• Driver files that run the parallel port and USB port

  In the system information utility where to look to find the parallel port and the port driver USB, name of file that manages these?

  Know the drivers specific, is only half the story.  Why you looking for these drivers?  You have problems with your parallel port or USB port?  This can be caused by problems with drivers or it could be a hardware problem (hard to diagnose a hardware problem without good parts to swap and test).  If you need to update the drivers, you must use device (not msinfo32) Manager - or maybe clicking on an executable file that loads the drivers automatically (depends on how it is sent by download).

  Go to the Device Manager by going to start / find and type Device Manager and enter and then double-click on the program icon that appears.  Check each device to a red x, yellow! or white?  These identify devices with problems probably (drivers, but also of conflict or something else).  Click on each for more details and troubleshooting tips.  If you need drivers (I assume that you want to the parallel port and USB ports), get the computer dealer or the manufacturer of the device (NOT of Microsoft Updates).  In fact, you must disable automatic updates in Windows Update driver as follows: http://www.addictivetips.com/windows-tips/how-to-disable-automatic-driver-installation-in-windows-vista/. Follow these steps to get the drivers: http://pcsupport.about.com/od/driverssupport/ht/driverdlmfgr.htm.  Once you have the drivers, you can install them via the Manager device as follows: http://www.vistax64.com/tutorials/193584-device-manager-install-driver.html.  Or run the Setup program of driver provided by the vendor of the computer or the manufacturer of the device.  Be VERY careful get Vista compatible drivers for these devices are difficult to identify (they usually come with the numbers of model or something like that if they can have serial numbers) and using the wrong drivers could make the problem (whatever that is) worse.

  If you update the drivers succerssfully and the problem persists, then it is probably a hardware problem.  In this case, contact the manufacturer of your computer for technical support (hopeully it is still under warranty) or bring it to a professional computer repairman (NOT Geek Squad or one of those big store centers because they don't really know what they're doing and charge a lot for this level of expertise) to have the components tested and possibly replaced.

  I hlpe that aid.

• HP Pavilion P2-1140 does not have a way to connect to a Firewire port and USB transfer is not supported by Windows 7 to connect the Sony HC20 Handycam.

  Original title: Sony Hanycam HC20

  I just bought a HP Pavilion P2 - 1140 W7 64 bit and may not know how to download video from my Sony Handycam HC-20 who

  using a Firewire connection. P2-1140 does not have a way to connect to a Firewire port and USB transfer is not supported by Windows 7.

  I looked in the spec of my card mother HP and there is no additional slots to add adapters, no PCI, PCI-e or anything that looks like

  as if you can add anything. I know that the Firewire to USB converters cable do NOT work, any suggestions please

  There are USB firewire converters, but I think it will be a situation of hit or miss--they are unable to work or perform very well.

  The only option I can think of that would work would be to use AV out on the camera and a USB capture card that records on the computer.
  You can also consider going back to the computer and get a different model that is built in firewire support or at least an extension connector in order to get an expansion card.

• Pavilion a6120n: USB ports and slots memory card does not

  My Pavilion a6120n desktop computer has worked brilliantly since I bought it. Since last week the 2 front usb ports and 2 unused usb ports in the back have stopped working. My printer is plugged into a rear port and my wireless mouse is plugged into a second rear port and these work very well.

  I use usually a USB key for the exchange of data or card reader locations (which have also stopped working). I no longer see memory card icons in the window 'computer '. When install something again the "new hardware found" statement appears, but the driver install always fails. I think it's a software problem, but there is no usb drivers to download on the HP/support site that I can find... so...

  Here's what I've tried so far.

  Run antivirus software. Full scan & scan memory - no problem

  Don't scan complete malewarebytes - no problem

  I tried to reboot several times without success.

  Catering to several previous = failure restore points

  Computer restart in repair = failure mode

  Use the repair disk I did = failure

  Control the management of the power supply for each usb port see if power was properly routed = ok

  Removed the cover of the housing and carefully inspected the cables and connectors.

  Finally I tried to uninstall the drivers usb = failure

  After restarting the computer the last time that the boot file has failed, and after several hours of attempting a repair, I had to reinstall Windows 7 completely.

  Still no usb or memory card function.

  Any help would be appreciated

  Thank you

  OK, after a lot of frustration and a reflection to when the problem started. I discovered it all started when I installed my new HP Envy 4500 printer all-in-one. It has wireless capabilities, but I installed it via a usb cable.  I just didn't know it would be the problem but I started with this premise.

  I got all components usb of the computer (except the mouse at the moment). So I uninstalled all the usb drivers I had on Device Manager.

  After restart, drivers loaded automatically and everything works fine now. I see my camera via the connection cable, the work now in sd slots and all the work of the usb.

  I left the 4500 want connected and installed the printer with the network provided on the installation disc software. I test printed from my computer and iPod so far, and it still works properly.

  I did have to reinstall Vista. Could it have been a glitch in the installation of the software want to through the usb cable? Don't know and don't care at this point. Just happy that everything works.

  Thanks for the comments, and I consider this problem to be solved.

• remove the adapter write protection and usb/microsd card

  Put a micro sd card into the adapter and since I opened it I'm impossible to delete files, format the drive e., Cup etc. When the drive is disconnected Ican manipulate the files which have been locked with the drive connected. The share in the properties of the drive button is untouchable and I tried some tools to format the troubed drive and nothing has worked so far. It affects all my usb ports no matter where I connect the sd adapter. How can I change the access point so E is not write protected?

  There is a little switch on the side of the SD card. Make sure that it is upward, to the terminals.

  Hello

  I recently used a sierra on Satellite A200 computer laptop data card and devices Bluetooth is to share with the data card com port and lead to the client cannot find the data card.

  I tried the data card in lenovo t61 and another computer laptop manufacturer, all of them are working properly.
  The question seems to casue of the Satellite A200 laptop.

  Everyone meets it or advice please!

  Thanks in advance!

  Hello

  The data card Sierra uses the same ports com as the internal module of BT?
  Well, in this case, you have an opportunity:
  You can assign the different port com on the data card Sierra

  Check if this is possible in the Device Manager.

  On the other hand, you can try to install first the data card Sierra, then BT stack
  Perhaps it would be too much work
