Hi.
If I open a ftdi device in an instance of our application it seems not
to be claimed for exclusive access. A second instance of the application
can "steal" the device later.
I found in the sources of libftdi that the libusb function
usb_claim_interface() is called correctly by ftdi_usb_open_dev(). It was
my understanding that usb_claim_interface() marks the device to be "in
use" and a second call would result in an appropriate error.
Under windows this is not an issue. The device can be claimed only once.
I would very much appreciate if you could help me to figure out what is
wrong here.
Regards, Thomas
