problems (Code 43). Problem is Im not really sure what device this is. Device description shows USB\UNKNOWN. Various other details show USB root hub, and no version of the driver seem to be correct. I was able to get the VID & PID from the other laptop, but PCI database and google only show it is an Intel device. Drivers from HP for that laptop and the Intel Driver Updater dont work either. Any ideas?
I don't know if this is related to the USB problem, but in the past whenever I've upgraded HP laptops to Windows 7, those errors in Device Manager have always been related to a CF reader or a biometric device that was missing a driver.

I did download and install that Intel driver installer, even though I have been through 3 or 4 others that all seem to work, just not for this one device. Upon installing this driver, Windows informed me that I had a unrecognized USB device (duh). Now instead of the code34, I have code 10 "the device cannot start."

I concur, I have seen stranger things. But seeing as the same exists on multiple machines, thats what makes me think it has got to be some kind of a driver issue, but all attempts thus far to fix it have brought up zero results. Ive pretty much thrown in the towel at this point. 2ff7e9595c
