    I did exactly as you instructed and the same thing happens as I have described earlier when I plug in my USB flash drive.



    Any other suggestions?



    Thanks,

    Mark

    I have tried all that you have suggested and have not found any exclaimation marks in the control panel. I think I am going to scrap the flashdrive.



    Thanks anyway,

    Mark

Seems to be your problem.

Try this from MS. It's targeted for PC Card problems, but describes yours perfectly anyway:

1. Click Start, point to Settings, click Control Panel, and then double-click System (if the System icon is not displayed in Control Panel, click the View all Control Panel icons link on the left side of Control Panel).
2. On the Device Manager tab, click the plus sign (+) next to Universal Serial Bus Controllers.
3. Click USB Host Controller, and then click the Properties button.
4. On the Resources tab, click to clear the Use Automatic Settings check box.
5. Choose a basic configuration from the list that does not cause device(s) to appear in the Conflicting Device List, and then click OK.
6. You may receive a warning message that indicates that Plug and Play functionality is limited by forcing a specific configuration. Click Yes to continue.
7. Click Close.
8. Restart your computer.

It seems the reason is that when you plug the drive in, the IRQ's of devices are 'rebalanced', causing the crash.

This can be a problem with the USB port of that computer, try first connecting it on a different USB port of that computer so we can also check if this is a problem with that particular port only, and if its still having the same problem we now need to check the USB port of your computer under device manager... Under device manager check for the USB device and see if there's any exclamation mark if there is you right click it and select update driver and follow the wizard to do a online search for updated driver....

The first thing to try is to power down the PC and remove the USB key. Then disconnect the mains lead for 15mins or so. (with a laptop remove the battery.) Restart the PC and test. If this does not solve the problem then proceed as follows:

Start by unplugging all your USB devices, then use Add/Remove Programs in Control Panel to uninstall any USB driver software (printers scanners etc.). Next, boot up into safe mode(prees F8 just before Windows begins to load) and go to Device Manager (MyComputer- properties - Device Manager). When you are in Device Manager make sure 'Show hidden devices' is checked under the View menu. Uninstall all device entries in this as so;

1. USB peripheral devices (printers etc.)

2. HID and/or Composite USB (Human Interface Devices) You're using PS/2 input devices so you may not have this entry.

3. USB Root Hub(s)

4. USB Host Controller(s) (Universal or Enhanced Host Controllers)

You can then boot back into Windows (not safe mode) and it should populate the Root Hubs & Host controllers again. Plug your USB devices back in. Be aware that most USB printers and scanners need to have their drivers installed first before you plug them in. Last, try your USB key.

Let me know how you get on!

It will only show USB devices that have been formatted. Have you tried going into the Computer Management, Disk Management to see if the usb drive is recognized? Can another windows PC recognize the USB drive?

Hello - computer recognizes the Cruzer sandisk however it won't open or run LaunchU3.


If you are using Windows.
Open the Windows explorer.
Plug the device in a USB port and wait for the computer to recognize it. After it is recognized the Windows Explorer will show two additional icons, one of them a CD-ROM.

Click the icon with the CD-ROM, and it will execute the U3 operating system. A small yellow icon with a U3 label will appear on the task bar. Right-click the icon on task bar and select the "Open U3 Launchpad". Point to the Settings button on the right side.
Right click that button and select the U3 LaunchPad settings

In the window that pop up point to "Autorun" button and click it.

Click the button that will say Enable.
After that it will launch automatically whenever the device is recognized by a computer.

If the U3 launchPad is missing from the device you can download it from the SanDisk site. Here is the link. Download it and install it on your computer. Note:It does not launch on MacProducts or Linux.

How do you use a flash drive on the computar


Hello

Install the USB Flash Drive:
Plug the USB flash drive into a free USB port on your laptop (it is an approximately 1/2" slot, either on the side or back of the laptop).
Windows XP operating system should recognize it. It may ask you what you want to do with it. Select "Open folder to view files using Windows Explorer" and click OK.
Operating system should assign it a drive letter (see the title of the Windows Explorer window that opens).

Use the USB Flash Drive:
In Windows Explorer, click Folders button on the menu bar to show the installed drives on the left pane of the screen.
To copy a file from c:\ (hard drive) to flash drive:
Find the file you wish to copy on the c:\ drive.
Right-click it and select Copy.
Right-click the location on the new drive where you wish to paste the file, and select Paste.
(File should now appear in desired location.)

Hope you find this useful, if you have any more questions, just leave a comment and i will get back to you as soon as possible.

Kind regards
Andrea

Computer is not recognising the flash drive


Do other computers read the flash drive? If not, faulty drive. If yes, it may be recognized but you have Auto-play disabled. That's actually a good thing. Assuming this is a Windows computer that is at least XP or newer, open Windows Explorer (not Internet Explorer) BEFORE connecting the USB drive. Then left-click on the My Computer item. The right side of the screen will display all currently recognized drives. Plug in the USB drive and watch the righ side of the screen. I'll bet a new drive will appear within about 45 seconds. If so, just double click on the new drive and you'll see all your "stuff". If not, you may have a faulty USB port.
