    USB Devices not seen in Windows 7


    I just installed Windows 7 in a new system for my mother. In the past she was using Windows XP. We used to backup her photos by inserting a USB external HDD to the computer and copying files to it. Now with Windows 7 I am having trouble doing this.

    I plugged the same 3.5in USB external HDD into a USB port of her Windows 7 system. Immediately a bubble popup was seen that said drivers were being installed for the new device. Eventually a message also stated that the drivers were installed and device was working properly. BUT.......

    But, there was no drive listing for the device in Windows Explorer. I could not access the drive.
    The drive is powered by the USB, and it was spinning, with a red LED lit on the device to indicate power.


    I had a similar issue with the HP Printer PSC 1200. It installed drivers automatically and said the device was working properly. BUT...
    But, the device was not in the list of printers when I attempted to print.

    Another USB Device, a Logitech QuickCam works OK though.

    Device manager shows no errors for the USBs and I have used the FS USB for flash drives with no problem.

    looking for insight!

    Thanks

    Have you restarted the machine?

    Have you run Windows Update (WU)? Updating Windows might help or it might find a printer driver.

    Have you tried different USB ports?

    Any chance the new machine has USB 3.0 ports? They often (always?) require drivers.

    What does device mgr show with the HD and printer connected?

    If your OS is 32 bit, just select that in drop down box on the HP site

    Can't tell what bit depth your OS is - please follow the EZ System Specs link in my sig. You'll have to manually add the make and model of the PC. click on any post "My system specs" to see how other member's machines are described. The tool in the link does most of the heavy lifting though.

    Also, it will help knowing the make and model of the ext HD

    Thanks

    Yes, WU were up-to-date as of Dec. 29th 2013

    With the printer I tried both USB 2 and USB 3 adapter card....no difference.

    There are USB 3 Ports in the back that I installed and added the drivers for...they work fine
    The Card Reader/USB device in the Front also had drivers installed for it.

    Not sure I checked the USB HDD in device mgr with it connected. The printer shows up in device mgr and has no issues.

    Thanks, was hoping something simple might resolve the issue - time to dig deeper.

    Try this: SFC /SCANNOW Command - System File Checker

    Run Option Two in the the tutorial three times (SFC works in small chunks)
    restarting the machine between each

    run it multiple times even if it reports no integrity issues
    after the thrid execution, follow Option Three in the tutorial and post sfcdetails.txt

    The system is Windows 7 X64
    HP does not provide drivers or software for this...Windows 7 supposed to do this.
    It's my mother's system now, was mine prior to some upgrades.
    The HDD I will have to check with them on it...

    Oh boy...this will be tough. I will see if I can walk my mother (77yrs) through this. Wish I could get remote access working with her.

    It might be better to "take it into the shop" -> by that I mean bring mom's machine to your place.

    Yeah Windows Update should find the drivers, it depends on
    your driver update settings, and
    if Windows "sees" the device (DevMgr sees them - right?)

    I gave you the link directly to the manufacturer's driver page. By downloading and installing the driver yourself, you eliminate that as a cause, at least for the printer.

    Yes, with respect to the printer HP does not supply the drivers, Windows 7 does...and it did find them and it does show up in device manager, but when attempting to select the printer, no listing exists.

    My mother lives 3hrs from my house. What I can not talk her through I will have to wait till I make a trip there in a month or two.

    It's good to know that there is a forum that is fairly quick to respond.

    Thanks

    I again suggest that you use a local offline pkg to reinstall the printer.

    Probably best to uninstall what's there, reboot, and use the downloaded HP pkg to install the device.
