Hi.
I need to write some user interface to perform some tasks with USB
storage devices. One of the tasks is to show a list of all USB
storage connected and all slices/partitions and filesystems in them.
With tools like usbdevs and sysctl, I can find out what USB devices
are connected, and also what USB drivers handle them (so I can see,
for example, that there is a SanDisk Cruzer Micro connected to port 2
in bus 3 and the umass driver under it).
I can also find out what da devices there are using camcontrol.
However, how can I find out which da device was assigned to which
umass/usb device? I see this info in some inconvenient form in
dmesg. But I need something easier to handle programmatically to
write a program that uses that data. I prefer not to resort to some
ugly hack like trying to parse dmesg.
Also, I'd be interested if it were possible to have my program
informed when devices are connected/disconnected. Can a process ask
usbd to send it some signal and somehow provide the details of the
event when a device is connected/disconnected?
Thanks,
-- Tom
