GEOM should pick up the state change, but the bug may continue to exist because the CF reader is tagged as a storage device with invalid media when umass attaches to it on startup; there wasn't a really good way to actually enumerate the slice table upon insertion because the device does not send a disconnect/reconnect to the bus when you insert the card. At the time, the workaround was to tickle the device by attempting a mount against the whole disk, then the slice table will be enumerated.
Example, CF card reader on boot will be picked up as /dev/da4 You insert card, no state change can be detected because the device doesn't get reset on the bus. mount /dev/da0 /mnt <-- will fail for obvious reasons, but now slices are enumerated mount /dev/da0s1f /mnt/mycfcard <-- ok On 2009-07-23 06:24:17PM +0300, Andriy Gapon wrote: > on 23/07/2009 17:14 Kevin Oberman said the following: > > If Linux detects media insertion instantly or Windows detects media > > insertion instantly (which I can confirm), there is some signal > > available, so looking at the Linux driver should provide a clue as to > > what to look for and that can be added to the FreeBSD umass driver.
