• No virtual USB port printer and device option think its an IEEE 1284.4 print media device

  I read a number of threads and can still not my problem fixed.  I have a Dell box running Windows XP SP3 and tries to connect to a printer of labels Zebra GX420t via a USB connection.  He was not to recognize the printer and I think I inadvertently he associated with the generic IEEE 1284.4 printing support driver.  I really need a usbprint driver.  Now, whenever I connect the printer, I get the yellow symbol in the Device Manager and I do not know how to change the driver to a USB driver.  I plug the printer even in my Windows 7 box and it uses a virtual USB port and the same thing happens when I plug it into my laptop running XP SP3.  No virtual USB port is an option on my desk.  Any thoughts?

  Just to close this thread...

  I ended up using the original XP Pro disc to 'fix' the corrupted files.  It was a disc of SP2, so I had to make all the updates to get back to where I was.  NA not losing all the data (which was nice).  Once all updates have been made, I plugged the printer without loading all the drivers and loaded.  Looked in Device Manager and it was listed as a USB Printer Support under USB device.  When I looked in the server properties/Ports, there was my virtual USB device I was hoping.

  I finished loading the drivers updated from a 3rd party (Seagull Scientific... well known for printer drivers label for most of the large manufacturers) and then deleted the old set to the top.  Once again, everything is good.

  Other corrupted files, I can't explain it all.  I had already reloaded the USBPRINT.sys and the USBMON. DLL and that didn't fix it.  Glad everything is good.  All else fails, start over.

  Thanks for the help.

• HP Deskjet 3545: hp deskjet 3545 my desktop pc does not connect to the printer via the usb port

  Hello

  I installed all the drivers and the software correctly and the printer can communicate with my desktop pc for problem analysis, but when I open an editor like notepad, word, write something in them or when I open a photo and when I try to print, it cannot communicate with the printer. I used same HP print and Scan Doctor in order to study the problem by clicking on the button "Correct the impression", in the program, he sees even my connected printer (usb) or same (LAN), but printing HP and Scan doctor after reviewing all the steps and ticks as ok, when he said "try to send the test page" and when he tries to send it to the printer It does not send and I choose "no print" to see which program will thus be, discover the program this time said "send the in-house test page", and I chose this option to send it internally and the printer works. The program says "there is a problem which can not find this application for assistance. try to uninstall and reinstall the drivers as an adviser"but I uninstalled and reinstalled the drivers and seems that there is no error, or any problem with the drivers, but seems that it cannot connect to the printer, even if I can use the scanner of my office and it connects to the printer without problem. What can be the problem? How can we solve this problem? any help would be appreciated. Thank you. Windows XP Professional Edition, 32-bit SP3 is installed on my desktop.

• virtual serial port? Vista 64-bit, usb, palm 755 p verizon dongle

  I have a new Vista 64 bit operating system and I'm having problems that everyone else is still.  Can't hotsync using the cable.  I bought the dongle bluetooth (Kensington) that many have said works.  My phone recognizes the PC.  My instructions on the phone that warm using bluetooth synchronization tells me to set up a virtual serial port.  The instructions are not very clear.  This is where it falls apart for me.  Can someone explain how to configure this virtual serial port?  Thank you.

  Well, I'm pleased to announce a successful solution.  On the recommendation of some other son that I left and piece and ioGear GBU321 Bluetooth USB key and Setup was a snap and it works (although SLOOOWLY compared to a connection cable, a while and plug your treo during your first sync).

  To setup you do the following (and this can also work for your Kensington):

  • Insert the driver CD
  • Insert the dongle when asked.
  • Install the drivers
  • Pair your device.  Basically, go to the configuration Bluetooth on the Palm screen and select "Trusted Devices".  You will find the bluetooth adapter, select it, and then the Palm or PC will provide or ask a pairing code.  The instructions will guide you through, but basically, you'll want to make sure that the same numbers are registered on both screens (this prevents you from accidentally pairing with some random near the computer)
  • This will actually set up your virtual port for you.
  • You can go to the hotsync Manager and click on "serial" and select the port created in the pairing process.
  • If you don't know which port has been created "Control Panels" and select "Phone and Modem" (assuming that you are in "Classic view").
  • Click on the modem tag and you will see something like 'Standard Modem over Bluetooth link' and next to that it will be the assigned port.

  I hope this helps.  I know that I was relieved not to have to trash my Palm or my PC (although when the Pre or iPhone with a physical keyboard comes out all bets are open)

• How do troubleshoot you a USB virtual COM port?

  Object

  Send orders of Labview to an Arduino board using the Advanced Serial write and Read.VI.

  The problem is that no orders are received by the Arduino.

  However, I can use the Serial Monitor built into the Arduino IDE to send commands to the Arduino and get the required result.

