Closed-lid mode USB devices disconnect randomly

I just recently connected my MacBook Pro to my Samsung DLP HDTV and started running it in closed-lid mode so my TV is the primary/only display. I also have an external hard drive (USB), external mouse (wireless with USB toggle) and the new Apple bluetooth keyboard.
The problem I have isn't entering the closed-lid mode. But once in closed-lid mode (after a short period of time) all of my USB devices disconnect and then reconnect. I know this because I get an error saying that my hard drive was removed improperly (please eject before disconnecting, etc) and I also get a message from my mouse software saying that my mouse has been disconnected. But then they reconnect themselves (hard drive shows up again on desktop and mouse software informs me that the mouse is present again).
Has anyone had this problem before where USB devices disconnect in the closed-lid mode? I just upgraded to Leopard (formatted the drive and started from scratch). I never tried this within Tiger so I don't have that for a reference. This is really annoying because I have my entire music collection on the external hard drive and it just stops playing when this happens and I have to restore the path to my music collection within iTunes' preferences (it defaults back to ~/Music/iTunes/ when it figures out that the hard drive is no longer there).
The strange thing about this is that when I don't run in closed-lid mode this never happens. I'll be more than happy to provide more details if needed. I greatly appreciate your help.
Thanks!
Mike

i appear to have the same problem under Vista (via Bootcamp) on MBP (2007). i close the lid, and 5-20min later i hear the sound a USB device makes when it disconnects, and a minute or 5 later it reconnects. i don't actually have any USB devices plugged in, but there are several components in the MBP that are connected internally via USB (DVD drive, etc).
what's almost as annoying is that the LCD backlight will come back on of its own accord, even though the MBP's been idle for more than the LCD/backlight time-out period. after the next idle timeout it turns off, only to turn back on againa while later. i see this under OSX & Vista.

USB mouse disconnects when laptop on battery

Hello,
I am using Gnome 3.6 on 3.6.10-1-ARCH. Whenever I run my laptop on battery power, my external usb mouse disconnects after some inactivity period. If I plug it to external power source, it again starts working fine.
I suspect there must something in gnome 3.6 (weird optimization) or something to do with laptop-tools which disconnects the usb mouse after some time of inactivity to save power. How to fix this.
I referred this link, but it did not provide me way to fix this.

Update: I noticed that I had not enabled laptop mode tools so problem must be with gnome3. I have now enabled this and set my USB mouse id in blacklist, so that it does not autosuspend. Still It is getting auto suspend.

I imagine that your usb ports control is set to auto... which will suspend the device after a time of inactivity. The solution would be to have this not set to auto... though I am not sure how to do this with laptop-mode-tools in place. I don't use laptop-mode-tools, and it is my opinion that it actually makes things harder when you encounter things like this. Instead of learning where the configuration for this is within /sys and then creating the necessary configuration to change it, you now learn where it is in /sys, what is changing it automagically for you, then you have to learn the intricacies of that particualr power management tool.
So although I cannot help you with yout laptop-mode-tools, the file that sets this is /sys/bus/usb/devices/usb[1-9]/power/control or /sys/devices/pci0000:00/0000:00:1a.0/usb1/power without the symlinks on my machine for usb1.
Just my opinion, but with the power that comes in computers these days (for the past several years in fact), having something like laptop-mode-tools is pretty worthless. If you just have all the settings set as though it were on "battery" all the time, I bet there would be no discernible difference. I know I cannot tell, and then my computer probably charges ever so slightly faster because it is not set to consume more power when I plug it in.

Usb keeps disconnecting n97 mini

its impossible to install to or backup from my n97 mini. Everything is fine until an installation or backup and then i get the rror that usb is disconnected half way throuhg. Happens on both ovi and pc suite. Any help on this?

I've had my share of "fun" with connecting devices to my pc's. Faulty usb cables, faulty usb ports, driver issues, other funny issues with the OS not detecting the device, 3rd party programs messing up everything etc. This "manouvers" mentioned above are no absolute solution. It might work sometimes. Often a reboot of the pc seems solve a lot.
I'm glad it helped some of you anyway! And for the love of, I'm no genius. Such alternating between how to connect, reboot etc is just something I try when I don't know better.
Also, Pc suite and Ovi suite seems to dislike each others. I try to stick with one of the programs.

