How to re enable usb device

i plugged my western digital hard drive in a docking station to access the drive.
it starts up makes all the noises a booting drive is making but then it doesnt appear on my desktop nor in my disk utilities. i plugged in another hard driveand i had the same result. i plugged it into my 10 year old pc with windows xp fisrt version and it worked!!!!!!!!!.
i had access and could read and write onto the drive.
when i pull the usb cable out in the corner the message appears
i'm running maverick on a early 2008 MBP
please help
thanks

What happens when you connect it directly to the MBP? Try all USB ports.
Ciao.

On my MacBook Pro with Retina Display, Why does the "USB Devices Disabled Unplug the device using too much power to re-enable USB devices" keep coming up after I unplugged the usb device?

On my MacBook Pro with Retina Display 15", that I purchased a few weeks ago, started coming up with the following message on my desktop:
"USB Devices Disabled Unplug the device using too much power to re-enable USB devices".
I unplugged the device and the message still keeps coming up.
This is what I have done so far to troubleshoot:
I shut down the laptop. When booting up I pressed the command+option+p+r at the same time. It comes up with a menu to reinstall OSX, Get help online, Run Disk Utility, etc. I choose the disk utility and repair the disk and then restarted.
The message keeps popping up and I can't seem to get rid of it. Why does the message keep popping up even though I don't have any devices hooked up to the laptop at all? Any help to reenable my usb ports and get rid of the messaage would be helpful.

I talked to Apple Support and we at least stopped the bleeding, a little bit. These are the troubleshooting steps I did before I contacted Apple Support:
1. Reinstalled OSX
2. Restore the last known good Time Machine Backup.
This did not fix my issue, so I called Apple Support and they told me this:
1. Turn Power off.
2. Wait 15 seconds.
3. Plug in Magsafe adapter.
4. Wait 15 seconds.
5. Hold down the Shift+Option+Power Button for 20-30 seconds.
6. Turn Power back on.
Ok, this stopped the bleeding a little, but as soon as I plugged in a Apple USB Superdrive
and a Apple Mini Displayport to VGA Adapter. This "USB Devices Disabled" pop-up pops up like every 30 minutes now. At least, it is not constantly popping up after I close it, so I guess it will do for the temporary. Going to contact Apple support, later, though to see what else can be done.

Hey HoustonSmith, using to much power generally means a short. Do not use this cable, the lighting cables have a history of failure; shorting out. If within one year of purchase date take it to Apple, the cable also has a one year warranty, if short is do to manufacturing flaw and not abuse Apple will replace it free! Otherwise a new cable is around $30. You could also try a reset or restore, but don't think a glitch is your problem. If you do try to restore, just remember to make backup copies of all the info / data on this iPod to your computer first, then attempt to restore. Good luck. Cheers.

How to stop/disconnect USB device on OSX?

How do I manually stop a USB device that I don't want the OS to recognize or run?
On "About this Mac > More info" page, my Dell Axim X51v Pocket PC is listed as a USB device. I'm having problems using the Parallel Desktop running Windows XP to sync to the Axim because Parallel reports that "USB device you are trying to connect to the virtual machine is being sed by another process." Wait 5-10 seconds, then try to connect the device again. If this does not help, find the application that blocked up the device and disconnect it manually."
AFAIK, nothing on my Mac is using the Axim right now, I have even disabled "Missing sync for Windows Mobile" and stopped it from loading so it must be the Mac OS not releasing the USB link so my Windows XP within Parallel is not able to pick up the Axim right now.
In Windows, there's a "Remove Hardware" option. But I can't find this on OSX after digging around for half an hour, I think I'll get much better advice here, so I really look forward to your help.

You wrote: "But I don't see the device as "mounted" on the desktop, or in Finder."1. In the Finder > Preferences > General tab, is the "Show on Desktop" option for CDs, DVDs, and iPods selected? If not, select that option and see if it appears on the desktop.
2. Is it shown in the Finder Siderbar?
Good luck!

