Hello all,
I'm sure this is a bit of a newbie question. I have an app that is
receiving add/remove notifications for my USB device. It is possible
to have multiple devices plugged in at one time, and my app tries to
keep an updated list.
I am having a problem, because I don't see how to match a removed
device with the device that is already on the list. The io_service_t
value is different, and I cannot get a plug-in interface, presumably
because the device is already gone. I'm sure there must be a way to do
this that doesn't involve rescanning the bus and re-creating my list.
I can store any information that was available to the
IOUSBDeviceInterface that I received in the add notification. But I
can only match it to information that is available to the io_service_t
that I receive in the remove notification.
Can anyone help?
Thank you,
George
