Win 7 and 64-bit USB adapters

Background: Service mobile organization using more than 100 different pieces of software among more than a dozen OEMs to program various electronic communications / equipment.  Portable computers used in the field all have standard RS-232 ports of series 9 pins, each of the various equipment has an intertface cable used to read/write settings.  It takes a truckload of these cables...
In any case, as it becomes increasingly difficult to find new laptops with a serial port, and very recent material is now accessible via a USB port, use adapters USB-to-Serial, blah, blah, blah, etc..

Person in charge of the engineering drivers & dongles seem to understand that "RS - 232" is a STANDARD and that signals to the 9-pin end of the adapter must conform to this standard... that the driver is the software interface between the operating system (whatever it is) and the real world (RS-232).
Without mentioning name, software of all manufacturers performs equally well on Win XP and earlier via a real serial port.
The problems arise when using laptop computers WITHOUT serial ports, having only USB ports.
Each equipment manufacturer has attempted to provide a "fix" by offering a pilot & cable adapter USB-series of interconnection of existing facilities.  They ignore requests for information on patches for stuff earlier saying "is not available" or referring to him as 'legacy' products... and then suggesting that we keep "of older computers" for such problems.
In the "old days", the settings of the connection in series has been configured by the user... 8-N-1-9600, etc..
The OS is much smarter today... we have "plug & play"!  Problem is that we have now five adapters USB/serial, five pilots, and tries to do an any of them work properly on Windows 7 is a challenge.
Here's THE QUESTION - Windows 7 Will allow loading several drivers (they don't have the same file names to condition) for these different adapters, then match the driver appropriate to its adapter expected when one of the cards is connected to the laptop?  Tech readers to a site, open good software to access the customer equipment, plugs in USB-serial adpater, hope for the best... He uses a 64-bit Dell.  What we have done so far is to load a driver for a given map, use it, remove this driver in order to load another one for a different application.  This STINKS!
As we hear, "plug & play" depends on the OS see the item plugged in, receiving a little stream that contains the element 'ID' and then knows what to do next.
What we're doing wrong?  We should change the brand of deodorant?
Thanks to all those who confuse through this.

  • Install an SSD in an Inspiron 3650 I7 6700 16 GB Ram 2 TB hard drive Amd R9 380 graphic and running Win 7 Pro 64-bit

    Hello:

    I have the above referenced PC and want to add an SSD (boot with OS drive).  I would like to make this my c: drive ssd.  I want to keep the Windows 7 operating system.  I made the disarmament recovery disks I opened the PC.  I don't want to win 10.

    Could someone with their infinite knowledge teach me throughout the procedure with pictures if possible?  What parts do need me if any?

    Thanks in advance

    Tom

    I thought I was doing a 512 GB SSD.  The system came with Win 10 Pro 64 bit installation floppies, but I'm used to and prefer to use Win 7.  The idea of cloning seems interesting.  In fact, it looks to the ticket.  What cloning software is recommended.  The priority of the boot in the BIOS change after cloning?  I am concerned with what type of SSD should I purchase (interface, transfer rate, etc.), what cables, if any, and which adapters will be necessary?

    At work, I have all my computers run with SSD (OS/startup) and they run like rockets.  This new computer runs great, but with a SSD for the start, program files, "scratch disks", I'll be in the drive hyper.  I'd be in Mary for a bargain price.

    Yet once again, thank you very much for you answer quickly.  I have several Dell optiplex computers in office and did not have a problem.

    Thank you once again to Osprey

  • I use win xp pro 32 bit and want to update for win 7 pro, how can I do? I have

    Hi I bought a new PC and need to upgrade all these years I was with win XP pro 32 bit, I need to switch to Win 7 pro. 64 bit...
    what I have to buy a new copy of license or just pay the amount of the upgrade to the new version of windows? If so how do I do that?

    You will need to purchase a new license, unfortunately, you can't buy just the product key, you'll need to buy the package, given that Microsoft is no longer selling just the key.

    Full version-

    Microsoft Windows 7 Professional

    Version upgrade-

    Microsoft Windows 7 Professional upgrade

    The upgrade to Windows XP?

    Please read these instructions carefully and completely before you begin installing Windows 7: there are important steps that you must follow to upgrade your PC from Windows XP to Windows 7 in order to preserve your files and settings.

