• Problem with the unknown device - Code 43

  This USB controller has no drivers. It indicates the Version of the driver is 6.1.760.17586.

  I tried to disable and uninstall it with other USB controllers, but he returned as a unknown device vacuum.  This means that I can not connect devices to ports 3 & 4.  I am using Windows 7 32 bit.

  I'll be grateful for any advice.

  Thank you

  Andy

  This means that the other usb ports on the PC work, if so it looks more like a problem of internal connection with these two ports

• Problem with an "unknown device" having an impact on the performance of the pc

  Hello world! My name is Lorenzo, and I am currently having problems with my laptop, a HP Pavilion dv6, 64-bit laptop running Windows 7 that runs more slowly.
  At first, I thought that the problem was a malware, so I decided to follow this procedure: http://www.techsupportalert.com/content/how-know-if-your-computer-infected.htm.
  I tried TDSSKiller, Comodo cleaning Essentials, Killswitch, Malwarebytes, Hitman, Combofix then I installed Driver easy to update the drivers but it doesn't change anything.
  Even repairs Windows or Windows Fix it does not solve the problem.
  This is the message I get from Tune Up Utilities: Windows reports the "A2 Direct Access Driver Support disk" device does not work correctly.
  When I open the Device Manager and try to manually update the device it doesn't seem to work; the same thing happens if I disable it or uninstall it and restart.

  Well first, uninstall the update of the pilot program, using such will only cause problems. Drivers for your laptop are available free of charge at HP, nore if you use windows update for drivers.

  And then uninstall Tune UP utilities because it is only likely to cause other problems. Win7 contains all of the built-in tools in order to maintain the system.

  The "A2 Direct Access Support disk driver" part of Emisoft Anti-malware, you have this program installed?

  And in the future do not try to update something on that you don't know anything

• Problem with the PnP device

  Problem when I connect to my camera Canon SD870IS.  Has started to occur after Windows has been reinstalled, using the disc had been slipstreamed with SP1.  Convenience store (Start-> devices) and printers-> right click and select Troubleshot reports there is a problem with the PnP device and suggest to reinstall the driver. Reinstall driver fixed the problem, but he returns as soon as the computer is restarted.  How can I permanently solve the problem?  Environment:
  Dell Inspiron 530
  2 GB memory
  latest drivers for system devices (drivers have been updated since the problem began, that does not solve the problem)
  latest drivers for the camera
  Windows 7 Ultimate 32 bit

  I carefully reread the manual of the camera, which proposed the transfer of the camera rather than the computer.  After doing this once, the problem has been resolved.  Apparently, initiating the camera change some settings on the computer.  It shows now no error when the camera is connected, and the file transfer Wizard starts automatically.

  Problem can be closed.

• Cannot use Skype download message problem with the recording device.

  I used the following steps to detect the problem:

  (a) I uninstalled the existing version of Skype

  (b) installed the new version of Skype

  (c) check if the problem still persists. Given that the problem still persisted.

  (d) consulted the sound link in the Panel control, updated sound card driver software.

  Hey,.

  When I use any usb device in my computer it didn't show. When I troubleshoting the messege see the problam pnp device. kindly advice me how to solve this problam in my system.

  Thank you.

  Original title: pnp device problam

  Hello Usman,

  Thanks for posting your query in Microsoft Community Forum.

  1. It was working fine before? If Yes, you did it any significant hardware or change software on the computer before this problem?
  2. What is the exact error message you get, when you say, 'messege see device pnp problam?

  I understand that you can not use your USB devices because your system does not detect them. To resolve this problem, I would suggest trying the following methods and check if the number is reproduced.

  Method 1: Try running the Fixit tool from the link below.

  Hardware devices do not work or are not detected in Windows:
  http://support.Microsoft.com/GP/hardware_device_problems

  Also, run the next fixit to solve common problems with USB devices.

  Diagnose and automatically fix the Windows USB problems

  http://support.Microsoft.com/mats/Windows_USB_diagnostics

  Method 2:

  Remove and reinstall all USB controllers.

  1. Open Manager devices by clicking the Start button, click Control Panel, click system and security, and then, under System, clicking Device Manager. If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.
  2. In the list of the categories of equipment, locate and expand Bus USB controllers.
  3. Right-click every device under the Bus USB controllers node and then click Uninstall to remove them one at a time.
  4. Restart the computer and let the USB controllers get reinstalled.
  5. Plug in the removable USB device and test to make sure that the problem is solved.

• Problem with the Modem devices: Modem already used or not properly configured

  I use windows 8. Until last night, my laptop was working fine, but now it rejects all the modem devices, I try to plug it. I tried to connect to internet via Auntie photon and reliance netconnect +, but this message "Modem already in use or not properly configured" keeps on appearing two modem devices? Is there a problem with my OS or my laptop? Help, please

  Thanks for the solution.
  Well, my problem was similar but different too. The method to uninstall the modem device is correct. I tried, but still it did not work.
  My problem was that I have 3 different modems installed on my pc, but I used one of them. So I would uninstall only one I used. It turns out that we have to uninstall all modems. Its pretty simple, but its not so obvious. I thought about it later in like 2 days. I hope that people reading this don't have to wait 2 days to fix this problem.
