Allows you to view is no longer "PORTS (COM & LPT) in Device Manager as a category to expand and view the status of the different PORTS. This feature appeared, but now does not work. Traffic on the previous question is of no help. Brand-new thougts?
Hi John,.
Thanks for posting your question on the forum of the Microsoft community.
I would like to know some information about the problem so that we can help you better.
1. have you done any hardware or software changes to your computer?
2. What is the brand and model of your computer?
I would suggest trying the following methods and check if it helps.
Method 1:
Please follow these steps to display hidden devices.
a. Click Start and type cmd in the start search box.
b. right click on cmd and select run as administrator.
c. in the command prompt window, type the following command and press ENTER.
Set devmgr_show_nonpresent_devices = 1
d. type the following command at the command prompt and press ENTER.
Start devmgmt.msc
This action opens the Device Manager. Now you can check if the device appears in Device Manager.
If this does not help, then use method 2.
Method 2:
Check in the BIOS (embedded devices) if the COM ports are enabled and set to "auto".
Note: Change to the BIOS/complementary metal oxide semiconductor (CMOS) settings can cause serious problems that may prevent your computer from starting properly. Microsoft cannot guarantee that problems resulting from the configuration of the BIOS/CMOS settings can be solved. Changes to settings are at your own risk.
Then, if the problem persists, use method 3.
Method 3:
Please install the driver manually and check.
Refer to this article:

Comm port not detected by VISA / MAX after the device power cycle connected
I have a device communicating via USB virtual comm port. The device and labview program both work very well, most of the time. The program is designed for the automatic connection for the connected equipment. It works perfectly when I unplug and reconnect the USB cable.
However, if the unit power cycled as the USB cable is connected and the program/vi is running of things go wrong. The device enters a phase of boot loader for a few seconds to the power upward, if labview tries to query the port comm during this phase the comm port is corrupted in some way and is no longer recognized by VISA / NI MAX. However, other programs, hyperterminal, etc device manager can see and communicate with the port when the boot loader is complete. For Labview / NI MAX to see the port I have to physically disconnect the USB cable. The program does not need to be restarted in order to detect the port comm again and, infact, labview is restarted or my compiled program does not solve the problem. Physically disconnect the USB port allows visa / MAX OR see the port is connected.
It seems to me that there is a problem with VISA where somehow if a device is not correctly identified by VISA during the first attempt it just does not take into account the port until a physical intervention. Is there a way to force VISA to reassess completely all connected comm ports?
Hello MJanus,
As far as I know, most of the virtual com ports are not fully supported by VISA so some quirks in its operation are to be expected: http://digital.ni.com/public.nsf/allkb/6E1922B526572CB8862571AA00544057?OpenDocument
Officially, we do not support the use of com virtual ports, if unfortunately, the feature you have now is probably as good you'll be able to get with this configuration. I know it's not the answer you were hoping to hear and I apologize for the inconvenience, but it is not really possible visa work well with all software virtual com port due to the wide variety of products available.
Kind regards

Output Multipal Modem and Ports Com Usbs without deleting the driver...
In my laptop I don't connect to many cell phones, now my problem is my Ports none is going too far and I do not use affected old Ports so I tried to find Solution on Web... I Manage to find Solution but I stuck when it comes to too many Ports... I want to release too many Ports in a short way.
What I find Solution on the Web...
Run elevated command line Device Manager:
> set DEVMGR_SHOW_NONPRESENT_DEVICES=1 > devmgmt.msc
Turn on "Show hidden devices" in the menu and uninstall gray COM ports.
After the display of hidden devices, it's hard to uninstall devices one by one... I want to erase a single Type of devices in a single order without deleting driver device because my goal is to free Ports as much as Possible without removing the device driver...
Hello
Currently, removing the devices in the Device Manager is possible, one device at a time. This is because each device has its own corresponding entries in the system files and registry.
Kind regards.

