Anyway to bypass a broken USB port? I got an error saying that my USB device was drawing too much power and had to shut off.

Question

I have a macbook pro. I just upgraded to Mavericks last night hoping this would fix the problem, but it hasn't. I received this error message and now none of my USB ports are working. I researched some and people have told me to reset the nvram, yet it is still not working. I have seen Thunderport docks that include USB ports on them, but they cost around $200. Just seeing if there is some sort of adapter or clever way to get around this problem? I mainly use my USB port for a Wacom Tablet. I was thinking about replacing the logic board, but that would be my last option. also, when i plug my phone into one of the USB ports, it shows that it is charging my phone, but it doesnt show up on my computer.
thank you!

You may see if you can get a rise out of it by use of another reset...

Generally when combined total of items plugged into USB bus, where
ports are powered from one internal source, is too high, you'd get &
use a USB powered hub. This has a power adapter, so the USB bus
in computer does not need to try & support more load than it can.
Avoid charging an iPhone, iPad, etc from the computer, those little
USB chargers are better. And the Wacom tablet may be OK when
the computer is running on the power adapter.
The computer may not need a new logic board, but an adequate diagnosis
should be done before any major efforts are made into a big takeapart.
If you are in the USA or Canada, an Apple Store with Genius bar could
help determine the issues in the portable computer, if you check ahead &
set an appointment to discuss and diagnose this issue. This should be free
however the repair of any issue is another matter, and would cost. You can
take the unit anywhere qualified certified authorized trained Apple specialists
hang out, for further testing and repair. Or trust a reputable repair company
at a distance, and mail the computer away, after contacting them for details
on how they prefer to set up the repair, and how they want it shipped.
If you do get it repaired for one thing, while it is open consider items such as
a new larger capacity hard disk drive, etc. Otherwise a little while later, it may
be due for one, as they will fail. Even the fancy SSDs can fail quick enough.
Hopefully you can get USB to work good enough to further troubleshoot.
Good luck & happy computing!
