I'm trying to update my project which uses libusbx 1.0.12 to 1.0.14 but
I'm experiencing some problem which where not present before. For
instance in my application I'm discovering all the devices with a known
VID PID, opening them to read some more information and then closing
them again.
After discovering is done I try to open the device again but using the
latest version of libusbx I get LIBUSB_ERROR_ACCESS. It seams that the
close is not performed correctly. Below the trace log:
