Re: USB device not recognized

Manga, I have the same problem with my Sandisk Titanium Mini Cruzer 4GB just 4 days ago. It worked well in all 5 different computers which I use on a regular basis then 4 days ago, I got the same error message you got with yours: "USB device not recognized" and the blue light turns off after 1 or 2 seconds just like yours. I called sandisk and spoke with 2 different techs and all told me what MARKEVANS posting advised..."its corrupted, get a new one."

For me getting a new one is of course easy it's the data that is so important as I have lost data that can cost me thousands. Out of desperation, I called a data recovery group to try to recover data...this option is costly as well ($500-1000). So out of sheer desperation just today, I plugged the Cruzer into one of the computer at work which has a USB hub. I was amazed to find that on the hub, IT WORKED. I immediately transfered all the data to the hard drive. None of the data was lost. Out of curiosity, I pulled out this hub and plugged it into the computer that didnt work and sure enough, the cruzer drive was recognized once again. I still don't know why using the hub works but sounds like a circuitry problem. Of course I will get a replacement but if data is important to you, you might want to try this with a USB hub and see if it works for you.

Good luck

Re: USB device not recognized

not fixable.
device can not tell os what it is. that is the most basic of functions.
without id, it can not set configuration needed to access data.
probably already lost data anyway.
replace is about the only option.

sorry for the news
good luck

Windows does not recognize the device ?

Hello raigangarkam,

There's a chance that that particular USB slot on your computer may not be working.

You may try to attach another USB device on that port to check if that works or not.

You might also want to try & attach your 2GB Cruzer flash drive on another USB port or another computer & check if it recognizes it.

If it still won't be recognized on the other computer, you might need to replace that 2GB Cruzer USB Flash Drive.

Hope this helps.

My U3 Smart SanDisk Cruzer Micro 2.0GB USB Drive Not Recognized

We can fix it -- and recover the data (provided it is recoverable -- which it generally is). If we don't get your data back, we ship the drive back to you and you pay nothing. We've been recovering data for over 16 years and are successful about 85% of the time.

Cannot get my USB memory stick to install on XP

I have a sandisk cruzer, titanium 512mb. Model: SDCZ3 512 I have used this to store massive amounts of data that I frequently need to access. Recently, when I plugged the device into my computer's USB, I received the following message: "USB Device Not Recognized" After double clicking on this message, I got the USB Root Hub. The last item on the tree stated: "Unknown Device." I double-clicked on the unknown device, and in the Device Status box, received the following message: "No Drivers installed for this device. If you are having problems with this device, click Troubleshoot to start the troubleshooter." I attempted to troubleshoot, but the device remains unrecognized. How can I access the data I have stored on this device? I have even tried to install the drivers automatically, but it would not istall succesfully.

Not recognized by USB

go to my documents and select the removable disk drive usually f:, if that does not work switch between a drive and c drive. Usually it takes a second for the computer to realize that the USB drive is being used and for it to be read. Let me know how it goes and if you need other troubleshooting tools.

Cruzer Scandisk 2.0 titanium

Hi, Not unless you are using Windows98, your PC should automatically recognize the SanDisk Cruzer Titanium as a "Removable Storage/Device". Driver is not required for Windows ME, W2k or XP. If for some reason the SanDisk Cruzer Titanium (non-U3 devices) is not recognizable, then perhaps it is not a problem with the PC but with the SanDisk. Pls try all other USB ports of your PC (front and back). The SanDisk website provides utilities/software for this kind of eventuality. They are Sansa Firmware Updater and Sansa Connect Recovery Tool. Both are available at Pls be forwarned that some utilities can and will reset your SanDisk to default and any or all data can and may be deleted. Hope this be of some help/idea. Pls post back how things are or should you need additional information. Good luck and kind regards.