    Before you begin, you'll need to backup all your data to an external storage device, and you will need all the installation discs for the programs that you want to keep. Please make sure that you have an external hard drive (see details below).

    More detailed instructions are available at windows.microsoft.com/upgrade-windows-xp. Here are the basic steps.

    1. start Windows Upgrade Advisor (windows.microsoft.com/upgradeadvisor) to see if there are known issues that may affect the installation and the question of whether you should install the version of 32 or 64 bit Windows 7.

    2 back up your files and settings on an external hard drive using Windows Easy Transfer (windows.microsoft.com/windows-easy-transfer). If you do not have an external hard drive, you will not be able to use Windows Easy Transfer. Alternatively, you can copy the files you want to keep on a USB stick, CD or DVD.

    3. you will need to manually reinstall your programs, such as Microsoft Office, after I installed Windows 7. Gather the installation for your programs and all partner/license product key discs. You may be able to download programs from the Internet. For example, Windows Live Messenger can be installed from the download.live.com/messenger.

    4. Insert the Windows 7 DVD in your PC. When asked "which type of installation you want. Click on "Custom (advanced)."

    5. when Windows 7 is installed, use Windows Easy Transfer to restore your files and settings.

    If you are not comfortable Windows 7 installation, check with a local retail or the services of the PC company store to see if they offer upgrade services.

Using Win 7 Pro 64 bit machine. I tried several printers and I can test printing from other applications such as Outlook and Wordpad.

    None of this has worked. I have to get rid of the error (0 x 000022) and he got good printing. I did clean the Adobe Reader DC machine, reinstalled drive XI 11.0.10 and in the preferences to disabled Adobe protected in Security (Enhanced) Mode and set "view documents I have PDF/A mode" forever in the Documents tab...

    It seems that each player version as it becomes more complex (with the "features enhanced security") gets more unstable.

    I'll try Adobe Reader DC when I eventually have to WIN 10 which is never if all goes well.

  • want to download win vista business 64 bit and we my 32-bit key, where could I find

    The product key on the label of COA affixed to your computer (in the battery on some laptops) is the same for 32-bit and 64-bit.  However, there is no place to download a Vista Business .iso file.  You can contact the manufacturer of your computer for help, but OEMS are not required to provide copies of 32-bit and 64-bit of their recovery software.  Once a customer chooses one or the other platform is usually all that he has the right to.  Check the manufacturer's Web site to see if the recovery software can be ordered both ways.  If this isn't the case, you may be stuck.

  • CPQ 2100 Error Msg PXE E61 but when disc is removed and connected to USB all is OK. Win XP

    I have a laptop old but used very useful - Compaq Presario 2100.  He had wind Xp on it.  I tried a system recovery using the recovery CD something was wrong.  Now, I get the error message.  System does not recognize the CD Rom or hard disk.  I removed the hard drive and use a usb adapter to connect it to another system.  The disk formatted and checked very well use sea Seagate tools.  When I put the drive in the laptop, I get the same error.  The drive is a Seagate 40 GB model ST 94011 A.  Is there anyway to make it bootable from another system, and then reinstall it in the Compaq.  I don't know why it does not recognize.  It does not appear in the bios. No idea what went wrong and how I can not get the drive recognized again.

    Hello:

    This error means that the PC can not find the hard drive (no boot device), it is not be seen in the BIOS.

    You have the error because the last thing that the PC has attempted to boot from was the network card and of course, there no device connected start there either.

    My assumption would be that the drive controller on the motherboard has conked, since you know the hard disk works.  Or the hard drive has an unspecified problem.

    Even if you were able to load the operating system on the drive from another PC, which will not make the hard disk appears in the BIOS.

    You have a known portable work hard drive that you can test to see if it can be recognized in the BIOS?

    Permission on Vista are configured in this way.

    Problems of permission and security with Vista/Win7, check the following settings.

    All the users who are allowed to share need to have an account on all computers that they are allowed to connect to.

    Everyone is an account, that means a group of all users who already have an account now as users.

    Using the functionality of all saved the need to configure authorization for each of the established users, it does mean not all those who feel that they would like to connect.

    Users who do not have an account on the computer are not part of the Everyone group.
