Urgent USB problem

I just purchased a Satellite C55-B200 exactly 2 weeks ago today, and I was told that I have exactly 15 days that I can bring it back and get it switched out if need be, so I've got to make a move no later than tomorrow if needed.
I am completely pleased with my computer and would gladly take a trade if necessary.
My problem is simple: 2 out of the 3 USB ports on it don't seem to be functioning right. The reason why I didn't notice earlier is pretty simple: For one of them (the only one on my left when facing my screen), I always had the mouse plugged in, and haven't been gaming or anything like that on it so I didn't notice anything was wrong with it, and I never kept anything in one of the USB ports on my right side.
What happens is pretty straight forward. Anytime I put any USB device in the USB plug on the right side of my computer I get a message saying that it wasn't recognized, and can't open it. However, if I put the same drive in either the USB 3.0 plug or the plug on my left it works just fine (the USB 3.0 plug works indefinitely, the one on my left has some problems). On my left, I just began hooking up hard drives, and I've noticed that no matter what I do the drive seems to disconnect and reconnect for no reason whatsoever. When I just had a mouse in it I think I was chalking it up to just a little cheap mouse glitch (was using my portable mouse on it). But that's not the case.
Every single one of my hard drives not only work completely fine, but I can plug them into the USB 3.0 drive and run them with no issue. That goes for both flash drives and external hard drives (only one of which is actually a usb 3.0 device). But, when put into the other plugs, they always malfunction (non-workable the 2.0 plug on my right, and constant random disconnects the usb clum on my left).
This is a major problem for me, because I've got a large library of things I was planning on moving using this computer, but if only 1 USB port reliably works I'm in trouble.
This computer is pretty new (2 weeks old), and has only done one major update. I'm not sure if this could be a software glitch or if it could be a hardware glitch.
If it is a hardware glitch (or more than likely is) I need to get it changed out now later than tomorrow. I don't like making a fuss over things like this, but typically I use at least 3 USB inputs on average (counting the mouse), so having a malfunctioning computer that can only use 1 inpute reliably really messes me up. I don't know if it might be some kind of software thing or a hardware problem.
Thank you guys for any assistance!
EDIT: Just for clarification, I bought it from Best Buy.

I would give it back to Best Buy for one that works! You shouldn't have to "fix" a new computer,particularly with problems that will probably turn out to be hardware related.

USB problems since EFI firmware update 2.6

My MBA has been suffering USB problems since this update.
I have an IOGear USB 3 GUH374 hub. I connect my iPad mini and USB 3 disk to it.
Since the update, the iPad has stopped charging through the hub. Now, I can't find the power specs of the hub, so I don't know that it should work, but it was working fine. Now, the iPad says "not charging".
The USB disk has spontaneously disconnected a few times, with the system reporting that it was improperly disconnected. One time, the disk was corrupted.
This could be a coincidence, so I've contacted IOGear. But, I'm also having new, different, sleep problems with the MBA and Mountain Lion.

MAC PRO USB Problem - Traced to bad Apple Keyboard Extension Cable

I found a fix to a problem synching to my itunes Library on my early 2008 MAC PRO. The Apple supplied USB extension cable for the keyboard was defective.
The symptoms were hangs in itunes and finder synching to iPods and transferring data to USB hard drives. The iPods and hard drives never lost power and no errors/log entries were made. The transfers simply stalled and would not continue. itunes and finder would hang until the drive or ipod was removed. These devices were installed directly to USB ports on the MAC PRO. No other USB devices were connected except for the aluminum keyboard and mighty mouse; the mouse was connected to the keyboard. The keyboard was connected using the USB extension cable that shipped with the MAC PRO.
Hardware diagnostics were all clear. The keyboard and mouse never had any connection problems. Only itunes syncs and hard drive copies would fail; these would occur at random times. I had an open ticket with Apple to have the logic board replaced as it was diagnosed to be a hardware/USB problem.
Removal or replacement of the extension cable on the keyboard (which was connected to a different USB port and NOT in the USB chain with the ipod and hard drives) permanently fixed the problem. I cancelled the Apple HW replacement.
I have noted several posts with others having problems with USB ports and devices. I wonder if Apple has an unknown problem with bad keyboard extension cables.

I think you may be onto something there. I'm just a few weeks into my second Mac Pro and again it's having the same USB problems which led Apple to give me a replacement machine previously. I went through several weeks of considerable testing with Apple Engineers prior to that - an Apple Care application to collect data from my machine, Apple Developer USB prober and two clean installs. The latest machine initially showed no sign of the problem then it started again - 2 iPods "can not be read or written to" part way through sync, Aperture quitting importing from USB SD card reader, USB drives dismounting etc. So I pulled out the Aluminium keyboard and, lo and behold, the iPods managed to get all the way through synching without errors. I really like the alu keyboard so it's a huge shame that it might be the cause of all my problems so far - and the Mac Pro is otherwise a beautiful computer.
But is this really a hardware problem of the internal USB cards and power management or supply?

