Usb device not recognised

Usually this thing occurs because of "Not safly removing the Hardware" (Cable, in your Case) or if the cable is just plugged-in and out frequently.
So try to Plug it properly, it shouldn't be loose.
And once this Unrecognition occurs, usually restarting your PC can solve the Problem.
Also check that your connecter and port isn't loose, that makes the cable to Connect/Disconnect.

make sure the software is unstalled via control panel, ad and remove programs, make sure there no mention of finepix now load the software first, then plus in the camera check the usb cable as well

1. Connect the USB cable to your computer.
2. Press and hold the button while plugging the other end of the USB cable into the YP-Z5.
3. When the display shows USB Connected, release the button.
4. The device is now in USB mode.
5. When through, you must safely remove the USB device. Note: To safely remove the USB device, right click the USB icon ( ) in the bottom right of your screen, and then click Safely Remove Hardware.
   

1. Upon disconnecting the device, it will return to MTP Mode.

Can you use a USB card reader? The canon software is great but it best used for using a method called tethering your camera (when you shoot directly from camera to hard drive)

first thing i would do would be to make sure you plug the cable first into the usb port with the camera off then turn on the camera, see if it is recognized by the computer. If not the next step is to check your usb driver to make sure it is working. Try some other usb device. If it is recognized then i would make sure you have seated the memory card properly in the camera as well as the cable. I know that sounds dumb but that little usb cable to the camera has to be well seated. You may have to update your driver for the usb port.

ok..you may have blown the drivers..you can find new lexmark drivers for your model and o/s here

Try it on different pc to make sure it's not the camera, if it works on different pc, uninstall all the usb drivers in device manager then reboot

** Problem Solved **

I found it wasn't the camera entirely to blame. I tried another USB cable on another pc, and although the camera was doing the same thing as my problem, the computer recognised the camera as new hardware, and asked me how to access the pictures. So I was able to get the pictures from the camera to the computer, and then saved them on to my Kingston flash drive. So taking the flash drive to my daily PC, I plugged in my flash drive via a USB extension lead, and discovered that would read either... alarm bells rang. So I unplugged the lead, and put the flash drive straight into the computer direct. The computer recognised it immediately. So plugging in the extension lead again, and the flash drive, it read this now. So I tried the camera, and it recognised it.

So I don't know exactly what the problem was, but it was solved... saved me a lot of running around and money ;)

First, let's get the obvious/simple things out of the way, just to be thorough :) :
Power off the PC, leave ten seconds, power on again then try it.

Have you tried it with another USB cable
Have you tried it on another USB port on the PC (if you've been using a front port, try a back one & vice-versa - they're often controlled by different chips).

Assuming none of those work, the most likely cause is a corrupted USB driver. To fix this:
* Make sure the camera's USB cable is not plugged into the PC.
* Uninstall the Olympus software (Camedia Master) if you have installed it.

Now delete the C5060 device as follows:

* Go to the Control Panel. Double click on System. Click on the Hardware tab and then click "Device manager".

* Go to the View menu and click "Show hidden devices".

*Scroll to the bottom of the device list and expand the USB list. You will see some USB Mass storage devices.

* Go through the list: double click on one, wait for its properties sheet to open and look at the Location. It will have something like:

Location 0 (C5060Z ).

Hit "Esc" to close the property sheet. If it was the right one, delete it (select it with the mouse and hit Delete). If it was the wrong one, proceed to the next one.

* Close Device manager.

* Reinstall the Olympus software if you are using it.

* Plug the camera's USB cable into the PC as usual. If all goes well, you'll get the "Found new hardware" message and it will proceed to reinstall the driver, following which all should be well.

So you know the cam is ok and the cable, so you will have to point to the usb port not being able to push enough power through the cable to the camera as it must take a higher voltage than the other cam. Make sure that the other cam software is uninstalled and you have done registry clean in case of conflicts and also try using a different usb port but install the camera with the driver again using the extension in it, aplogies if you did, i am assuming you may have installed the camera directly without the extension cable.
