Good job, but there are some warnings from MSVC v16 when I'm
using '-Wp64' in my CFLAGS. "enable 64 bit porting warnings".
I'm on a 32-bit WIndows:
libusb/core.c(692) : warning C4267: '=' : conversion from 'size_t' to
'ssize_t', possible loss of data
libusb/os/windows_usb.c(173) : warning C4267: '=' : conversion from 'size_t' to
'ssize_t', possible loss of data
I'm not sure these matters.
Also (maybe more serious). If I build a debug-version with '-RTCc'
("Convert to smaller type checks"), line 1117 in libusb/os/windows_usb.c
triggers a runtime-check since the line:
priv->depth = parent_priv->depth + 1
could possibly overflow (acording to the compiler at least).
This patch fixed it. But again, I'm not sure it matters:
