USB disconnects when plugged in (Solved)

Hey Guys
Just got a W510 and I love it. It has its quirks but this machine is really a beast. However, I noticed a strange problem. If I have my iphone connected to the powered USB in the back, and I plug in the charger the iphone starts disconnecting every 10-15 seconds. It (the iphone) becomes useless at that time. I have to unplug the power connector to get the iphone to stay connected for longer than 15 seconds. Anyone have any similar experiences? Any idea why this would happen?
Thanks
Update
Found the solution. In the BIOS there is a setting that lets you choose the profile of the device that you would be connecting to the powered USB 2.0 outlet. I had it set to automatic when I was encountering this issue. Changed it to ipod and now the problem is gone. I have some other devices that will be connecting to that port. If I see any problems with any of those, I will post here.

Start with these articles and see if that gets you anywhere...

Garmin Forerunner 210 keeps connecting/disconnection when plugged in HP Pavilion dv6-3040sd

I have a problem connecting my Garmin Forerunner 210 (GF210) to my HP Pavilion dv6-3040sd. I know the problem is with the laptop, because i tried several other laptops and on those it works well. When i connect the device, windows installs the drivers. so far so good. When the drivers are installed, the laptop recognises the GF210 and it connects. A window pops up letting me choose what i want to do, but before i can decide the device is disconnected and connected again. It goes on and on like this.
On onther laptops the GF210 is seen in the 'Computer' section as a external harddrive.
My laptop is running on Windows 7 64-bit and all the latest updates from windows are installed.
Does anybody know an answer to this problem?
This question was solved.

Hello again HarmR,
It is good to hear back from you!
Since you have already applied the document above with no success, I recommend changing the drive letter of the Garmin Forerunner 210. This can be done by following the steps of this document on how to Change, add, or remove a drive letter.
Additionally, I also suggest following the steps below in order to recognize a USB device in Windows 7:
Step 1. Click Start
Step 2. Click Control Panel
Step 3. Click Administration Tools
Step 4. Click on Computer Management
Step 5. Click on Disk Management
*** If it was not seen there, go to 'Action' on the menu bar, click on 'Rescan Disks' and it should come up. If it does show here does it have a drive letter assigned? If not follow the instructions below:
Step 1. Right-click on the removable drive
Step 2. Click on Change drive Letter...
Step 3. Assign a drive letter
Please re-post with the results of your troubleshooting, and I look forward to your reply!

Ipod only says "ok to disconnect" when plugged into mac

When I plug my 1st gen. 5g ipod into the Mac it only reads "ok to disconnect". I have tried on several Mascs with the same result. Diagnostics run on it and everything is fine. I can listen to music, just can't get the Mac to see it.

I'm having the same problem. I just installed Tiger and iTunes read my 1st generation iPod once or twice, but now won't recognise it at all. Help!

Buzz from USB microphones when plugged into power

My Macbook Pro causes a buzz to appear in video voiceovers when I use my USB headset while the Macbook Pro is plugged to power.
If I unplug the power adapter then there is no buzz.
I am quite concerned there is a short in the circuitry of the MBP as I have never had this problem on my old MP or on my MacPro.
Has anyone had any experience with this?

Hi Fastman: Sorry, maybe Duck Head is a local terminology for the plug part that is attached to the power adaptor. It may be set up differently in Australia. Our power adaptors in Canada, and I believe in the US as well, also include an extension cable with 3 contacts. The 3rd contact provides a ground.

Left USB Sparking when plugged in.

Hi there,
The left side USB on my PB has started sparking when I plug a usb cable in. It feels magnatized when it does, and at the exact same time my power plug turns off (ie the yellow or orange light turns off and the power stops working.). The USB then doesn't work and I have to wait about 10 minutes before putting the power back in and it starts working again.
The USB on the right side does not do it, and works fine.
Could someone please help me.
Regards.
Rhys Stephens

I don't know about the magnetized feel, but either one of the pins in the USB connector is bent up or there's something wrong with the board that the left USB connection sits on. Your best bet would be to have it looked at by your nearest Apple repair center (if it's under warranty)

Imediately disconnects when plugged into computer

When I plug the ipod in it brings up the connected screen on the ipod and brings up the syncing screen in itunes then immediately dissconnects. If I try to to apply changes, when I push apply it again says syncing in itunes but the ipod just remains on the menu screen and then a box pops up on itunes that says ipod could not be synced. the required disk could not be found. restore doesnt work either. i believe it generates error 1436 was the number. any help?

I had the same problem. The problem was my docking cord and my ipod's docking plugin. I took it to a appple store and they replaced my ipod. Good Luck!

Wireless Network disconnect when plugging or unplugging A/C power on T60

Wireless disconnects whenever I connect or disconnect the power supply (no matter what percentage of remaining battery).
ThinkPad T60
This issue is reproduceable and also happens on my coworker's T60 too.
Message Edited by perlphp on 12-13-2008 03:14 PM

I am told this can be caused by Deep Smart PowerDown enabled on the WIRED
connection, which causes the adaptor to vanish from the list in
Windows.
The wireless then disconnects, even though you're not using the wired adaptor!
To fix this:
1) Control Panel -> Network Connections
2) Locate the icon for your wired connection, right click, properties.
3) Click the configure button top right
4) In the advanced tab, scroll down the list until you find "deep
smart power down" (called something different on a T61) and change the
state to disabled.
5) Click OK twice.
This fixed my disconnection problem!

Software that syncs usb drive when plugged in?

I always use time machine to backup all my files in a large external hard drive. However, I have a file that I use to store information that I need to access and edit many times throughout the day both in my macbook pro and in my flashdrive on other computers. Is there some software for the mac that is available that can syncronize one file on the desktop of my macbook pro with the file on my flashdrive with the most recently edited one?
Something like SyncMate would work well, if it wasn't so expensive.
Please let me know if there is anything that could work.
Thanks

Possibly turn off the Auto Import facility. It is probably assuming there are images to import.
Also just in case you didn't know Vista support is unofficial at the moment :)

30 gig iPod not found in My Computer or iTunes when plugged in

I just got this iPod the other day for a birthday present from my father. I immediately put some music and video on it and all was fine. I've had it plugged in a few times and it worked perfectly fine again. Last night I tried to plug it in again to put stuff on it and all that happened was the beep you get to let you know that something has been put in the USB. It is not shown in My Computer or iTunes, and there is no USB error balloon popping up. My iPod screen still says do not disconnect when plugged in and it still plays normally when unplugged. I do not know what to do to remedy this problem and I have tried many things and looked up and down the support section of the site, but to no avail.

Have you tried assigning your iPod a different drive letter? See these instructions below:
Log off of any other users on your computer (and disconnect any iPods that are currently connected to your computer, as well)
Then, put your iPod into Disk Mode, then follow these steps:
1 - Don’t plug in your iPod yet.
2 - Go to "START -> Control Panel -> Admin Tools (if you don't see this, click on "classic view" button on the left panel) -> Computer Management."
3 - Click on the "Disk Management" button in the left panel area.
4 - Now, with "Computer Management" and Control Panel windows opened, reset your iPod, and connect it.
5 - Right-click on your iPod's listing there (after a few moments when it gets recognized in this drive window), and click on "Change Drive letter and Paths". Then the "Change..." button.
Assign your iPod the letter "M" "N", "O" or the like (further along in the alphabet).
For more details, see this article:
Windows confuses iPod drive letter / Changing drive letter
If your iPod isn't recognize to assign it a different letter, or the above steps still don't work, then try disconnecting all other USB devices from your computer (other than your mouse and keyboard), and see if you can re-assign your iPod's drive letter works.
I hope that helps you.

Solved! NTFS-3G Issue on Mac Maverick when plugging a hard drive via USB

This issue can be solved in less than 5 minutes, but it is not free. if you are willing to sort it out once and for good, read on, it’s well worth it!
“I love my Mac!”, that is a common expression you might hear everyday, but not many people are willing to admit that Macs really suck and become a nightmare the moment you plug a hard drive, new or filled with those important files, via USB. Apparently most commercial backup hard drives are formatted with Windows file systems by default and Macs will only be able to read the contents of these discs after properly formatting them on Mac.
I have 3 external hard drives filled with mp4 movies and uni files, and formatting is absolutely a no-no here. So I was forced to open those files using the Windows virtual machine (via Parallel) in my Mac, which really ***** too. According to the many websites I visited for solution, you either had to buy some apps or die with that NTFS-#G error message when plugging a USB hard drive. There is also an encouragement to either format the drives on Mac before you can use, and again, in my case, this is impossible.
“NTFS-3G could not mount /dev/disk1s1 at /Volumes/Vuakalevu because the following problem occurred: dyld:
Library not loaded: /usr/local/lib/libfuse.2.dylib Referenced from: /usr/local/bin/ntfs-3g
Reason: image not found”
I think I just solved that issue once and for all, but nothing comes for free, as in anything with Mac computers. The “Paragon NTFS for Mac OSX”, which cost me $19.99 from their official website seems to have sorted me out, now I can plug any hard drive, no matter the format, and Maverick will read it as it should (read and write). Well worth it, and i do recommend it.
This was originally posted in my website, so feel free to come around if you like.
http://journalsfromoceania.com/solved-ntfs-3g-external-drive-issue-solved-for-19 -99/

