Macbook Pro No Usb Port

I have been searching different threads since yesterday and figured why not start my own. I have a Macbook Pro 10.5.3 2.16 GHz with 2GB 667 MHz DDR2 SDRAM. The problem that I am having is that neither of the 2 usb ports nor the 400 firewire port is recognizing any of my external hard drives. I recently bought a 320 GB Verbatim Firewire/USB Drive and it is not mounting or showing up in the System Profiler, Disk Utility, or Drive Genius. It is formatted for Mac and works fine on my other Mackbook. I am having the same problem with other external drives on my Macbook Pro and I have tried using different cables. All of my drives do not use external power; they are powered via USB or Firewire. The lights on the drives are coming on when plugged in but the disk never mounts anywhere. Thank you guys in advance for any help. It is much appreciated.

If the USB ports not working on your MacBook Pro or iMac is a recent issue and there doesn't seem to be any problem with USB devices, it could be that an app is conflicting with USB functionality. If you've downloaded an app from an unknown source there is the potential for it to contain malware, which could also be the cause of the problem. I created a Yosemite boot USB, from the App Store version 10.10.1. Microsoft for apple imac. When I hold option during Boot, the USB drive doesn't show up on the menu. I have an aluminium MBP, bought in 2009. It is the full body aluminium with the Superdrive. Per Apple, this is my machine: MacBook Pro (13-inch, Mid 2009).

Another reason for your Mac not recognizing external drives is a dirty or loose connection between your cable, USB-C multi-adapter, Thunderbolt 3, or other connecting ports. Lucky queen slots. So check your cable, your dongle (if used), any additional adapters, and the ports on both computers and drive to ensure that they are clear, clean, snug and fit tightly to. The machine will start to boot from the USB drive. Way 2: Set a Mac Boot from USB Drive using Startup Disk. When you use Startup Disk preferences to set Mac boot from an external drive, so it'll boot from that disk until you choose a different one. Here is how: Step 1: Go to Apple menu System Preference, then click Startup Disk.
