The USB dongle that comes with the DiNovo Edge has a bug in its firmware. It crashes when the keyboard initiates the connection (when a key is pressed) and the connection is encrypted. If the host initiates the connection (when pairing) or the connection isn't encrypted (like in Windows XP), the dongle works okay.

There are two solutions to this problem:
 a. Buy another Bluetooth dongle without this problem
 b. Disable Bluetooth encryption
 c. Upgrade the dongle firmware (warning: this is dangerous).

My dongle has the firmware upgraded to version 2.1.238 and works flawlessly. The instructions to upgrade the firmware are here:
