bool "Comedi USB drivers"
depends on USB
---help---
- Enable comedi USB drivers to be built
-
- Note that the answer to this question won't directly affect the
- kernel: saying N will just cause the configurator to skip all
- the questions about USB comedi drivers.
+ Enable support for comedi USB drivers.
