Hi people,

Hi Hans,
I have recently read the thread and I am trying to get all the
information I can before digging more into the matter.
It is a complex matter and I just one to try every single possible
solution and be advised from the experts in the matter.
Thanks in advance,
Roberto
Hi,
In FreeBSD there is a special function that the application can use to
check if the USB device is still present: libusb_check_connected()
Checking this function regularly and then closing the USB handles might
fix the problem you are experiencing. At least for debugging, try to
print the value from this function in a separated thread, and check if
there are any differences when you experience the hang.
Try to use GDB to collect all backtraces for apps using the USB handle.
