USB keydrive not recognised

i have a usb drive which cant be recognised on windows if i put a data while im on osx and opposide. does anybody know why its like that? thanks.

If you want a disk format that can be read both by a Macintosh and a Windows PC, basically the only option is formatting the drive in FAT32 (sometimes also referred to as "MS-DOS" format). FAT32, however, is not suitable as a format for the boot volume of your Mac computer. For Mac use, FAT32 is really rather limited and I recommend using it only on an external hard drive, which would then allow easy exchange of files between the platforms.
Cheers

Ipod not recognised by Windows, USB device not recognised

Hi hope someone can help
I have recently received my ipod back from Applecare who have sent the ipod back in ' working order ' but it will no longer be recognised by my windows. It says USB device not recognised and i cant find, nor will it install drivers that i located on the ipod updater etc.
I have tried several methods on this forum but none seem to work.
The letter from mycare says the iPod is formatted for a computer operating Mac OS X. Although i stated wi use Windows. But the leter states this can be changed bu installing the updater, but this wont make a diff as comp still wont regonise the device after i have followed there instructions. Any advice?
Thanks

I'm not really up on the complexities of the Windows OS but try this tip I picked up a while back, hopefully it might help.

Ipod "usb device not recognised" on one computer but works with another!

I have a 60GB ipod video and a 2GB ipod nano. Both connect fine to itunes on my work laptop but will not connect to my home laptop. They have previously worked fine with the home laptop but now when conected the message "usb device not recognised one of the usb devices connected to the computrt has malfunctioned".

If you have more then one USB port, try the other port.

Usb device not recognised by windows 7 on hp pavillion dv5094ea

Im having problems since ive updated my HP dv5094ea from windows xp up to windows 7,
Since the upgrade my usb ports arent functioning, i keep getting an error bubble saying
"Usb device not recognised" - device has malfunctioned
ive tried several trouble shooters including going into device manager and deleting the INFCACHE.1 with no luck, im starting to assume its a driver update issue...
can anyone help?

Hi:
W7 should have had the USB 2 drivers native to its driver database.
The only suggestion I can offer is to manually install the Vista graphics driver for your model which may have some motherboard drivers included.
Download and run the file below. You will probably get an unsupported operating system error.
http://h10025.www1.hp.com/ewfrf/wc/softwareDownloadIndex?softwareitem=ob-48969-1&cc=us&dlc=en&lc=en&...
Close out of any error windows. Go to the device manager. Click to expand the display adapters category.
Click on the display adapter listed there. Click on the driver tab. Click on Update Driver. Select the Browse my computer for driver software and browse to the driver folder that was created when you ran the file.
That folder will be located in C:\SWSetup\sp35203. Make sure the Include Subfolders box is checked and the driver should install.
After you reboot, see if the USB ports are working.

Usb device not recognised

hi i have a problem when plugging in my ipod touch, it says in a little speech bubble at the bottom corner "usb device not recognised, one of the usb devices attached to this computer has malfunctioned, and windows does not recognise it"
ive tryed everything, ive updated the driver, ive uninstalled the driver, and nothing comes up in itunes. the ipod does nothing when plugged in, it does not charge as well when plugged in. ived tryed in itunes the diagnostic test but when i click it it says "itunes has encountered a problem and needs to close"
please help me!!!!
thanks, calpol55

I am having the same problem. I went through all of the steps already listed (updating drivers, uninstalling drivers, uninstalling iTunes and all related software, reinstalling) and still no luck. I also tried syncing to a new computer, but am having the same problems. My Touch does at least charge when plugged into either computer, but is not recognized by either computer in iTunes to actually sync. The problem seemed to start after I updated iTunes on both computers, so I tried going back to the previous version of iTunes, but then I couldn't get iTunes to open because my library had been updated by a newer version of iTunes, so the old version wouldn't work anymore.
My Touch is not yet completely worthless since I can still charge and download apps and music straight to my Touch, but I can't organize anything very well and can't easily make new playlists or add new playlists from iTunes.

Libretto - USB Device Not Recognised error message

Hi there
I have a workaround for this problem which ocassionally happens. It is just to reconnect the USB hub(as recommended by Windows). I was just wondering if someone knows why this happens and how to fix it. The error is :--
"USB device not recognised. One of the USB devices attached to this computer has malfunctioned, and windows does not recognise it.
USB Roob Hub (2 ports) - Unused Port, Unknown Device.
Recommendation: try reconnecting the device. If Windows still does not recognise it, replace the device. "
I look forward to hearing back from you.
Kind regards
Julia.

Hello Julia
It is always advantageous to mention which model you have exactly. Obviously the external device is not recognized correctly. Check if there is some driver that must be installed before you can use it properly.

Same problem here, wondering if it has been caused by a recent OAD ?

Hi abbyntaff,
Welcome to Apple Support Communities!
Take a look at one of the articles below, the first iss for windows computers and the second is for Macs. They provide troubleshooting tips that should help resolve issues that would cause an iPhone to not be recognized by a computer.

USB Connection Not Recognised

Up until a recent upgrade to Windows XP, iPod Nano has been working fine.
The last few weeks I had intermittent success connecting often involving relodaing iPod or iTunes software.
Now nothing all i am getting when i connect the iPod is USB Device Not Recognised, I have tried all the USB ports, resetting, hard disk mode, obtaining the drivers usbstor which I found mentioned in another thread.
Is there something i have not tried?
I have followed the list in the Apple Tech Pages regarding the iPod not appearing in Windows or iTunes however this seems to be a problem ocurring before that step is even reached.
ideas?

Not sure if Time Zones are delaying any responses but I thought I'd add that I have just tried all the old favourites with my Laptop and I am getting the same deal.
Currently the iPod is working and playing music so is it possible my Cable is stuffed and needs replacing? has this happened to others?

Updater - ipod usb interface not recognised at PC

I have a a 15GB ipod with dock connector. It was working fine playing songs and was visible from my Windows XP PC via the single USB cable. I could see ipod files.
I downloaded ipod updater 2005-09-23 and selected update.
Thereafter :-
Ipod is no longer recognised by the PC, it gives - "usb device not recognised" when the menu button is pressed.
The ipod screen is blank. Reset gives the apple logo then the icon asking to connect the cable ( which is already connected).
Other usb interfaces on the PC give the same message.
Other devices connect OK to these USB interfaces.
The cable was working prior to the update.
Another PC ( compaq laptop ) gives the same "usb interface error message" when the ipod is connected.
the problem is within the ipod usb interface.
The updater appears to have corrupted/changed the ipod "usb interface"
I am unable to update again or restore as no connection available to the PC.
How can I restore the ipod's usb connectivity?

I went out and bought a firewire cable today.
The ipod was immediately recognised and ITUNES updated. I then connected the USB cable. It now works OK as well. I am so relieved.
On the updater screen, if you right click on the top bar, it drops down the "ipod models" updated by this version.
For my model it shows a firewire icon on the ipod. Is this co-incidence? I expect so.

USB device not recognised - comes up when I plug i-pod into PC

When I plug an ipod (have tried 2) into my PC I get the message
USB device not recognised
One of the USB devices connected to this computer has malfunctioned and Windows does not recognise it
I have tried several USB ports and 2 different connecting cables
Help!!
Thanks

Try to restart your computer?
If you have one of the newer iPod's it could mean the service pack is not up to date on Vista/XP
To check your service pack, right click on My Computer and click on Properties.
Vista should be service pack 2, and XP service pack 3
iTunes HAS to be updated to iTunes 10 or later
If it is not a new iPod, you could have to update your USB drivers
http://support.apple.com/kb/TS1538 follow that and it should work
If none of those resolve the issue, try uninstalling and reinstalling iTunes

USB Device Not recognised on XP Iphone 3G, but fine on win 7

I wonder if anyone can help me?
I plugged my Iphone 3G into my Work computer (win 7) yesterday and installed Itunes with no problems. I didn't sync or anything, I authorised my work computer as well.
I then went home and the second I plugged it in to me Dell d610 on Win XP is says USB device not recognised. I've looked at various forums and have unplugged and turned off laptop and then uninstalled USB root hubs but it will not work.
I then come into work today and find it works fine on my work Win 7 machine.
It's not the computer as I have 3 win xp machines at home and it's the same with all of them, 1 of them was patched a few days ago but the others havn't been patched since October.
I wonder if anyone knows what it could be?

If you have more then one USB port, try the other port.
