I have tested and installed multiple Zunes on different PCs, Laptops, and other devices. And have not run into this problem as of yet. And there can be a number of reasons why the device does not install properly.
DEVICE PROBLEMS:
To troubleshoot you will have to do a hard reset and erasing everything from the Zune player. On the PC you wish to install hopefully you dont have conflicts with other WPD "Windows Portable Device" architectures such as PDAs, cameras, some bluetooth devices, and even cellular syncing software like Motorola Phone Tools (for example). Motorola USB controllers work fine, already tested.
FIRMWARE \ SOFTWARE:
Here is a list of most of what is installed for Zune, Zune Bus Enumeration (Wireless Syncing), and Windows Portable Device controls and their locations: Check to see which files are in the right place and which are missing.

EDITING THE REGISTRY AT YOUR OWN RISK:
For each Zune device a new device set is installed in the registry under Local Machine - HKLM\System\Enum\CurrentControlSet\USB\Vid_045e&Pid_0710
Make sure in these keys exist in the registry, under that key will be additional folders for each device.
Delete the sub folders, download the Zune 2 software from the site.
Restart and re-install.
