I have a 32 GB Lacie Cookey USB flash disk that doesn't show in the Computer window but it's visible as a device.
It also appears in the Disk Management tool, but the box is empty.
Is there anything I can do or is it dead?

Looking at the Chipgenius Dump, it is a Phison Controller.
You can try the following steps one by one and check if any of them helps:
- Download Rufus or Bootice and try formatting your USB drive in Windows.
- If above step does not help, connect the USB Drive to Linux Operating System and check if you can access the files. If you can, copy your files and format the drive in Linux using Gparted or Disk Utility.

If the above two don't help, then try this: download Phison Mass Production tools for your USB Drive from http://flashboot.ru/files/phison/ and try formatting your USB Drive. You will have to try with each tool until you succeed. This tool will try to reprogram your USB Drive's Microcontroller and format it again. NOTE - This will delete all the files in your USB Drive.
Check this link for a detailed guide on how to do this (in this guide the MPtool is being used to repair a fake USB Drive): http://agnipulse.com/2010/04/how-i-fixed-a-fake-64gb-usb-drive/
Look at these answers for details on Mass Production tools:Flipping the Removable Media bit -- alternatives to BootIt? and How to format/repair a write-protected USB drive with I/O errors?
Hope this helps. Let me know how it goes.
Do you have the proprietary driver software installed? This should be it: http://www.lacie.com/support/drivers/driver.htm?id=10253
Also, make sure Windows update isn't automatically replacing it with the default 'Mass Storage Device' driver.

When there is a “No Media” error message, it basically means that the USB flash drive isn’t in full contact with the USB socket. Sometimes the USB access/power light may come on even when there isn’t full contact on the two D+ and D- pins, or pin 2 and 3 of the A connector. Realterm serial terminal for samsung.
Try the drive in another USB socket, a USB hub, or use a USB extender cable. A USB extender cable usually lets you see if the 2 holes on the sides of the type A male connector mate completely with the 2 fingers on the female type A socket.
When the USB connector and socket mate completely the USB flash drive should appear.