How to blacklist a usb device in BSD?

I am having trouble communicating with a usb device while running Virtualbox on my iMac (Lion). Virtualbox is virtualization software which lets me run Windows XP as a guest OS. I am trying to run Palm Desktop for Windows on the virtual computer and I have trouble getting the USB connected Palm device to sync to the Windows application. It turns out the Palm device's use of the USB protocol is not quite conventional and so the virtual OS has trouble capturing it and presenting it to the Windows application.
Others who run Virtualbox under linux have seen this same problem with Palm devices and have found a workaround by disabling the host linux USB driver so that the Virtualbox application has unfettered access to it. This process is called "blacklisting" a USB device under linux, and involves editing the "/etc/modprobe.d/blacklist.conf" linux config file. My question is can I perform a similar operation in MacOS? The BSD I/O subsystem is different enough from linux to prevent me from knowing where to go in OSX to do a similar modification.

I'm having the same problem. I can't get OS X to ignore an SPI digital logic device (MCP2210) that I want to run from my Windows XP Virtual Box in order to control an experiment. Virtual Box sees it but it's grayed out under the list of USB devices to mount in Windows XP, and I don't know how to get the Max OS X to released/unmount/ignore/blacklist it.

Try unplugging it. Give your iPad a reset by holding down the sleep and home keys for about 20 seconds (until it reboots) then try again.

Need information on how to comunicate with USB devices

I have an aquisition unit that connects to the computer trhough a USB port. Does anyone knows how to comunicate usb devices with labview using a Universal Serial Bus (USB)?

Sorry for digging up old threads, but it seemed most relevent, and I always figure it's best to add onto old then start new. For ease of the next persons search.
So anywho, My first question is... I assume it is not necessary to open and close VISA sessions to USB ports, right?
I am having an issue where my device doesn't like to work unless a specific series of events take place... very unlike USB Devices in my experience. For instance, if you have the said device plugged in, and you turn it on, then open labview. It will spit out garbage. If you close labview, do nothing else, and open labview up... it will spit out the same garbage. ( by garbage i mean a series of y's with dots over it, and odd looking p's ... you know the kind of letters you get by pressing alt+###... i think in hex it winds up spitting out something like FF EF FF FF FF EF EF ) .... now, if from this current state, I unplug the USB and plug it back into the device, it will finally start to communicate properly.
Im curious why either labview or the computer itself are not recognizing the device on the USB port properly unless it is unplugged and then plugged back in. Ive tried to do reading on USB, and got all sorts of interesting tid bits of somewhat useless information. Im trying to determine if this is something I am not doing in labview, or if this device should have a driver to register with windows, or what exactly the issue is... Just a little background, I do explicitly know all the individual commands to this device so it is not an issue to communicate with it directly through visa...
Thought some of you might have insight or some similar USB experiences....

Use a powered USB hub.

How to debug adding usb device

When I add my new Iomega Helium USB HD to my Macbook Pro running 10.6.8, the screen and keyboard all freeze. There laptop has to be rebooted. It does this when I do it standalone and when I use external screen, keyboard and hub.
It is a problem with my setup because the drive works fine will all of the other Windows and Mac machines I have.
The cause was the installation of the Iomega software (why did I ever trust Iomega software?) as I only installed it on my macbook pro.
Can I run some diagnostics/debug to trace the insertion of the USB device to see where it is going wrong? I have manually uninstalled the software but I am convinced I have missed something.
I have a complete clone backup from before the installation but don't want to lose other changes (like email etc) since that day, although I am happy to restore specific files.
Thanks

And it used to be fine until I installed the Iomega software.
Iomega software, i.e., software to use an external drive. Never a good thing (I guess you are finding that out).
I always recommened external enlosures which are dumb boxes, i.e., their only purpose in life is to allow you to communicate with the drive they enclose. Additional software only gets in the way and you shouldn't need it.
If that box was running fine without their software what prompted you to add it? And why can't you uninstall it?