  I checked baud rate, the designation of COM port and the command is a simple as string 600,0.  The VI shows no error message.

  So, I'm looking for suggestions on how to troubleshoot a USB virtual COM port.

• virtual serial port (offered by a USB device) may not be reopened once the device has been lost and reconnected

  To connect to a virtual serial port offered by a USB device.
  -Physically disconnect the device (disappears from the entry in Device Manager)
  -Reconnect the device. (It reappears in the Manager of input devices)
  -Close the file handle
  -Reopen the virtual serial port. --> the CreateFile() call always fails with "ERROR_FILE_NOT_FOUND".
  -After dis - / reconnect the USB device once, the serial port can be reopened

  Even the true return of GetDefaultCommConfig there yet in CreateFile().

  It is clearly bad habits, because in our case the disconnection/reconnection occurs due to a restart of the device; and it's quite embarrassing to explain buyer for the disconnect/reconnect the device.

  Is there another workaround solution to clean the window's internal data structures or show me how to open the port?

• How can I create a USB Virtual COM Port

  Windows XP Professional / SP3 / 2002 Version

  How do I create a virtual COM Port to USB, so I can run software applications of a Bus USB flash Drive?
  The reason why I am eager to do it, is because I use an audio sequencer and it requires 1 GB of free disk space and at least 1 GB of RAM is recommended. My machine has 0.5 GB of RAM and a total of 6.55 GB of FREE space. My machine has a 256 MB RAM module and I bought another 256 MB RAM module. The manufacturer said that 512 MB of RAM is the maximum that can have my camera.
  My goal is to buy a 4 GB Flash drive and use it to add RAM on my machine. I am also wanting to be able to run software applications that are installed in the USB Flash drive.
  My basic goal is to install the DAW in the USB Flash drive and work with the program that is in the USB Flash drive, and I hope that will release of enough memory on my laptop.

  Hello

  Unfortunately, you cannot use a USB flash as a substitute for the RAM drive.

• Access to the BlackBerry through the USB port on the virtual machine VMWare

  I have my development environment configuration in VMWare virtual machine, and I have no problems of deployment of BlackBerry applications on a simulator that runs as another virtual machine. The problem starts when I try deploying to the device via the USB port. The address is assigned when the mode of development on the device is not accessible from the VM, but only from my host, who do me any good, since as I said my IDE is in the virtual machine. A way to solve this problem? I can still deploy to the device via wi - fi (which is btw access via different ip - one given by the network) by this can sometimes be slow depending on the strength of the signal, etc, so I prefer to be able to deploy via the USB port.

  Just in case anyone has the same problem, how to activate must, VMWare Player click on the USB icon (to the right) and choose to disconnect from the host. Connecting the USB port at the prompt. Stupid...

• How to access a host USB Virtual Serial Port from a VM Application?

  I have a Linux VM running under VMware Player 5.0.2 on a Linux host machine.   I have a development system running on the computer, virtual trying to download the code on an external device connected via a virtual serial port USB host (ttyACM0).   Anyone doing programming Arduino device will be familiar with my software/hardware config.  Dev VM system does not directly hear the ttyACM0 port I need to establish some sort of connection bridge between "ttyACM0" host port and the port of VM-configured "ttySx"?   Someone did something like this with a VM Player?

  FYI, I found the answer to my own question in an old post on a similar topic. Here's a response provided by the user 'Worker' in the former post office that was the solution to my problem.  I followed its general approach and mounted my own virtual *.vmx machine configuration file to change the serial port set of ' / dev/ttyS1 "to" / dev/ttyACM0 ' I can now download code on my device directly from the Arduino IDE running on the guest VM system.

  Worker (1 positions since November 23, 2010) November 23, 2010 12:56 am (in response to AnthonySowden)

  A bit of an old thread here, but I wanted to say that I was able to do exactly this yesterday using VMware Server 2.

  It wasn't easy, but I managed to hack in there.  I guess that this trick works also on VM WS but I have not yet tested.

  Here are the steps:

  Start your VM turned off.

  Add a serial port of your virtual machine through the normal interface. -J' I just let it use/dev/ttyS0.

  Go to your virtual machine folder and edit the .vmx config file.

  Find the line:

  Serial0.filename = ' / dev/ttyS0 ".

  Replace:

  Serial0.filename = "/ dev/ttyUSB0 '.

  and off you go.  The guest operating system sees it as a real physical serial port and is fortunately out my system through series console!

  Hope that helps other people.

• enable the USB ports from a Mac to a virtual machine view

  I use a Mac with os x 10.6.8 and spin the view client 4.5. When I connect to my computer via RDP virtual, I noticed that my USB ports are not flowing on to my VM correctly. I have test it with a USB key. See my Mac well USB key, but it is not viewable in my VM. I checked the settings of pool and they are configured to allow the USB transfer. Is there something else I may be missing?

