Follow these steps to find the problem:

Make sure that you are connecting only a single device to your computer at a time. Do not have another calibre supported device like an iPhone/iPad etc. at the same time.
Make sure you are running the latest version of calibre. The latest version can always be downloaded from the calibre website
Ensure your operating system is seeing the device. That is, the device should be mounted as a disk that you can access using Windows explorer or whatever the file management program on your computer is.
If you are on Linux and the device is an MTP device, make sure it is not automounted by the OS/file manager as only one program can access an MTP device at a time.
On Linux, device might fail to mount if after updating kernel system wasn't rebooted.
In calibre, go to Preferences->Ignored Devices and check that your device is not being ignored
In calibre, go to Preferences->Plugins->Device Interface plugin and make sure the plugin for your device is enabled, the plugin icon next to it should be green when it is enabled.
If all the above steps fail, go to Preferences->Miscellaneous and click debug device detection with your device attached and post the output in this forum
