Description Arenas Belon, Carlo Marcelo 2001-04-04 17:34:31 EDT

when autoplug is executed to load a module on the kernel because of a
hardware event (a device is connected), it doesn't check back to unload de
module when the device is disconected.

as the usb device is no longer connected, quering information such
(cdrecord -scanbus), returns errating messages from an already existing
scsi device that no longer belongs to a device.

this has been tested on qa0328 and kernel 2.4.2-0.1.40.

Comment 1 Pete Zaitcev 2002-06-03 14:07:09 EDT

I am afraid this is WONTFIX material.
We found that doing the "rmmod -a from cron" trick is
very harmful (it removes usb-uhci, for instance).
Upstream community says the same.

It should be possible for sd to figure that the device
is offline (by check condition status from usb-storage).
If it does not work, I can consider an RFE.
