USB mass storage driver?

Ok, so I went out and got an iPod nano. I had it for about 5 months, and now
all of a sudden it just doesn't connect to my computer anymore. The computer
does not recognize the device, thus making it impossible to put new songs
onto my iPod. I go onto google, and look up some iPod forums ( and try apples
site, but they were basically useless ) and from what i understand, i am
missing my USB mass storage driver ( the drive used for iPods, is what i'm
guessing). I have no idea where to find this or how to find it. I tried
google, but who knows what is safe anymore on free downloads. Is there any
downloads on the microsoft site for this driver, or am I going to have to
wait like a month till my moms friend can fix the computer?


P.S - here are my comps specs incase you need the info

Processor: 2.53 GHz Intel Pentium 4
Number of Processors: 1
RAM: 512 MB
RAM Type: SDRAM
Hard Drive: 120 GB
CD-RW: 40x (read), 10x (write), 40x (rewrite)
DVD-ROM: 16x
Operating System: Windows XP Home Edition

Hello,

To rule out that your iPod may not be the problem, try connecting to another
computer and see if it works.

Install the driver (iTunes) for your ipod from here. If you already have it,
try uninstalling and reinstalling it back.

I have tried re-installing and stuff for itunes. and i have also tried my
ipod on another comp..and my bro's ipod ( he only had it for 1month, and it
enever leaves his room so it's like brand new ) doesn't work either

So when you try your ipod in another computer, it works?

If not, the ipod is faulty,

Otherwise, sorry, I am out of ideas.

Maybe try a different USB port if you haven't yet. I had trouble with mine
if I plugged into the port on the front of my computer. If I plugged into
one on the back of the computer it worked fine.

Problem:
Windows XP does not recognize USB Mass Storage Devices
Device is detected and listed with an exclaimation mark in Device Manager

Solution:
After spending hours on internet and reading through numerous posts, I found following solutions which will definately work:

1. Delete following file: windows\inf\infcache.1

2. Go to windows\inf folder and see if you have read/write permissions for following files:
usbstor.inf
usbstor.pnf
If not, open security settings for above files and add your username for read/write access.

3. Open registry editor and:
Delete following keys:
HKLM\System\CurrentControlSet\Enum\USB\ <read all keys and delete all those saying USB Mass Storage Driver>

Add following key:
HKLM\Local_Machine\CurrentControlSet\Services\Usb
Add a new DWoRD Value and name it "DisableSelectiveSuspend". Give it value 1

4. Make sure you have USBSTOR.SYS file in your windows\system32\drivers folder (It wasn't there in my case). Just Google using Usbstor.sys and you will find the file to download. Save it at above location.

After doing above steps, restart your PC. Now Windows should recognize your mass storage and should do an autoplay.

5. Some posts also mention that turning off the system and pulling out mains power supply and batteries for 30 mins is also helpful to resolve above problem.

In case you face any problem in completing above steps (need detailed info) simply drop a mail at prashantisonline@yahoo.com. I will be glad to assist as I can feel the pain of this wierd problem.

Believe it or not, some small USB mass storage devices can only communicate over a short USB cable. Regardless of the USB standards, I have confirmed this several times with external drives from WD and others.

The cable that comes with the USB drive is generally about a foot. I have had numerous users that hate the short cable and use a longe cable instead. Then they call me and complain that the USB drive has a power light and is detected as a Mass Storage Device, but the drivers will not install. I replace the long cable with the original short cable, and tell them they owe me lunch. Worth a try, sometimes they actually do buy me lunch.

Doesn't seem to be my problem. Drivers are installed, device said to
be working properly, uninstalling and then running "new hardware"
reinstalls apparently satisfactorily. I'm just about to remove 500
gig HDD and replace it with an 80 to ensure enclosure is working.

Hello, I have similar problem.
I have PQI 8GB Traveling disk U273 and it worked OK 2 years. I had inserted it in one PC that often change USB devices (BT, flash disk, Samsung phone) and after inserting my USB, windows detected Unknown device. (File system was NTFS). After that on any other PC, 8GB flash not working...
In Linux Ubuntu, I can format usb flash in fat16, fat32, ntfs, ext2/3/4, but usb can be used in fat16/32 format, as 1 or 2 partitions disk, but in ntfs format disk is read-only! and any format is still undetectable in windows xp/7.
