USB Drives Not Recognized

Just received my first iMac and I'm trying to transfer data I saved off my PC. I have a Lacie Rugged external and my Samsun Z5 (my music is on this MP3 player) but neither of the devices show in the Disk Utility folder. I assume I am missing a step but from what I've read it should be "plug and play". Help and education is appreciated in advance.

My USB disk icon is also lost. I had just finished re-formating the drive to the MAC format, backed up up mail and all of my pictures - and 2 users mail files. Shutdown the system to install Leopard from Tiger. My IMAC is 20 days old ... not a lot of files.
After Leopard was fully installed and updated with all fix's, I re-connected the drive, but it never appeared. A waited for a while .. no change, so I pulled the USB cable. Leopard give me a trap like error and said to hold down the power button until powered off. When the system came back up .. its still not showing. I tried the Disk Util .. it does not see it also

USB Driver not recognized- DPC3010

Windows 7 Home premium
Service Pack 1 with a 64-bit operating System.
My apartment complex gave us all modems ( the DPC3010) and my computer will not recognize the usb cord that is supposed to hook up to the computer.
I have tried uninstalling the drivers and other weird little tips. I already installed the disk and everything on it...but nothing. The device is still not recognized.
If anybody has any advice please send it this way.

Had the same exact problem with a new laptop. Nothing worked as it just wouldnt install or recognize my Iphone. I simply took it out of the USB port and moved it to a different port and it worked. It recognized the iphone and works great.
I then (just to test) plugged it back into the other USB port and it would resort back to "Unknown device" with no Apple Moble Device driver shown.....
Anyways hope this helps....

USB drive not recognized in fresh Windows 7 installation on MBPR 15 via bootcamp.

I'm trying to install Windows 7 Ultimate on my Macbook Pro Retain 15 via bootcamp. I've gotten all the way through the Win 7 installation and now am able to login. However, Windows doesn't detect my USB drive that has all the drivers. (It's already FAT32).
I'm stuck with a Windwos installation that can't get online and can't do anything. How do I install the basic drivers? My hunch is that the Macbook has all USB 3.0 slots and Windows doesn't have those drivers by default.

Assuming your original image files are on a seperate drive to the boot drive then Copy or Move your catalog file (and the preview folder if you wish) to another drive, no need to export it. Just copy it back to whatever location you want once finished and open it from the new instillation. On no account re import files that are already referenced by a catalog. When you re start LR it should find the original files if the drive paths to wherever they are located remains the same, if not right click and relocate the files/folders.
LR stores the catalog file and previews data on whatever drive you specify when creating the catalog. It will default to the C drive unless you say different. The locations of preferences files, templates etc. are by default on a windows installation at user/username/AppData/Roaming/Adobe on the C drive. Obviously the image files themselves can go wherever you wish.
It is usually best to locate the catalog on a different drive to the OS and applications where this is possible. However if your SSD drive is large enough the performance gains from having the previews on the SSD may outweigh the performance gains from having them on a separate drive, it rather depends on how much space you have on the SSD.

External USB drive not recognized in OS X after rebooting from Boot Camp

Thanks in advance for any help. Here's the situation:
Everything works fine in OS X (10.5.2). In particular I have an external USB harddrive that I keep my iTunes songs on.
Then I boot via Boot Camp into Windows XP and play a few games. Then I reboot out of XP and back into OS X. At that point the external USB harddrive does not show up on the desktop. If I turn off the harddrive and turn it back on again, it shows up and is usable. I can continue to do that, but I would appreciate any advice on how to get the harddrive to show up when rebooting from XP (without requiring it to be turned off and on).
Thanks!

I've surfed around already before having my problem posted here because it's so frustrated…
AnaMusic: I've tried that but it isn't worked
Eric Ross: it's checked
LexSchellings: I did run "verify disk" and "repair disk" -> but no luck… My hard drive isn't mounted to Lion as shown in status. Is it something to do with NTFS format? I came across some forum and read that Lion is design to natively support NTFS..
Are there any ways around???