Hi, clara_from_brazi.
Thank you for visiting Apple Support Communities.
Here are some troubleshooting steps that I would recommend when experiencing this issue. Also, test connecting the external storage device to the computer with another cable as this can be the issue.

E71 update problem - USB keeps disconnecting

Hi,
I am trying to update my phone (E71)'s software through the Nokia Suite or whatever on the PC but when it gets to the installation process I am unable to continue because the USB keeps disconnecting every five seconds.
Is there any other way of updating this model?
I've had it for four years so maybe it's just too old and forgetful to be updated

FOTA was never implemented upon S60 3rd Ed FP1 devices so either try a different Windows PC or a Nokia Care facility.

Disable wake-up on USB connect/disconnect

Hi,
I have a USB hub with a few constantly powered slots which I use to charge and sync my iPhone. The constantly powered slot allows me to put iMac to sleep and keep the iPhone on charge. However, there is one problem - connecting or disconnecting the iPhone causes Mac to wake up. Is there a way to disable wake-up on USB connect/disconnect, but keep it on keyboard?
Thank you,
DB

You could use a special iPhone cable that lets you disconnect the sync pins for charging only.
<http://www.usbfever.com/indexeproduct_view.php?productsid=1367>
When set for charging only, it shouldn't wake the computer when you connect or disconnect the iPhone.
(Don't move the switch while the phone is connected.)
Have you checked that the phone is actually charging when the computer is sleeping? Some USB hubs may not provide full power if the computer is sleeping.

Macbook Pro right USB port disconnects

Hi - When using the dialup modem adapter in the right USB port it will disconnect after 3-4 minutes but works fine in the left port. Flash drives & scanner seem to work OK in the right.
Also, a friend has computerized embroidery sewing machine and the right port does not recognized it but the left does on her MAC.
Are Macs were bought a couple weeks apart.
Is there a setting for each USB port that maybe wrong or is this just a defect?

Well, does that link...

still lock up your Mac? No way it should have any such effect.

IDEAPAD V460 - USB port disconnects randomly

Hi Community,
I am in a trouble with my IDEAPAD V460, 59 - 044185 (4th one from the beginning) which I purchased around a couple of years back. It was working fine without this annoying issue until recently. This partiular model comes with three USB ports, two on the left side, one on the right side.Since around last 15-20 days, any device plugged into any one of the two USB ports on the left hand side of the laptop is getting disconnected randomly. I use an iBall 4*1 USB hub to connect one keybaord, one mouse and one modem to any one of the USB ports on the left side. Initially I thought it to be a software issue. But reinstalling the OS or even switching over to other OS did not solve the issue. To probe more, I refrained from using the hub and connected two of the mentioned devices directly to the left side ports. Still, the problem persists, but the frequency of disconnection is less. Sometimes, the devices gets reconnected, sometimes do not. That is also in a random fashion.
One of my friend having a Y500 model also having similar issue. As you can understand, given the number of USB devices we use everyday, it's hampering my day-to-day activity.
Two years being passed, I am out of warranty. I found that there are so many people around here also having same or similar issues. Presently, my perception is that those to USB are not being able to pull out enough power to maintain +5V and causing this random disconnect. Any idea what to do?

Usb stick disconnects itself but is still connected

i have a mac book pro. when i use a usb pen drive or multi card reader. every now and again the computer brings up an error saying it is disconnected but it is still plugged in. i had a usb pen drive this is no longer accessible due to this problem.
any ideas

Hi,
When connecting to your network via the computer, insure you set sharing to enabled. Turning off sharing when connecting to your network in Win 8 can sometimes cause a disconnect

Time to take it back in for repairs.

All USB drives disconnect after upgrade and clean install of MAC OS X Mavericks

I first upgraded to Mavericks and noticed that my external USB dries would disconnect after MBP Retina Mid 2012 model was updated to Mavericks. These worked fine in all versions of Mac OS X before upgrade. So I did a clean install figured my machine would benifit from this anyway. This did NOT fix the problem.
Wouldn't be much of an issue but I use this macine as a media server with Plex and all the media is in one of the external USB 3.0 drives. All drives are from Seagate, and have found no info there. Guessing this is a bug that Apple needs to fix unless its a Seagate issue which I doubt.

