USB key keep connecting and disconnecting

Hello,
I've recently bought a Satellite L655D-12P computer and I have a Sony USB key ( USM8GL).
The issue is that my key connects itself to the PC, then disconnects, reconnects etc... and keep doing the same thing indefinitely every 5 seconds.
I don't understand why the 2 medias don't work properly. They seem to work well independently:
- My USB key (USM8GL) work well on XP, Vista and other 7 that mine
- My sister have the same model of USB key (USM8GL) and it's the same issue. Good for XP, Vista and other 7 that mine.
- I've another key (Sony Microvault 4 Go) which works good on my PC (and others of course).
It seems that something's wrong. Maybe a program that is not activated.
I've of course looked a little on the internet but I didn't find anything.
Once, I succeded to make work the both media together. I succeeded to change the letter of the key in the 'Computer' (H: --> L: for example). I had to do it very quiclky because the key keeps connecting and deconnecting every 5 seconds.
But I don't know why, it stopped working after about 10 tries.
So, of course, I would like that you help me. What can I do to fix this problem? That's really annoying...
Thanks

In my opinion there is not much you can do about it. Either it works or not.
Fact is that there is no special driver you need for it.
Try to connect other USB sticks for testing. Check it with SanDisK. It is the best and really high quality product. I am 100% sure it will work properly.
By the way: does the same happen on all USB ports?

Android / USB devices keep connecting and disconnecting on R7

My daughter has an R7, and she is having a weird problem with the USB ports on it.No android device can stay connected. As soon as you plug it, it makes the connect sound then the disconnect sound and keeps cycling between connecting and disconnecting. It is not related to the device as I have tried two different phones and one tablet all with different cables, all work fine on other computers. And I tried on the three available USB ports of the laptop, all behave the same. Searching online I found a lot of people with similar issues mostly unresolved. I did disable the USB suspend option in the power options without any results, as well as uninstall all USB hub so they would be reinstalled at boot time, and installed all optional windows updates. She is also experiencing another issue on her USB ports, we have a Samsung slim external DVD player that uses a Y USB cable for data and power that also works fine on any other machine. On her R7, when playing a Video, the video keeps making blocks at regular intervals like something is preventing the full data stream. Wondering if this is related. Apart from that, USB mouse, USB keys or external USB drives appear to work fine. Anyone with a similar issue and a definitive fix?

Thanks, but I seem to have found a solution to both issues. 1) Regarding the android devices that kept disconnecting and reconnecting, after readiong this threadhttps://support.microsoft.com/en-us/kb/2900614 I checked what registry keys were present on my wife's surface pro3 for
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB\VID_XXXX&PID_XXXX\YYYY\Device Parameters and found that there was three DWORD values in there that were not present on the R7SelectiveSuspendEnabled
EnhancedPowerManagementEnabled
DeviceSelectiveSuspended So I added these 3 DWORD and set them all to zero, and the issue is gone. You may not need the three of them, but I have not tested them one at a time yet. 2) For the External DVD blocky playback, it turned out to be quite trivial. Someone had enabled hardware acceleration in the VLC player settings. I reset all the VLC settings, and it worked fine from there. Hope this can help others

My ipod keeps connecting and disconnecting from the computer

I've tried everything, first my ipod kept displaying the folder with the exclamation mark, then a couple of days ago started working again. It then wouldn't play any songs and just kept skipping. So I plugged it into my computer to restore it so I could start again. Now its displaying the folder with the symbol again, and just keeps connecting and disconnecting all the time so I can't do anything to it. Keep trying the ipod updater but says it cant mount ipod.
Any ideas????

Hello all,
I've been experiencing the same problem, but have managed to get it sorted.... well sort of.
As Jen's problem, I had the exclamation mark and after unsuccessfully trying to update etc decided to leave it out of frustration.
A day or so later it started to work again, great!!!
A few days of problem free use then I got the sad Ipod screen.
After checking the website I've restored and I'm now a week later and still trying to get my music from Itunes onto my Ipod.
The problem now, once again very similar to Jen's is that my Ipod only seems to connect to my PC for period of time and then disconnects, sometimes updating a few songs.
I get different 'Unknown Error' messages usually -124.
I've tried with both USB and Firewire connections and even when my Ipod disconnects it still charges, so it's not the port at fault.
Can't help but think it's the actual Ipod which is causing me this hassle and musicless journeys!!!
Any ideas?

