Firewire device not recognized

After I installed Leopard my firewire pocket drive showed up on the desktop. A week later, no device on desktop. I already repaired permissions. Anyone have a similar problem? Any fixes?

Disappearing drives are a problem:

Disk Image Won't Mount - Reason: Device Not Recognized

As I've searched the discussion forums, I've seen plenty of postings for "Disk Image Won't Mount" and for "Device Not Recognized" but not the way I'm seeing it on my laptop.
After a backup and restore, my mac will no longer mount any... and I mean any images. I have downloaded several security or software updates from different vendors and each .dmg file will not mount. I still have the .dmg files in hopes that after I get this problem solved, I'll be able to install them, but...
It always gives the same reason for not mounting and I'm at a loss on what to do next. I've run Software Update hoping it will be a quick fix, but have had no success.
Any suggestions?

I have a similar problem. Using FireWire disk mode, I put a disk image of my entire iBook onto my iMac as a back-up. (For an unrelated problem, Apple told me I needed to erase my iBook completely and do a clean install of the system.) Well, I screwed something up. I don't know what exactly--maybe I didn't "put away" the device correctly, but the next day when I flipped on my iMac, the disk image of my iBook was just gone, and not to be found anywhere. I finally succeeded in restoring the image using TechTool, which scanned the entire volume of the iMac for directory information. And it's all there, because the img file is more than 10GB. But when I double-click on it, I get the following error msg: "The following disk images failed to mount...reason--not recognized." I've checked the app it's supposed to open with, permissions, and run Disk Utility volume repair. No dice. Any ideas??? Did I mention that this is EVERYTHING I had on my iBook???

USB Device not recognized by windows

When I first plugged my iPod into my computer, it went through the whole recognizing new hardware thing. Installed the drivers, then said that the new device was ready to use. But then I get a message that says "Device malfunction, device not recognized by windows" or something to that effect. I only have 3 days to return this iPod...anyone have any ideas? Thanks.

I'm not very familiar with the Windows OS but try this tip I picked on the forum up a while back, hopefully it might help.
1. On the Start menu, click Control Panel.
2. Double-click the System icon.
3. Click the Hardware tab.
4. Click Device Manager.
5. Scroll down the list of devices to the Universal Serial Bus controllers
6. Click the plus icon next to the Universal Serial Bus controllers.
7. Double-click one of the indented USB Root Hub entries.
8. Click the Power Management tab.
9. Deselect the "Allow the computer to turn off this device to save power" option.
10. Click the OK button at the bottom of the window.
11. Restart the computer.

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".

When I connect.. sometimes it says Device not recognized or malfunctioned!

Hi. When I connect my ipod to any microsoft device, sometimes my ipod doesnt connect. I cant charge it, or restore it as it behaves like a useless piece of plastic.. I get a yellow bubble 'Device not recognized or has malfunctioned'
This problem is bizarre! I cannot find anyone who actually has a solution for this problem! Apples standard answer is for me to reinstall my drivers or update itunes or windows. Done it. No solution yet.
My ipod works fine.... sometimes. Its a completely unpredictable problem. Ive googled this problem and so many ipod classic owners have asked.. solutions ive tried: the 5r's, updating drivers, It managed to connect once, but now it wont. My ipod normally works fine on my PC, XBOX, laptop and Mac.. but sometimes, unpredictably, it wont be recognized by anything apart from the mac. For a month it would not connect at all and I took it in to an Apple store where they told me it works fine. Its not my PC.. its up to date, and theres no reason why it doesnt work on my XBOX because some times it does.. last night it did, today its broken again, I suspect tomorrow it may work. This is SO frustrating!!
I have alot of experience in PC's and normally I can solve a problem by process of elimination, updating and reinstalling, but in this case.. everything seems fine. My only idea is that maybe its my Sync cable?? Which also makes no sense because it generally connects fine on the mac - and, why would a sync cable be unpredictable.. surely it either works or it doesnt. HELP PLEASE!!
Nick.

my serial for my 80g classic is 8K819CPKYMV and is under warranty until May 2009, i bought it in August this year.

there is a good chance that this can be related to bad contact in USB lead.. e.g not enough power from IPOD to PC so that pc cannot recognise it. Where I work I get alot of USB devices on pc's that are not recognised and most of the time it is the connection to the device that is not good enough because the flat end of the USB adapter has been gradually bent over time just slightly and now contact is not good. It can also be todo with drivers or If you are using it through a USB hub.
so if it is not working through USB hub try direct. also try in back of PC as these Ports or direct access to main board to pc and would be less trouble some if there was a voltage loss from mainboard in pc to front of unit.

