[libhid-discuss] check if the device is still connected?

[Gabriel Rossetti]

Hello everyone,

is there a way to check if the device is still present?

hid_find_usb_device() can't be used if the device is open and I'm not sure
hid_is_opened() detects if the device was opened and then unplugged
correctly.

Thanks,
Gabriel

What happens exactly when a device is unplugged? Am I responsible for
cleaning
anything up (e.g. do I have to close it, release the interface, etc)?
