[SOLVED] usb port

hello, i need help again

I have a problem with the usb port, let me plug the modem on port 1 and then install the application, everything runs smoothly. but if my modem is moved to another port, the modem was not legible.

one more problem in the audio, if you raise the volume at the max, the program will be halted for a moment. there is a problem?

oops I almost forgot, why loading the login and logout windows are always long. sometimes force restart menu appears.

thank you for your help

im sorry, wrong room.
please move to the right place
