Libusb hotplug removed and crash on close bug solved. #129

Closed cristi-iacob closed 5 years ago

cristi-iacob commented 5 years ago

In this version, we have changed the hotplug mechanism from libsmu. This is because in the last versions of libusb, they have changed the way it works. On the latest versions, when a hotplug signal is emitted (and the callback is started), the device becomes busy, until the callback ends. This thing makes the hotplug mechanism from libsmu inoperative, because it is (almost) impossible to synchronize the callback end time and libsmu calls on the device. When this branch will be merged into master, we will not use the old version of libusb anymore and will use the latest available libusb version (link to the libusb github repository: https://github.com/libusb/libusb).

Therefore we have removed the hotplug_attach and hotplug_detach methods from libsmu and the "-p, --hotplug-devices" option from the API.

In order to show how the hotplug mechanism works, we have modified the hotplug example as well, giving a possible method for simulating the hotplug process.