  Thank you

  Devin

  I found that a certain time at the time where I was doing a similar search.    Try and see if it works for you.

  1. Open the Applications folder on your Mac (or anywhere where you installed the VMware View Client).
  2. Click right (or Ctrl-click) on the VMware View Client app and select to view the contents of the Package on the shortcut menu.
  3. Finder will now show you the content of the application. In this new window open the content of the folder, and then open the resources folder.
  4. In the folder resources , you will see a file named vmware - view.rdp. This is the model that the View Client uses to generate new RDP connections. By changing this file, you can change the behavior of the RDP sessions that creates the view.
  5. Open the file vmware - view.rdp in a text editor and change the entry for DriveRedirectionMode, changing its value between 0 and 1.
  6. Save the changes, you will be probably prompted for authentication of your Mac (because you modify the content of an application in the Applications folder).

  The next time you start the client VMware View on your Mac, your local hard drives will be available inside VMware View. You will see a security warning to each connection on your Mac drive for potential users of Windows sharing. Also note that any connected USB drives need to be connected to your Mac before launching VMware View for them to be visible.

• USB/Virtual COM port Communication problem with ESP301/LabWindows/CVI

  Hi all

  I have gone through different threads posted in this forum for similar issues and all tried, but nothing helped.

  I'm trying to communicate to the ESP 301 training monitor via a USB port configured as a serial COM port using a CR. Have it ' command is to get the version of the controller. The "write" "ComWrt" command works fine but the read command throws and error ("-99 operation e/s timed out"). I tried all the suggessions; with delays etc... who has explained (resolved by Mr. RobertoBozzolo) in the thread posted here, which explains an issue similar to that of the mine, but the help couln t.

  return the situation;

  }

  Can anyone suggest where I am doing wrong?

  Thanking you in advance.

  Another thing you should check is baud rate.  The ESP301 by USB is expected than the baud rate to 921600.  The function for OpenComConfig() group implies that it does not support this baud rate setting, but it seems to work perfectly.

• virtual serial port

  I have a portable satellite wih only USB ports, now I have a GPS18USB but the Route66 programm wil only work with a gps series. I have now that it is possible to create a virtual serial port that can help me and tell me how
  email please at [email protected]

  Hello Hans,.

  I had searched the internet on installation of a virtual COM port, but I only find solutions based manufacturer. So I think that the driver or the software that generates the virtual COM port is based on the product that you (in your case, the gps system).

  The manufacuring company request a solution!

  But if they don't have a solution, I found a link on the internet that might help you! But if you want to test I will assume no responsibility for the consequences such as loss of data after a system crash.

• Assignment of a USB port to a COM Port.

  I am running Windows XP Professional I have software that uses COM ports in the settings.  You can use my USB devices.  My computer only has USB ports. How can I redirect say COM 5 to a USB port or a device?  Can I connect a USB device to a specific COM port?  I know that if I use a USB series adapter it gives me a virtual com port is it possible to assign USB to a virtual com port without the adapter?

  As I pointed to a poster earlier in this thread, there is no way to make a USB port to simulate a COM port in the software.  Necessary pins simply do not exist.  You need a USB adaptor to series which is located practically in the world of computers and their accessories are sold.

• Can I attach a hub to the USB Port on E1550

  I would like to attach a USB and a DVD to my E1550 is it possible?

  @Neil_H

  We audited by our second level support team and it "s not advisable to connect a USB hub to the USB port on the router. The E1550 USB port is used to connect a device to external storage only, not even for virtual USB printing. It supports file sharing at home or on the Internet.

  Links of USB storage on routers Linksys support FAT32 and NTFS with HFS for newer models. You can check this link for the manual of the device.

• Can I connect printer to the usb port on the cable Modem CM100

  Hello

  This may seem like a stupid question, but here goes... I know that the usb port on my Linksys Cisco CM100 cable modem is an optional way to connect the modem to the computer. I wonder if I can use the usb port to connect my HP 1020 laser printer instead.

  The printer is not a network printer, and so I know that it may not work, but I have seen a few cases where a virtual port and install it as a local printer got to work.

  If I can connect the printer to the modem, and then he would give me a way to print from my laptop in the other room.  My printer is just beside my modem configuration and the router. I have a Linksys router WGR614 wireless who sees the devices on my network share, so I think he could see the printer connected to the modem (?)

  I couldn't find the answer to this anywhere. I didn't damage my equipment by blindly try this without knowing a little something. (I assume that the heart of my question is, on the CM100 usb port can be used for any usb device)?

  (I have Windows 7 64-bit operating system, in case you need to know).

  Thanks to anyone who can answer.

  A standard print server will allow you to connect a USB printer to your network. There are models wired and wireless depending on how you want to connect to the network.
