One USB Port not Working Properly on MacBook Pro 3,1

Question

I have an older macbook 3,1 running Mavericks OS and recently one of my left USB ports has not been:
1) able to eject external hard drives plugged into it (I have to force eject)-instead it gives me a message that one or more programs may be using it (even though I don't have any programs using it).  The hard drive is being powered by USB has a 3.0 connection although this wasn't a problem in the past... I tried the other USB port and it can eject just fine from that port.
2)Intermittent communication with mouse.
Not sure if this is a hardware issue but when I try to run diagnostics on this laptop by holding down the "D" key at startup it doesn't take me to diagnostics. I no longer have the discs for this laptop (containing said hardware test) so I can't boot the diagnostics from that discs. In lieu of a hardware test I opened CONSOLE and did a search for USB and there were a couple of these messages:
8/29/14 12:13:43.000 AM kernel[0]: **** [IOBluetoothHostControllerUSBTransport][SuspendDevice] -- Suspend -- suspendDeviceCallResult = 0x0000 (kIOReturnSuccess) -- 0xdc00 ****
Is this a logic board issue? Would rolling my OS back to pre-Mavericks work? The problem didn't emerge right when I updated to Mavericks however I have had luck changing OS stuff (updating or rolling back) with faulty USBs...
Here are other troubleshooting methods I have attempted with no success:
-Disk Utlity (repair disk and permissions)
-RESET PRAM NVRAM
-Remove battery
-RESET SMC
-Shut Down
-Run Disk Utility @ startup
I'd love to get access to a Hardware Test compatible with my macbook. The links I have found online are to incomplete files. If someone @ Apple could send some Hardware diagnostics tool my way via a disk image that would be perfect.

Answer 1

Did you boot into Recovery or try & run OS X Utilities, to attempt a test?
Depending on the computer, that may be your best bet, short of taking
the computer to an Apple Store with Genius bar; or to an AASP who is
trained in Apple repair & testing services.
A replacement of original install restore DVD with the correct AHT on
a bootable DVD, could be obtained by contacting Apple support or
the main online Apple sales, or applecare; there would be a fee.
They'd need to know the Serial Number and product info, and you'd
have to provide a form of payment in order to get replacement discs;
and if the computer is way too old, those may be harder to get now.
The main system tools could be installed in Recovery partition.
And Ms Sammit may have answered this.
Good luck & happy computing!