MS-6390: Return Of The USB Problem!

Almost a year ago I posted a thread regarding a USB problem in which after a few hours runtime, the USB ports stop working. Having reinstalled Windows, I followed the original thread to fix the problem again but this time, it hasn't work. The old thread for reference is; https://forum-en.msi.com/index.php?topic=49727.0
but I shall try and include everything important here so it shouldn't be needed.
Firstly the nature of the problem;
Any new device plugged into them is not recognisied and Windows advises that it is the device that is malfunctioning.
Restarting the computer will eliminate the problem, however upon rebooting, the computer tends to get stuck at what may be the memory count. If left for 10 minutes, the memory amount comes up and the computer boots normally. This is circumvented by temporarily (one second) removing power to the power supply by pulling the plug or flicking the switch at the back.
[It may or may not be relevant that the HDD activity indicator is lit for approximately 30 seconds of this 10 minute period]
Upon switching the computer on again, the computer boots up normally and the USB ports continue to function for another variable period of time.
This problem occurs if there are no devices plugged into the USB, any single device (printer, gamepad, mobile phone) or any combination.
It should also be noted that if the computer crashes due to any of many unrelated reasons after this problem has arisen, and I use the reset button to make it reboot, the 10 minute reboot problem occurs again but appears differently on screen in that it actually says 'memory check' or words to that effect with a space where the normally RAM amount goes, a '+' and another empty space where the memory reserved for onboard graphics normally goes (i.e. memory check: + )
I've tried uninstalling the drivers and reinstalling those downloaded from VIAs website for my chipset.
My USB ports are set not to power down to save power in device manager.
The multi-card reader (plugged directly into the motherboard) also stops functioning when the USB ports go down - power light stays on, activity light stops flashing (occasionally power light turns off). Unplugging it from the motherboard does not resolve the issue.
I want to resolve this issue so the computer is trouble-free when I give it my mum to learn from.
Comp. specs in signature. Thanks in advance.

I don't know how to dig deeper... Soon this computer will only be using a single 80 gig HD, and I'll remove the fan controller (it'll be mums computer). I'll then be able to try just using sp1a.
This PSU I'm using is reviewed here with a several others. (the model number is the same, but the one tested doesn't appear to be dual rail - they actually state the number slightly incorrectly, but it's correct in the picture of the label they show.
I think it performed quite well, being one of only two that were able to keep producing (just) over 1 v at 100% load, whilst most others just plumetted. A significant but probably not damaging drop to 4.87v on the 5v rail and again 3.26 on the 3.3v rail all at 100% load (which you're never supposed to due to the PSU anyway). It got a recommended award since apparently it doesn't have many features but I don't think I'm in need of any features it lacks.
Furthermore - at the back it has a control for fan speed. Currently set on Auto, it maintains the same fan speeds (audiability) as on Low - thus I conclude it has headroom to push itself if necessary (in which case the fans would spin faster).
Apart from someone who said they're "cheapo", I havn't yet found any negative comments regarding Jeantech PSUs.

Shuffle USB Problem - Some Observations

I decided to start a new thread with some additional observations I have made regarding the Shuffle and USB problems. Some of this already appeared as a reply to the "ipod usb" thread. Anyway recapping from my previous post:
When plugged into the USB port of my machine, the front LEDs (above the control area) flash the following:
GREEN and ORANGE (YELLOW?) flash together for between 1/4 and 1/2 second. This is followed by the GREEN LED alone for about 1.5 seconds. 3 seconds of nothing, then it repeats. The battery condition LED on the back (below the ON/OFF switch blinks ORANGE for about 1/4 second every 4 seconds.
Plugging the Shuffle into another computer (a laptop), the Shuffle is recognized and the LEDs behave normally.
Now the weird thing is that the Shuffle had worked on the machine where it is now not recognized. In fact the iTunes 7.0.1 diagnostics show the serial number of the Shuffle as the last iPod connected. Also, the USB on the iTunes machine is a USB 1.0 and on the laptop is USB 2.0.
NEW OBSERVATIONS:
My 20GB Click Wheel iPod works fine under 7.0.1. The fact that it works leads me to believe the USB port and power are fine. If it the USB port can drive a hard disk iPod, it better be able to drive a Shuffle!
I loaded up the version of iTunes that came with the Shuffle on another Windows 2000 box I have. The Shuffle was recognized and did a RESTORE on it. Windows even recognized it. The version of Windows IS NOT as currently patched as the computer on which I have iTunes 7.0.1 installed.
I uninstalled iTunes 7.0.1 and installed version 6.0. Aside from 6.o not starting because some file got converted, Win2000 still did not recognize the Shuffle.
So here are my thoughts:
1) A recent Windows 2000 patch causes Shuffles to be ignored by the OS. There is a comment about a problem like this with XP, but I was not able to find anything Win2000 related. The machine I am having problems with is up to dat with regard to patches.
2) If V7.0.01 is the problem, even uninstalling it and reinstalling an old version of iTunes leaves some part of the driver or something that still causes problems.
3) The Phillips Pronto remote software I installed somehow causes a bad interaction with only the Shuffle. Remember, my click wheel iPod still works!
Right now I am leaning towards an issue specific to Windows2000 and the Shuffle. Maybe a conspiracy to get us all to buy Zunes?
If anyone has additional observations or suggestions on how to fix the problem, I (and a bunch of other people) would really like to hear from you.
Thanks!
Don