Why does my iPad keeps connecting and disconnecting from the new late 2013 iMac

Hi there,
I've recently bought a new late 2013 iMac and ever since then I'm not able to connect my iPad 2 to it. When I do connect it keeps connecting and disconnecting again and again for some reason. The cable is fine and I've tried it with other devices. Just wondered why this is and whether you guys can help me out.
Thanks a lot!

Hi,
I had the same problem and just found a solution. I tryed restoring all content and settings on the iPad (Settings > General > Reset > Erase All Content and Settings). It took lots of time, however it didn´t work because when I connected the iPad and iMac the problem persisted.
Then I thought it wasn´t an iPad problem but iMac OSX problem. So I searched the web for "Reinstall Mavericks" and found this http://support.apple.com/kb/PH13871?viewlocale=en_US&locale=en_US.
It also takes like 6 hours with my internet speed. Next day I connected the iPad and everything is just fine.
I described both processes because I don´t know if in the end the iPad reset helped in the solution.
Hope that helps! good luck

IPhone 4s keeps connecting and disconnecting from my new Macbook Air 2013

Ok I've been having this problem, I recently got an 11 inch Macbook Air 2013 and after I try connecting my iPhone 4s it keeps connecting and disconnecting every 1-2 seconds. I already check the community, I know this subject has been asked many times. Nothing worked out though. My cable cord must be fine because it works perfectly on my PC. I updated the OS and iOS to their latest firmware and still nothing. Whenever I try opening iTunes I get this message saying " iTunes could not connect to this iPhone. This device is no longer connected. " Please if anyone fixed this issue I would appreciate some help. Thanks in advance.

I just solved it, I hope this helps everyone who is experiencing the same problem. Apparently the iPhone seems to charge normally and connect to iTunes if the iPhone battery is over 60%-70%. This must be a power issue the MBA has.

My ipod nano (6th gen) keeps connecting and disconnecting itself from my computer can anyone help?

I have read numerous posts online about the same problem but can't seem to sort mine out. I've tried changing power leads, restoring back till an older version of itunes, resetting the ipod, restarting my computer and tried every USB port in sight but still nothing.
I have plugged a friends ipod touch into my computer and it connects and appears in itunes fine, but with mine it wont stay connected long enough for me to try and restore anything with it on itunes its literally a 1 second interval between connected and ejecting. I thought maybe it could be the connection terminal on the ipod but i have had it connected to a wall charger and xbox with it staying connected with no problems.
I am running windows vista on the computer and the nano was previously synced to a different itunes could this be the problem and if so how do I go about fixing it??
Thanks

I too am having this same issue. I connect my iPod nano (6th gen), and it appears for anywhere between 1 to 10 seconds and then automatically ejects.
I'm running a macbook pro with OS X 10.6.8 and the most up to date version of iTunes. The strange thing is that the nano works fine on my old macbook from 2007; which also has the most up to date iTunes but is running OS X 10.5. Another thing is that my iPod touch works just perfectly on my MacBook Pro.
I have read up on a lot of forums, and have found little help for those who are running into this problem on a Mac. The majority of fixes are for PC. Any help would be greatly appreciated.

Ipod Nano 4GB Keeps connecting and disconnecting every few seconds

when i plug the nano into a usb port... it shows up everywhere and then disconnects and then reconnects and keeps doing this, therefore i can update my ipod?
Also... the ipod works fine on the xp pc next door so i have to assume its the USB on my pc.
Running Windows Vista RC2

My 80 GB iPod Classic is having the same problem -- when I connect it to the computer, it syncs as it should and then when I attempt to disconnect it, it starts syncing again. It does this no matter whether I disconnect through iTunes or through the desktop (i.e., dragging the iPod icon to the dock to eject it). This never happened before a software update last week. I forget the update but it was something to do with the Intel processor, I think. My date and time was also screwed up but when I woke up this morning that was finally ok.

Headphones keep connecting and disconnecting.

Hi there.
I've got the Sony Xperia Z3 Compact phone, and I have had no problems with it up until this week. My headphones have started disconnecting and connecting themselves. The slightest tap or even moment makes my music stop will listening to it, as if the headphones have been disconnected. But they are still plugged in. Even if I move my phone slightly to the side the music completely stops as if it's been disconnected.
Does anyone know if this is fixable, or is my phone completely dud?
Thanks in advance!

