select FW_LOADER
---help---
This is a driver for the ZyDAS ZD1211/ZD1211B wireless
chip, present in many USB-wireless adapters.
Device firmware is required alongside this driver. You can download
the firmware distribution from http://sf.net/projects/zd1211/files/
config ZD1211RW_DEBUG
bool "ZyDAS ZD1211 debugging"
depends on ZD1211RW
---help---
ZD1211 debugging messages. Choosing Y will result in additional debug
messages being saved to your kernel logs, which may help debug any
problems.
