On AMD platforms, setting of USBDEBUG_DEFAULT_PORT=0 tries to scan
all physical ports one after other in incrementing order. To avoid
possible problems with other USB devices, one can select the port
number here and bypass the scan.
Intel platforms can communicate with usbdebug dongle on one
physical port only, and this option makes no difference there.