Okay, I got focused on the fact that other machines
would recognize my Shuffle, but not my main machine.
It dawned on me that the Windows Registry stores
information about USB devices whether or not they
are plugged in, so I snooped around and found the
entries for the iPod.
I did some searches and found a reference to this MS
KB article:
http://support.microsoft.com/kb/315539/en-us
Basically describes how to show the "hidden" (i.e.
removed USB) devices. Went into the USB section and
deleted the 2 entries I had for iPods (my Shuffle and
20GB click wheel).
Plugged my Shuffle in and BINGO! Windows recognized
the Shuffle and iTunes 7.0.1 recognized the Shuffle!
In fact, as I write this post, my poor little
Shuffle is having my jogging play list reinstalled
since it got wacked by the 'restore' on the other
machine.
Bottom line, it looks like I managed to solve my
green and orange LEDs of death problem!
Your mileage may vary!
Good luck!
Don
Yes, great, this is a fix for this problem. Thank you very much.

Macbook Air 2011 USB Problem

Hi, I recently bought a Toshiba portable hard drive that uses usb 3.0. For some reason, my mid-2011 macbook air 13" is unable to connect to the drive with the USB3 to microUSB3 cable. However, the hard drive worked on a late 2010 macbook air 11", other macbooks and pcs using the usb3 cable. The Toshiba portable hard drive did work with my 2011 air with my friend's USB2 to microUSB2 cable so I decided to buy one on Amazon. Unfortunately, the cable that I bought from amazon did not work with my macbook air but it did work with my other pc.
My question is: Does my macbook air have a usb problem and should I go to apple store to get it fixed?
Thanks!

There have been more than a few threads on this subject of the USB 3.0 Toshiba Canvio problems. Here is an ongoing rather current discussion of the issue.

L505D-LS5001 no audio / no usb problem

i been having problems with my audio and usb drive, allready try installing drivers and nothing..
the audio tells me no audio output installed.
and the usb and sd card slot wont work eider. runnning windows 7 32bit , audio driver is microsoft audio highdefiniton with the yellow (!)
when i try to install laptops drivers go to the best drivers allready install.
usb problem i really dont know whats the problem..Laptop still on warranty.
Any help please

I have run into this same issue; it seems to occur that in device manager, no USB host is even present. Audio just has a red "X" on it.
I've tried installing the drivers, updates.
I restored from the Restore discs from Toshiba (which just crash)
I've done an install from a straight WIn7 X64 disc (which works, but then Red "X")
I've tried changing memory, HDD..
I've tried bootable LInux, which also doesn't see a USB controller.
This is very annoying. This seems to have happened after someone flashed the 1.10 BIOS onto this (I have an L505D-LS5007)
Something here is very amiss, and a laptop with no USB, no Audio is almost worthless. It's as though the BIOS control for the southbridge is wrong. I've tried re-flashing with 1.10, no difference.. I'd love to be able to rollback to 1.00, but I can't even find it.

K8T800 USB Problem

Hi,
First time poster!
I have a problem which I would be grateful for some advice on. Maybe the solution is for me to update the bios but thought I should check first.....
Basically when I connect my ipod to the front USB port and restart my machine, the computer will not get past the initial load screen (with the graphic on-screen). If I remove the USB plug then it continues to boot, but nothing happens unless I remove the plug!
Is this normal?? Please help!!
Thanks

Unfortunately u have the same problem i did. Although for me it was any usb device or even some PS/2 mice.
The solution is to spend 7 GBP on a PCI to USB card.
like this one (just an example, have a look around):

that fixed all my USB problems, which i couldnt fix any other way, and damn i tried!
good luck

Garageband opens now -- but USB problem

Applemeisters-- I just posted a note about how my Garageband won't open. Googled and found the problem. You must have the correct date operating on your computer or it won't work. I live in the Chicago burbs and, as a result of having power out for several days, the date on my computer system was off by that number of days. Corected that and Garageband is live again.
Now, about the USB problem. Please help. An Ion turntable that works fine with the regular stereo console, But when I plug it directly into my G4 tower with an OS 10.2.8 system and record lps into the audacity software the sound sounds miserable on the speakers while recording and miserable after I transfer the recording into a MP3. Is Ion supposed to be a plug and play for Apple or does it just work for PCs? What's a guy to do? Help. Thanks.
Paul

This is only a guess, because I've not got HK USB speakers: But maybe the master volume in GB is up too high. Take it right down and then turn up your speakers, see if that does it.