USB external hard drive not recognized by computer - using WRTSL54GS

Hi, I have my router (WRTSL54GS) set up and seems to be working ok, but the computer does not recognize it in my network. It only recognizes it as a wireless connection. Also, the USB hard drive I have attached to the router is not recognized anywhere on my computer. What am I doing wrong? Any help would be appreciated!

hi - thanks for responding! I have comcast and have their modem. I hooked up the router with my laptop and went through the setup fine. Everything with that works ok. The USB drive is recognized on the web based utility program that you use to set up the router. However, no where on my computer can I find the USB drive or where to even set up that driver. The manual says that my router should be listed as a another computer in my network neighborhood and that I should be able to find the hard drive through that. It is not. Its only listed in my wireless connections. I talked to a rep at linksys for awhile. In the end, they just suggested unplugging it and plugging it back in......that didn't work! Does that help?

USB flash drive not recognized on desktop or disk utility

I see a number of similar threads to this but nothing solves this problem. Any help will be greatly appreciated as I am about to go crazy!
I have 3 USB thumb drives that all worked 2 days ago - now only one does. I have tried all drives in multiple ports and the same result. I have restarted the iMac (2009 Yosemite) a number of times and the same result.
This came about attempting to create bootable USBs with each of these. I was struggling with the process on my mac so took 2 (brand new 16GB PNYs) to a PC created the live boot USBs and they booted fine on the PC (knowing this wouldn't boot my mac). I did however plug them into my mac and they were recognized. I finally found success creating a Ubuntu live boot with my old USB. With that success I wanted to try with one of the new USBs on the mac.
Here is what I did:
1. Using Disk Utility - Reformatted the drive 1 partition MS Dos FAT 32
2. In Terminal unmounted the drive and ran a dd command to copy the linux .img file successfully
3. Box came up saying drive not recognized and selected to ignore (this happened on my old one that still works also)
4. Ejected drive from terminal
5 Restarted mac and attempted to boot from USB without success.
After this the 2 new USBs were no longer recognized in any usb port while the other still is. They do not show on the desktop nor in Disk Utility. I checked them on the PC and they are still both recognized and showing the FAT 32 format.
Help please!

Thank you for the reply. I found some time to go through this process a number of times without success
Any other suggestions?

USB Device Not Recognized

Operating system: Windows Vista
Error: USB Device not recognized
While actively on the computer, we suddenly got a message stating that the USB Device was not recognized. The only thing plugged in to the USB port was a mouse. Tried all the ports, same message. Tried another mouse, same thing. Tried a thumb drive, and low and behold, 2 of the 3 USB ports worked. Tried a URL from MS which is supposed to help with this exact problem and possibly fix it: http://windows.microsoft.com/en-us/windows-vista/Tips-for-solving-problems-with-USB-devices
This didn't work.
Contacted HP support and they wanted me to restore back to a restore point as well as updating my BIOS. After searching the issue more extensively using Google, I found that several people said to do this:
Shut down the computer
Remove the power plug
Remove the battery
Put the battery back in
Power up the computer (without the power plug)
This forces a hard reset.
Almost as if by magic, the problem disappeared. A much simpler and less technical solution to the problem than what HP recommended!!!!

TS1369 Hello! I have an Ipod Shuffle 2nd Generation and it is not recognized by my Windows 8 based laptop. An error message of 'USB device not recognized' is shown. I have the latest ITunes version installed, and tested the dock in other pc's.

Hello!
I have a problem connecting my Ipod Shuffle 2nd generation to my Windows 8 based laptop. The computer doesn't recognize the Ipod and issues an error message saying 'USB device not recognized'. I tried uninstaling ITunes(latest version) and all other Apple software and reinstaling it back again, checked my USB hubs in the 'Device Manager' section of the Control Panel, you name it.
I could really use some help solving this.
I've turned to the troubleshooting section in Apple Support but it has nothing concerning situations in wich the device isn't even shown in the 'My Computer' folder.
Help a brother out, will you???

