Can I attach a HDMI cable into a USB port?
What exactly are you trying to do? A HDMI cable will not directly fit into a USB port. If you force it you will bust the usb port, and probably wreak the plug on the HDMI cable. You may also seriously damage any equipment connected to the hdmi cable or whatever the device is that has the usb port in it. HDMI is designed to carry video and audio, where as USB carers a single data stream and power. You may be able to get adaptors, or usb based video cards with hdmi connectors on them, but i don’t know much about them.
