This would keep the device from reprobing all the time. : : Good idea, I'll make that change tonight. The code I committed this : morning returns ENXIO for them so probe will get called multiple times. : Hmm, this may be more difficult than I first thought since some of the : internal routines walk all devices in the devclass, operating on their : resources. This change would require that code to have an extra case, : "device here but not active". Right now it assumes that if the device is : probed/attached, it is usable. The device is already there. All the device_disable() would do would keep it from being probed again. Warner