USB Device Not Recognized on Windows 7 - USB mouse

I have a 4 week old Inspiron 1545 with Windows 7 Home premium that has developed an error: USB errors while trying to install a Microsoft USB mouse on this Laptop. Interestingly, my Microsoft USB Mouse installed perfectly first time and worked for about 2 weeks, and then failed. In looking at the system restore points, it tells me that there have been two driver updates to the USB environment since the unit was shipped from Dell. I wonder if an automatic update from Microsoft has somehow inadvertently updated or replaced a Dell factory driver.
Two nights ago I spent 45 minutes with Dell tech support doing remote control bug fixing on this laptop. They werent able to fix it (in the time allowed). They downloaded at least one of their newest drivers onto this machine and rebooted it - and they seemed pretty savvy - but still not working. So I went ahead a did a system restore to a point about 10 days back because I could see that a USB driver would be affected (as shown in the system restore menus), and I would like to compliment Microsoft on this very cool functionality!
At this point, I've unplugged the USB mouse , used the Device Manager to delete the 'unknown device', and done a system restore back to what I suspected was a working point. But still getting a 'Device not recognized' warning every few minutes, and still don't have a working mouse. I don't want to have to do system restores back to pprevious dates, although I suspect this is one solution.

Hello,
I just wanted to let u know, I had this same issue for about 2 weeks. Basically what happened was a bad install of my AMD Chipset drivers. When I attempted to upgrade, the install didn't go all the way through.
I then restarted my system, and BAM! No Mouse or Keyboard functionality thru USB.
Even when I went into SAFE MODE the Mouse and Keyboard were not functional. The only time they worked was when the computer first attempted to start, BEFORE windows loaded.
So, this means that your issue is a software problem.
I thought it was some other software that I installed, and ran a restore session, but that wasn't the issue. Still no functionality.
I even tried removing my CMOS battery, to reset it, since some people said that had solved their problems...Still nothing.
I then read other forums around the web using my Android phone to try and find a solution, only those solutions were no help.
I was also advised to run: MSCONFIG and Hide all Windows programs and then stop every other driver, source from loading (of course if my mouse and kb worked, I would have tried that).
I had even read that because I was using USB, that I should try using a PS/2 Mouse and Keyboard connection.
It took me 2 weeks to get the correct PS2 adapter that worked, which would essentially allow me access to my system again...
I Purchased a USB A Female to PS2 (MDIN6) Male Adapter (for Mouse) from http://www.SFCable.com
This my friends, was a lifesaver. I only have one PS2 port on my system, so I used my mouse to try every option I had previously read about. Of course you cannot type because the keyboard doesn't work, so you need to know the location of the folder where
the programs you are trying to run are.
So, a little after I got back into my system, and I closed down all programs, the warning screen came up that ALL of my USB Ports failed and could not be updated. I even Uninstalled every last USB port from the System Properties and restarted, and still
that didn't work.
I had forgotten that during the time when this problem arose, there was a failed install of my AMD chipset drivers, so luckily I had not deleted the source file and I tried to reinstall, and VIOLA! I'm back up and running and my USB ports are restored
and everything is working!
I hope this solution is able to help other people out there.
Thanks,

USB Device Not Recognized issues

I have a Qosmio X505-Q860 and I've been getting the 'USB Device Not Recognized' error constantly for several months. I've never plugged anything into any of my USBs and the error is now causing a nice Blue Screen (which happened about 4 times yesterday within 1 hour). I've tried uninstalling the problem USB hub but it keeps telling me that it failed to uninstall (I'm on my administrator account when doing this). How in the world do I get rid of this so my computer stops crashing and driving me crazy!?
Edit: I should also mention that everything is up to date (I check often and checked just now).
"A stopped clock is still right twice a day."

I suggest trying another USB cable. If you are positive that your cable is not the issue then try resetting the iPod and booting into disk mode (Hold menu+select down until Apple logo appears. Then hold menu+play/pause down and the iPod will go into disk mode, see if the computer recognizes it then. If that works then their is either a software issue on the computer or a firmware issue. Worth trying to restore but backup all your iPod's files first!

"USB Device Not Recognized" Bubble/ Ipod won't connect to Windows

Whenever i connect my ipod to my computer the ipod goes to "do not disconnect" and a bubble pops up on my computer saying "USB DEvice Not Recognized" i have switched it to all of my usb ports and unplugged all usbs except for my mouse at the same time. this happens 95% of the time. my ipod does charge while connected and it has only connected to itunes once in the past 2 weeks. im not sure if it is itunes because it started around the time i updated to itunes 7. since it is a windows bubble though i think it is a windows or ipod problem and not itunes. i have a dell that isnt great but works fine.
thanks for any help.
... Go TTU!

Make that two idiots. My roommate got a Sansa and I decided to try out the cable. Nothing happened. Now suddenly my nano isn't recognized by my computer. I'm glad I read your post, now I can stop looking high and low for a solution. Until this happened it worked good as new.

"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

IPod nano 3rd Gen 8G "Device Not Recognized" on 2 diffrent computers...

I have the latest versions of iTunes on both a Windows XP service pack 3 computer and Windows 7 Laptop. I've tried multiple cords but both computers tell me "device not recognized", I've uninstalled and reinstalled all drivers. Done a reset and Disk Mode reset on my iPod. Haven't droped it or damaged it in anyway since i've connected it sucessfully to my computer last time. Will charge on a wall charger, car charger and dock. Tried connecting friends iTouch and it was registered by Both computers.
And ideas on a fix other than the $100+ apple wants, I'll just got buy a new MP3.

- Try another cable
- Inspect the dock connector on the iPod for bent or missing contacts, foreign material, corroded contacts, broken, missing or cracked plastic.