If the tracks are recognized by your iPod (playable), search VersionTracker for "iPod". You'll find a number of utilities that can transfer your tracks and your playlists from your iPod back to your Mac.
If they're just on your iPod as data, then I'm not certain since I don't use a custom hierarchy, but you should be able to copy the folder back to your iTunes Music folder, turn off the "copy to iTunes library when adding to library" preference, and then use the Add To LIbrary command to get them recognized by iTunes. Again, though, I don't use a custom hierarchy, so you might want to ask that question as a new post, just to get additional opinions.
BTW, an iPod is not a reliable backup for your tracks. Too many situations can arise that would cause your iPod to need to be erased. I strongly recommend that you make backups, particularly of any tracks purchased from the iTunes Music Store or that would otherwise be difficult to replace, to CD, DVD, external hard drive, or other medium.

Player blocks when USB Headset disconnected during playback

I am playing a Wav file in my application & using a USB Headset to listen to the playback.
I'm observing the following behavior while doing this:
Scenario-USB headset is connected when the application starts up.
a) Am able to hear the voice on the USB headset when I play the wav file. Also, I get the visual Control Panel component for the player and add it to my application UI.
Code Segment 1:
//create player
//start playback
//player.start();
Code Segment 2:
//In controllerUpdate(ControllerEvent ce)
//for RealizeCompleteEvent
if (event instanceof RealizeCompleteEvent) {
//get the Control Panel Component for player
Component comp = player.getControlPanelComponent()
//add the component to the UI
b) javax.media.StartEvent is fired when the playback begins.
c) I then disconnect the USB Headset while playback is in progress. The saddle on the Control Panel Component slider bar pauses at it's position as soon as the headset is disconnected. Also, when this happens, no event is fired.
d) At this stage, if I try to stop the player using a Stop button on my UI, my application hangs. The stop() method called on pressing the Stop button has the following code:
Code Segment 3:
//in stop()
//stop player, close it & deallocate resources
player.stop();
player.close();
player.deallocate();
In the above steps, no exception is ever thrown nor any event fired signalling the disconnection of the device in use(headset).
I need to detect the disconnection of my USB headset & prevent the player from blocking, so that I can stop the player & release the resources in a clean way.
Any suggestions in this regard would be appreciated.
Thanks!

Hi, did you resolve your problem? I have similar problem to detect when a capture device is disconnected.

Usb drives disconnecting

My wifes late 2010 macbook pro has been having a serious issue with ejecting just about any usb drive connected. Shes a graphic designer and is constantly plugging and unplugging portable drives and mini flash drives, but always sure to properly eject them before pulling them. Recently (and becoming more and more frequent), the drives with just disconnect on its own and will give the warning that the drive was not properly ejected. it then immediately tries to mount again and disconnectes again. this happen no matter which drive or flash unit we use on either usb port. every drive she has had problems with works perfectly fine with no eject problems on my 2011 macbook pro, so that rules out bad cables or drives. We've also tried usb hubs and zapping the pram, but with no success. as of 5 mins ago, i just tried to connect a usb microSD adapter with a 8gb microSD card inside and it ejected in less than 30 secs and goes on an endless loop of mounting and improperly ejecting. the same usb is now in my macbook pro and is fine as i write this.
if anyone has had this issue or knows what the problem may be, please enlighten us. im leaning more towards the ports are shot....but ive been know to be wrong. any help is appreciated. thanks in advance.

I am having the exact same problem under 10.6.1 with a WD MyBook USB drive, formatted as Mac OS Extended Journaled. The drive worked fine under Leopard, but since upgrading, I cannot copy anything to it without the drive ejecting (while copying files) and then remounting on its own. Within 3 minutes, it will eject, remount, eject, etc., about 5 times.
I have repaired permissions, checked the USB drive with disk utility, checked cables, switched USB ports, all to no avail.
And I am not using a USB hub; the drive is plugged directly into the back of my iMac.
It feels like this problem is related to Snow Leopard and the "auto-sleep" features of these drives. In my gutt, I believe these drives would work if they had a proper on/off switch, instead of auto-sleep, etc.
One other thing I've noticed (sorry to ramble on): I can eject the drive, but it will remount to the desktop after about 30 seconds.