Satelltie M40X: NIC disappears from the Device Manager
I have a Satellite M40X with Windows XP SP2 and my card (Realtek gigabit) network is no longer seen by Windows (or Linux: test performed with a Ubuntu live CD).
The lan card is not seen by Toshiba HW Setup. I disappeared 2 days ago, was back yesterday that a d is not present today...
LAN card is enabled in the BIOS.Can someone help me solve this problem?
The PC is 13 months (out of warranty Toshiba...)
Some registry keys are damaged and so the LAN card is not visible in the Device Manager (very possible) or the LAN card is damage (more)
I think you should try to reinstall the operating system. If after installing new network card is not visible in device (such as unknown device or network card) Manager then it s a bad material work and in my opinion, that the replacement or repair will help.

Advanced Port Replicator III more compatible with the Portege R200
I just ordered a new Portege R200 and above-port replicator... However, I note that the R200 is not listed in the list of laptops supported for this Replicator! Can anyone confirm if I have made a mistake and need to change the order?
Will be
I visited the area Options & accessories on the European site of Toshiba, and like you said the Portégé R200 is not listed in the list of mobile phones compatible.
So I assume that the Advanced Port Replicator III more (PA3474E-1PRP) does not support the protected R series. -
Read the serial number of the device in LabView COM port
Hello
Is it possible to read a device COM port number in LabView? I would like to make an initialization of the program following the right port COM of a device, for example a USB temperature reading device, and set the COM port as the correct port at the start of the main program of LabView. I want to do that, because a USB device gets usually different dedication of COM port on different computers. Our application runs on 80 different computers. A program like that would be very nice.
Can someone help me?
Paal
Another thought. It also has a place where certain standards can save you a lot of time.
You have 3 dongles by machine. When setting up a computer are these three dongles * always * assigned to, for example, com 3, com 4 and com 5.
Similarly, always check that instrument 1 is always on com 3, tool 2 is always on com 4 and 3 device is always on com 5.
This convention will also simplify debugging...

Hello world
I have three serial ports on our lab computers, one is the default on the motherboard port, and two others are usb connectors of the series. The problem is the default com1 serial port has a cross write in MAX and two other serial ports are missing. All serial ports displayed correctly in windows XP Device Manager and in the register too. The version of labview is 8.5.1 with NI-visa 4.4. See attached photos.
I have many hours of research and have not found a clue. Please help me.
Thank you!

Need to identify the designation of port COM through BACK...
I'm editting a program that sends and receives information to a device via a USB - serial adapter. Previously, the program has been run only on one pc which always use the same COM port when the device is connected. Scripts used with this program have been written to always specify this port. After having taken the device and connected to another pc, the pc allocates another COM port - this is a relatively easy task for me to go through the device management and identify the appropriate COM port, modify the script and get the device communicates with the pc. HOWEVER, in the future, communication must be maintained between the device and a laptop with any user.
The program you are using may open a windows command prompt and run DOS commands. If possible, I would like to help you find a way to use BACK to identify the COM port used by the USB adapter so I can assign this port number for a variable to be used in scripts, creating their infallible to any user.
Thanks for your time,
Chris

Hi, I'm pretty new to dreamweaver so excuse me if this question is stupid or the obvious answer.
I created my first project in dreamweaver - a "Coming Soon" page for my site Cyber Zombie Coming Soon! and I'm pretty happy with the results considering it was my first time using dreamweaver for a real project of myself without a tutorial. However, I have a problem with my navigation menu. When my site is displayed in desktop mode, the navigation is fine (screenshot)
But when I reduce the size of my window to represent a mobile , the button interface that is supposed to say "Turn the Navigation" is extremely difficult to see (screenshot)
When I hover over the button with my mouse, it's a little better but still difficult to see (screenshot) and also you do not have a mouse on a smartphone to get high with.
Is someone can you please tell me how I can remedy this. I need the button 'Toggle Navigation' to be more visible, but I don't know how do to change what I used a "bootstrap" navigation menu which had the button built in.
Thank you
Jason
