Hi
I think installing the proper drivers for your motherboard and operating system should work.
Find your drivers here (scroll down to see the available drivers and make sure you install the drivers for your operating system) or on the cd that belongs to your motherboard.

hi, see if you have installed any new devices/hardware to see if its conflicting, often grafics cards conflict usb devices, also just check that in the setup(when you boot up)that the usb ports have not been disabled or usb keyboard support hasn't been enabled/disabled. good luck!!

Have you gone into device manager to see it the USB ports are active? Try this go to device manager, remove the USB ports from the list of devices, then restart the PC, the system should recognize the USb ports and reload them and their drivers, you can also go to HP support on the net and email there support, it is free for life and they really know there stuff.

Better uninstall the driver file completely and once again install the driver file from the Hp website with proper updates .

Also check whether that particular port is blocked (the port which says cant find driver ).

This is usually caused by a faulty USB handshake. The two most common causes are bad contact (i.e. bad USB port or cable) and interference inside USB hubs, especially the externally powered ones.

You can (usually) solve the problem by disconnecting the cable, waiting for the USB disconnect sound, and reconnecting the cable.

The real solution of course is to correct the hardware problem (which might be as easy as using another USB port, or as difficult as having the scanner replaced -- even if usually the problem is external to the device).

HP Laserjet 1012 printer not recognized


I really don't understand your problem as you stated it.!!
Your printer worked on your old system.. What was your old system ?? XP, XP Pro., 32 bit or 64 or VISTA. VISTA home 32 or 64.
If you are having problems installing the printer, it is not the fault of the Manf., you may not be loading the correct drivers.
First, check your device manager and see if the printer is being seen. Next, go to your printer icon and remove any printers installed.
Next, disconnect the printer from the unit and reboot.
Now, you have a unit free of any printer entries.
Find the software for you printer and if it is the correct version software for your printer, install it.
During the installation the software should tell you to plug in the device to a USB port.
Make sure the port you are using is the same as you have used before, as you may not have the support needed with another USB port. example,
port in the front may be a USB 1 port, the USB ports in the rear may support USB2 devices.
Next, if the software has loaded correctly and you have had no problems during the installation, you should be able to run your printer.
You should be able to find the correct drivers for your printer @ hp.com
I hope this has helped you !!!

The only other solution other than rebooting is to remove the cable from the usb port and reinsert it. Sometimes the computer will recognize the drive and it will work properly.

External Harddrive Ignorance...


I've seen this happen with hubs being connected to external hard drives before.

Do you have a free usb port on the back of your computer you can plug it into?

That should fix the problem.

USB port problems with hp printer


There are few things to remember using USB.
  • If your System is in hybernation mode, don't remove any attached USB device, because it will damage your USB driver. This is one of the known problem from microsoft.
  • If you have to remove any USB device use 'Safely Remove Hardware'.

To remove currepted USB drivers its not enough to remove your printer drivers.
  1. You should un-install the 'Universal Serial Bus Controllers' from Device Manager.
  2. Then re-boot to clean registry.
  3. Install the 'Universal Serial Bus Controllers' using XP Setup CD.
  4. Then check the Mass storage, PDA etc, it should recognized by XP.
  5. Then install printer driver (don't attach printer to system untill setup finish or setup says to connect).

I think it will fix.
Please let me know your feed-back.

Thanks
