The BT Mighty Mouse is the only BT device being used in the household so at least my problem isn't BT interference from other BT devices.
It is extremely unlikely that BT devices would interfere with each other. BT radios are by design limited to very low power & short range. They share a part of the radio spectrum with an increasing number of other services, most of which use higher power to achieve greater range. That would make them very unreliable except for the fact that BT devices slice up this shared part of the radio spectrum into thousands of very narrow channels & "hop" from one channel to another over a thousand times a second. Thus, they are usually able to find little bits of the radio spectrum that no other service or BT device is using frequently enough that communication appears continuous. This is possible in part because BT is a comparatively low data bandwidth service & these narrow little channels are still wide enough to support its modest data rate.
Since BT & the other services use radios carefully designed to transmit only over their assigned channels (whatever the service's assigned width or power) even if they malfunction, interference among them is rare. The problems come largely from devices not intentionally designed to broadcast radio signals that can malfunction & emit relatively high power broadband noise signals that knock out wide parts of the spectrum at once. This principle is used intentionally in military jammers; here it is an unintended consequence of poor design (like with some "home brew" PC's).