Hi Linc Davis, yep! i did everything according to read me, tried all free ones, only made it worse. uninstalled the whole lot, didnt work either. I read around in forums the same thing "simply remove the app causing this issue and it will be sorted" didnt work for me. this Paragon sorted me out after 2 years of external hard drive issues. Im not sure if your reply was an assertion or a question though. cheers

How to make external devices (like iPods, etc.) NOT mount as connected drives when plugged in via USB to a Mac?

If I plug my iPod (or a thumb drive or whatever) to my Mac's USB port, the device appears as a icon representing a connected drive on my Mac's Desktop.
This is normal, expected behavior.
HOWEVER, in some cases, I'd prefer that the device not "mount" as a connected external drive.
With thumb drives or external USB drive, of course, I want them to "mount" so I can transfer files on or off them -- that would be the only possible reason to connect an external drive like that.
But with other Apple devices like iPods or iPhones, there are TWO possible reasons to connect them to a Mac: either to "sync" them or transfer files on/off them; OR, to simply recharge the device's battery. (Or, both sync and recharging functions at once.)
For those people who use their Apple devices in ways that require transferring files (i.e. most people), then having the device "mount" as a connected device is a desirable behavior.
But in my circumstance (and I bet there are a lot of people in a similar circumstance), I have no need or desire to transfer any data to or from my device every time I plug it into my Mac: I'm plugging it in SOLELY to recharge the device's battery.
Specifically, in my case, I have a 6th-gen iPod Nano, and I use it exclusively as an FM radio and a pedometer. I don't have any mp3s or songs or any other external files loaded on it, nor do I plan to add any in the future.
The only reason I ever plug it into my Mac is so that I can recharge the iPod's battery.
But the "problem," which is a minor one I admit but a problem nonetheless, is that every time I connect the iPod to the Mac, the iPod appears as a "connected drive" icon on my Mac's desktop. Which means that I'm not supposed to just unplug the iPod when I'm done -- first, I have to find its icon on the Mac Desktop, and then drag the icon to the Trash, to "unmount" it -- and only then can I freely unplug the iPod without getting an error message telling me that I shouldn't just disconnect connected drives without first properly unmounting them.
This would be bothersome enough if I only had to do it once per connection, but in the case of the iPod Nano, there's no way to tell how recharged it is while it is in the act of recharging, so that to see if I'm "done," I have to unplug it, check the battery status, and if it's not fully charged, re-plug it back in. So that each time I recharge it, I often have to unmount the drive several times, depending on how impatient I am.
There has to be a way to prevent the mounting of the drives of devices that one is connecting simply for the purpose of recharging. But how?
Strangely, I also have an old iPhone, and when I plug that in for recharging in the same way, it DOESN'T appear as a connected drive on the Desktop. I'm not sure how I managed to do this, but long ago I must have changed some setting or preference for this to happen. And by now I've forgotten what I did.
I'd prefer that I could change the "mount/don't-mount" setting on a device-by-device basis -- i.e. make it such that this particular iPod doesn't load, but perhaps a different iPod would load -- but if that's not possible, then is there a way to stop ALL iPods and iPhones from loading as connected drives when plugged in?
(I'm not talking about appearing as connected drives within iTunes -- I'm talking about appearing as an icon on the Desktop in the Finder.)
And please don't tell me to just buy a wall charger! I prefer to recharge off my computer if possible, using the charging cord that came with the iPod.
I presume there's some simple setting to toggle this on or off, but I haven't yet found it. Any clues would be appreciated. Thanks!

