Hello experts,
I am facing a silly problem with the USB port and would much appreciate any help related to the issue.
Although I have downloaded the FTDI drivers from
http://www.ftdichip.com/Drivers/D2XX.htmand followed the instructions on
http://www.ftdichip.com/Support/Documents/AppNotes/AN_119_FTDI_Drivers_Installation_Guide_for_Windows7.pdfI still can't upload any sketches as the computer thinks the serial port is already used.
The serial port is recognized as USB Port4 but never recognized the device's name id.
The following message shows up when trying to upload the sketch:
Binary sketch size: 4,824 bytes (of a 258,048 byte maximum)
processing.app.SerialException: Serial port 'COM4' already in use. Try quiting any programs that may be using it.

I am using an Arduino Mega 2560, not that changes anything, but might be helpful to know
Any ideas what to do?
Thank you very much for reading