Found a solution in another forum http://en.kioskea.net/forum/affich-63733-ipod-not-detected-on-computer (a few posts down).
It was for an IPOD so you can see those details in the link.
Found how to reset a shuffle and inserted it into these instructions - did not have to follow his last steps.
- Turn off computer.
- Plug Shuffle into usb.
- Then you must reset your shuffle
To reset iPod shuffle:
Disconnect iPod shuffle from the computer (if connected).
Move the switch on the iPod shuffle to the OFF position. Note that when iPod shuffle is off, the green stripe by the switch is not visible
Disconnect iPod shuffle from the computer (if connected).
Move the switch on the iPod shuffle to the OFF position. Note that when iPod shuffle is off, the green stripe by the switch is not visible.
- Start computer and it should install the usb driver for the ipod automatically.
- Your i pod will say do not unplug so don't. then open itunes and it will be there.
I did not have to do these thing below – did not get error message and shuffle was displayed in Itunes. / LMc
Just remember to not only eject ipod from itunes but stop usb.
Go to the program icons near the clock and right click the usb icon and "safely remove hardware" will appear and click it.
Stop it and select "apple ipod".

"USB device not recognized" when ipod plugged in???

(ipod mini 4gb)
When I plug my ipod into my laptop I get the message: "USB device not recognized." It says the device has malfunctioned!!! If I click on this error message it says my ipod is an unknown device and no drivers are installed for it???
It was working fine until a few days ago. If i reset it I can charge it up but that's all, it still does not appear in itunes or on my computer.
I've tried eveything on the help website but nothing works! Can anyone help?!
patriot 3050 Windows XP

ok my question is do you have a mac or windows based laptop
here is why and what happened to my ipod mini
my ipod mini was connected to my macintosh charging while i was using my imac and it came up with a system update 10.4.3 i installed it and finished installing it and afterwards my apple wouldn't recongnize my ipod mini or even display it one the screen i found out by myself that when the apple update got to the end of the update it installed new hard drive drivers but also installed the drivers on the ipod mini which locked out the mini's internal hard drive and my mini then stop responding it would play music and charge but wouldn't connect to the computer
so what i did to fix it was this
i went into utilites in mac os x tiger or any version of os x has this and selected disk utility you will notice that the ipod will appesr in disk utility but not on the desktop this is due to a recent system update driver that isn't compatible with the internal drive on the ipod mini so in disk utility just select format the drive in a mac os partition standard works the best it will then format the ipod and the ipod will apear in the desktop again but not as a ipod let me explain when you format the ipod using the disk utility it formats and even erases the firmware of of the hard drive on the mini so when you are done formating the ipod run the ipod updater to reinstall the ipod's operating system and presto your ipod will now work again
warning: i don't know how to fix this on a ipod in windows so if this is a windows based laptop you need to find someone witha macintosh to do this with sorry

Usb device not recognized on shuffle

i have a belkin usb 2.0 device with 2 ports. it is plugged into my ibm thinkpad laptop. the mouse works fine in both ports -as does a photo scanner. but for some reason, the ipod shuffle is not recognized - i keep getting a green blinking lite and a message that says "usb device not recognized". funny, because the shuffle worked fine the other week when i installed all the software after purchase. i've updated windows software and reset the ipod. i've read elsewhere that some people have had the same problem - and that it was a malfunctioning usb port on the ipod shuffle. if so, what a piece of junk. maybe i just need to call tech support and ask for a new shuffle - i don't think that downloading the updater, etc. will help. any suggestions? thanks.

If it's working with other computers (using the same USB cable to connect the shuffle), then the problem is probably related to your computer.
If you connect something else to the same USB port (like a USB flash drive if you have one), does it work?
If you are using a USB hub to connect the shuffle, be sure to try a port that is directly on the computer. And try more than one port that is on the computer.
Also, it may be helpful to know some other details, such as type of computer (Windows or Mac) and the version of OS.
Since this is a laptop, if it has a main battery that can be removed, you may want to try disconnecting it from power and removing the battery. Leave it that way for a new minutes. Then, put the battery back, start it up, run iTunes first, and try the shuffle again. If there was a problem with your USB ports, that may correct it.

3G iPod Touch "USB device not recognized" on any PC

My 3G been working fine for 1+ yr. Running iTunes 10 on a WinXP system; latest OS (4.2.1?) everything was up to date and working fine. One day I get "USB device not recognized" when I hook it to the PC. Also, when connected to a charger, I don't get the battery screen. It charges either way, but slowly.
I visited the local Apple store & the guru checked it on her system, with same results. I just reset it, hoping for a miracle, but it still isn't recognized.
Help?

Hi Che-Che. I'm having what looks like the same problem. Cannot get this iPod Touch 4th Gen to be recognized on any computer. When I use the white Apple cord that came with it, absolutely nothing happens. Not a sign of being recognized or not being recognized. I brought a third party cable made by Scohche and it is made for iPod, but at least the computer acts like it is starting to load the USB driver, then it fails. The other cable you are talking about, was it an Apple cable? I'm leaning towards it being a faulty Apple cable.

"USB Device not Recognized" when shuffle is plugged into computer

Everytime I plug my shuffle into my Dell laptop it comes up with the message "USB device not recognized". The shuffle doesn't show up in my computer or itunes. I've done some of things that it says to try, but I'd really like to get this fixed and get my shuffle working. Typically when I plug it in, it blinks once, yellow/orange, and then no more, and the notice comes up on the computer screen. If this makes a difference, the shuffle worked fine until last summer when my hard drive crashed. Upon installing a new hard drive, the shuffle began to not work/sync with my computer as it had been before. Any suggestions on how to get my shuffle working again? Much appreciated!

Windows won't recognize my iPod - USB device not recognized

This is really frustrating. So I got a 4gb iPod nano on Saturday, took it home, set it up and everything was going just fine, no worry's. About 4 hours later I went to adjust my songs and it would not come up in iTunes. A little pop-up box said that the "USB device not recognized - one of the USB devices attached to this computer has malfunctioned and windows does not recognize it." After owning my iPod for less than an afternoon, I now have an ipod that I can do nothing to including change the music, charge it, etc. It works normally otherwise, it just won't connect to my computer. I then plugged in my older 256mb usb stick, and the same message, it too does not get recognized by windows. So I then tried a brand new 1gb usb stick that I had and the same result, not recognized by windows. I updated my itunes to the latest one after purchasing my ipod (version 7.4.3.1) and have looked up everything that I can and tried everything I saw to try, but nothing, absolutely nothing, worked. However my usb mouse, usb joystick, and usb printer all still work, but my moniter that has four usb outlets on it causes the same message, if I plug in the cable that connects one usb on my computer to the four on my moniter, windows can not recognize it. When I look in my device manager at the "unknown device" under the usb controller list it says that there is not driver for it, however I know that the drivers are either on my computer or built into windows. Any help? Anybody have an idea about what to do? Is it something in my windows registry has changed because of the new itunes, etc.?

Now that I've had some sleep, I realise I didn't really provide information that may lead to some specific help. Here goes - when I first plugged in the ipod nano (8gb), It displayed the screen it was supposed to - I could see the lightning bolt through the battery icon and knew it was charging. The icon for the ipod also appeared in the left-hand listing in itunes (in the section that existed under Library, before the sections Store and Playlists). This section now does not appear (I can't remember the title of this section, but it might have been 'devices'). In fact, I'm pretty sure this problem started when I clicked on this icon - nothing happened and it disappeared - so did the display on the ipod, which is not just the apple. This means itunes has only Library, Store and Playlist in the left-hand colunm. While I accept that computers do not work on normal logic, this seems to me to indicate that the drivers are fine, the system is fine, my laptop is fine - its the ipod or the usb cord. This morning as I tried again, this time my laptop gave me the option to 'click on the balloon to solve the problem' - let me quote: "One of the USB devices attached to this computer has malfunctioned, and Windows does not recognise it. Try reconnecting the device. If Windows still does not recognise it, replace the device". Come on folks - one of you will surely know how to fix this (short of me taking the ipod back to the store to get my money back).
