I noticed a memory leak after updating to libusb 1.0.16 which added hotplug
support, the leak is also present in the current git version. Basically I see
libusb_device object leaking and tracked this down an unhandled hotplug left
event that was created between my last call to
The default case in windows_transfer_callback() calls windows_error_str(0)
which will convert the error code returned by GetLastError() to a string.
This currently works because windows_transfer_callback() is either called
with io_result set to NO_ERROR or io_result set to GetLastError().
If
cb_response_in was called. But
as you don't neither of this the transfer_response_in object leaks.

thread always exits correctly and that you are not starting a new hotplug
thread before the old one has ended. And this is where the problems are:
In the error path of windows_init you're just terminated the hotplug
The sessionID value is 64-bit, so print it as 64-bit value and don#39;t
truncate it to 32-bit.

I also noticed that the 64-bit sessionID gets stored in the unsigned long
session_data parameter of the libusb_device struct. First I thought this would
be a problem because the 64-bit value could get truncated, but as recent Macs
are all 64-bit and LP64 is in place there, unsigned long is also
Yes, these two patches fix the problem, thanks.