Well, I already know about that Finder Preferences option, but that is not what I'm looking for. Why not? Because I still need CDs and DVDs to appear on the Desktop and mount properly! If I uncheck the "CDs, DVDs and iPods" option, then I lose the ability to access CDs and DVDs, which creates a whole new problem for me. What I want is to not mount iPods only -- actually, what I really want is to not mount this particular iPod -- but if that level of specificity is not possible, then I want to exclude just iPods from mounting, without also condemning CDs and DVDs (or whatever) to invisibility.
Also, I was confused by the way the Preference is worded: It says "Show these items on the Desktop," with a series of options to check. But this phraseology seems to mean that the unchecked items will still "mount," they simply won't appear as Desktop icons. One would still have to "Eject" them using a menu command, rather than dragging the icon to the Trash -- right? Or am I mistaken, and is the Preference Pane simply badly worded, and when they say "Show these items on the Desktop," what they really mean is "mount these external devices as connected drives." So that if a category is unchecked, then they won't load as external drives at all?
But if so, then what purpose could possibly be served by inserting a CD or DVD that is not recognized by the computer? And if it isn't recognized, then it would seem that there would be no way to ever Eject the CD or DVD disk. Right?
Thus, if I uncheck that Finder Preference box you suggest, one of two outcomes will result:
-- Either CD, DVDs and iPods are still mounted, they just won't appear as icons on the Desktop; but they would still need to be Ejected via a menu command, which doesn't solve my problem.
-- Or, CDs, DVDs and iPods are not mounted or recognized by the computer at all, which means that if I insert a disk into the disk drive, it will get stuck there forever, since there's no way to Eject it, since the OS doesn't recognize that it's even there. Which is thereby a new problem.
Either way, I'd have a problem! Or...? Clarification, anyone?

IPhone 3G not appearing in either iPhoto or iTunes when plugged in via USB

No longer getting my iPhone 3G to appear as a device in either iTunes or iPhoto (my wife's iPhone 3G either) when plugged in to my powerbook's USB port or the second USB port on my Apple keyboard. Also the iPhone is no longer charging from these USB ports.
Tried different USB cables.
Wife's iPhone on iPhone 3.0. Mine on 3.1.
Then tried using same USB cables to connect via her old flat panel iMac. it worked!
Then I tried plugging the iPhone USB cable into the other Powerbook USB port normally used by my keyboard.
Nothing. Including no charging.
Looks like a problem with the USB connections on the Powerbook with the circuitry that connects to an iPhone. The keyboard works fine in either of the USB ports. And the USB ports on my 20" screen that connect to at least some of my external drives also seem to be working. They appear on my desktop.
Is the internal circuitry on the Powerbook USB ports such that some external devices can remain supported while other USB devices are not recognized?

IPnone 4s not recognized by Envy dv7-7333cl rnning Windows 8 when plugged into usb port

Laptop does not recognize iPhone 4s when plugged into any of the 4 usb ports. All usb drivers are up to date. All Win 8 and HP udates have been installed and are current. Ports do recognize memory sticks so seem to be working. Is there a special driver needed for iPhone?
This question was solved.
View Solution.

Hey texasbootz,
I'll have to get you to answer a few questions to understand what is going on exactly:
When the iPhone is plugged into the notebook, does it charge?
When the iPhone is plugged into the notebook, does it show up in device manager?
Is iTunes installed?
If it is not charged when plugged in, it is possible that the cable you are using isn't functioning properly, and you may need a replacement. Or, the iPhone itself is having some issues.
In any case, since other devices are working in all of your USB ports, it is possible that its either a software issue (with the iPhone's drivers) or an issue with the iPhone case. You'll have to contact Apple for support on either of those issues. I'd suggest trying to re/install iTunes, see if that fixes it, then to contact Apple.
Hope this helps!

Error message when plugging in usb port?

When plugging in the new ipod nano into my computer I get this message:
Power Surge on Hub Port:
A usb device has malfunctioned and exceeded the poewr limits of its hub port. You should disconnect the device.
I just bought this i-pod nano yesterday. What do I do?

What do I do?
Plug the iPod directly into the computer's usb port instead of the hub. Or, use a power hub if the one you have is not powered by ac.

Had the same issue. Tried everything that was posted for troubleshooting bye apple and on the discussions.
Finally, tried something that solved it and it works flawlessly now. I changed my wireless router.
I was using my ISP's supplied ZyXEL PN660 ADLS2+ with Wireless N. Swtiched to an older Linksys WRT160N and it is working beautifully now.
Take a look at your router, make sure the firmware is up to date, and that UPnP is enabled, and if all is correct, and you have done everything else, try another Wireless router if you can.
