As of 1 November 2008, the total number of drivers stood at 68 in OpenBSD 4.4; growing by 7 drivers in a 6-month release cycle. This rate of growth, of one new driver per month on average, has been common throughout the history of the framework since OpenBSD 3.9.

As of 23 December 2006, the framework was used by 44 devices drivers. At this time, a patchset was committed converting a simple one-level addressing scheme into a more stable multi-layer addressing.

Framework use by the device drivers rose sharply with the release of OpenBSD 3.9. Then, in only 6 months, the number of individual drivers using the framework rose from 9 in OpenBSD 3.8 (released
