It is not clear what you mean by port problem.
Put a known good device in that port...process of elimination!
You will usually get an error during POST if there is a problem with a serial port.
it means your port for vuze is not open
One of the simplest ways is to use USB flesh drive, keyboard or mouse. Just connect to the port in question and try to use the device. If it works then the port is OK, otherwise you have found the port (or one of them) causing the problem.
Usually, because a serial port doesn't have to deal with the problem of signal skew that can jumble the data on a parallel port and gets worse proportional to distance.
If the port can fit it, it is ok. I tried it before, no problem.
No controller in port mean your controller is either defective, or broken. You will require to replace the device in order to solve this problem.
The problem is that the oil port holes in the heads are to small. This has been a problem straight from the factory. The best way to correct the problem is to drill the port holes bigger, but to do so this means the heads need to be romoved from the engine. It will take a good deal of time but it will help greatly.
If the unit is not responding to controller inputs try changing the port that the controller is in. If this does not resolve the problem try using a different controller. If no port appears to work and the controller is known to be working then the issue is internal. The most likely problem will be a loose or faulty controller port PCB.
No. If the device is not detected, you have a hardware problem, not a software problem. Something is wrong with either your USB port or your drive; uninstalling and reinstalling the software will have no effect.
Check the connections from the usb slot to your motherboard, could be a faulty port or a faulty motherboard connection
