wow...have you installed new drivers?  new hardware?\n\ndid you check the system - hardware under control panel?  is the port ok or is it x'ed out?  unknown hardware?\n\nif all the above is ok, I would delete the device and reboot and see if it reinstalls ok...

have you called their support number (1-877-722-3755)? for intermittent connection --- there might be some problem with the line. have you asked them to have a line check? there are some process or troubleshooting they could give you to have it fixed... and it should be the line dept. who needs to check it for you. its not only on SBC server but also they need to check on your area, where there might be some circuit problem.

The easiest way to get started with serial port communication in LabVIEW is to example program.  If you are using LabVIEW 7, click on "Find Examples..." under the Help menu.  Under the folder "Hardware Input and Output" there is a sub-folder called "Serial".  Open the "Basic Serial Write and Read.vi"  Set the proper COM port settings with the inputs on the left hand side.  Use the toggle switchs to select the READ or WRITE function.  Run the VI.  Once you get comfortable using this VI manually, you can call it as a subroutine in your own applications.

Hey Pal,\n\nI think that you should use Serial Port witn a serial cable and use the hyperterminal program to config your reciever.\n\nCiao,

you need a null modem cable.\n\n\nlike a parralell to parralell or serial to serial  then use the direct cable connection tool to connect.\n\nMust be running on both machines.. one running as host one running as client.\n\n\nhope that helps

Check your device manager to see if its listed under "mice and other pointing devices".  It should say something like, "Synaptics PS/2 Port TouchPad" or something similiar.  If you don't see it there, RIGHT click and scan for hardware changes.  You may need to perform a system recovery.  Otherwise, go to Best Buy and get a wireless USB mouse.  It's what I use for my laptop, works great.

Or uninstall it, play a bit with the registry (which could mess up your pc if you're not familiar with that) and reinstall it. You could also buy it or get a serial number from somewhere.

Try reinstalling the driver or check with the manufactors web site for a updated driver or one that is wrote for your Operating System.

your ethernet port may be bad or maybe you need to reinstall your network drivers

to check the com port use a serial mouse on the com port if it works then your com port is working proparly & there is problem with your cdma cable

Check the power supply cable (the one with the 4 pins).  It sounds like it just isn't getting any power.  Even if there's something wrong with the jumper settings or the I/O interface, it should at least spin up.

You could have a short in your USB port.  Try putting other devices in the same port and see if the problem persists.

I think you may have the problem with your USB port. Just plug the device in other USB port. If you get the same message just go to the(Assuming that you have installed win XP) \nMy Computer>>Properties>>Device Manager>>Universal Serial Bus Controller(Select it) and uninstall all the ports and reinstall. \nIn win98 My Computer>>Hardware>>Device Manager.\nSame procedure.\n\n         Just see what happens.

the probabilities\n1) your mouse needs repair\n2) the cable problem\n3) the sensors are dirty (Just open the mouse from the bottom see if the sensor's have accumulated dust you can clean it with smoother things)\n4) there are viruses which simply makes the mouse non functioning\n5) check the port\n6) is nothing works just throw the it away and buy a new one its cheaper.\ngood luck