I think you should contact your local sony team:

Ipod keeps connecting then disconnecting

I've tried everything possible to try to make my Ipod mini work. I can't connect it to the PC because it keeps connecting and disconnecting repeatedly. I can't restore it since I can't connect it. I've tried all the different USB ports and I've installed and uninstalled all the programs a few times. I've also reset it connected and disconnected. It has worked before but now it won't! This is driving me nuts

Similar problem here too plus when I do manage to get them to connect they will not charge.
Both my classic iPods work fine, in all my computers, and show that they are charging, but my family have 3 nanos, a 4th and two 5ths. Although they all connect to my PC and my laptop fine, none of these will connect correctly to my daughters PC no matter what USB port I put them in.
I have checked in device manager that the ports are powered (500ma) and nothing else is there to infringe on this supply. Still these items connect and disconnect constantly. Ironically every now and then, they will connect and allow me to look at the files etc in iTunes. I have at one point had two nanos and my classic connected to her computer and they all worked fine for about an hour, I thought that I had finally got rid of the problem but one by one the nanos started to play up again so this exacerbates the problem somewhat.
I also get various warnings when the Nanos are trying to connect like, software driver failure to install, it will work faster in a high speed USB port, nano needs formatted to work in windows plus a host of others. When I plug them back into my PC they connect fine, so that all adds to the confusion. If this was one nano I would suspect that it was faulty but it is three different ones.
I have done the 5 Rs, I have even gone as far as upgrading from XP to Windows 7, I have plugged the units into every USB port, I even bought a new PCI/USB card and tried that and still this problem persists.
I would like to hear from someone with any suggestions as to what is causing this and how to fix it.

Obviously, syncing an iOS device with iTunes over USB is still supported in Mavericks. Calendar and contact syncing with iTunes is no longer supported. That has nothing to do with your problem.

Windows won't install USB device...infinite loop of connect and disconnect

I've been very happy with my Ipod purchases over the years but this one is the worst problem I have ever had. Purchased an 8gb Ipod Nano 3rd gen for the wife as a Xmas present and went to install it on my PC today but no luck whatsoever. The PNP manager seems to go into an infinite loop of connect and disconnect with the odd "Itunes has found a corrupt player ...." message but the device won't stay on the PC long enough as it promptly disconnects from the PC again!
My other 3 Ipods all connect and work quite happily on this PC, I've tried a few of the other "solutions" that seem to fix other "problems" but as the device does not stay connected for long enough I can't do anything with it!
Has anyone else had this problem and been able to fix it? If so, what did you do to correct the problem?
thanks
Marty

Thanks, tried that and much more - a very frustrating process.
I've just posted this on another thread...
I've tried unplugging everything and it still didn't work (I only have a USB printer, USB 1.1 hub and a USB phone connected). Funnily enough though connecting it to the USB 1.1 hub it works OK - go figure. Connecting directly to a USB 2 connector either on the front or rear panel and my PC goes into the connect/disconnect loop! My 1st and 2nd gen Ipod nano's and my Shuffle all happily connect to the USB 2 connectors on the front panel but the 3rd gen one does not want to know.
I think that Apple have got something seriously wrong here and it would be nice if it was acknowledged and a proper fix applied.

My iphone 4s connects and disconnects (repeatedly) when connected to my computer

my iphone 4s connects and disconnects (repeatedly) when connected to my computer, it works perfectly fine when connected to regular chargers, everytime i connect it to my computer it shows the charging symbol and then disconnects and reconnects in less then a second, it will repeat this process forever unless disconnected, sometimes it works perfectly fine and most of the times it does the same thing, I know for a fact its not the wire because i recently bought an ipad mini with retina and its usb is new, it worked with the retina for a day or two and then it kept connecting and disconecting repeatedly, my computer is two months old and i have new hardware in that machine, is it a problem in the usb power fluctuation? i am currently using windows 8.1 and i need solutions, this is super annoying, all my other devices work perfectly fine with the usb ports, all my usbs (2.0 and 3.0) do the connecting and disconnecting sometimes it even works ,what is the problem?
