the default context. Previously NULL would be passed for the default context,

|
still get passed NULL

OpenBSD 5.3-current or later. Users of older OpenBSD versions are advised

|
to stay with the libusb shipped with OpenBSD (mpi)

APPENDIX A - How to maintain code compatibility with versions of libusb and
|
|
libusb that use MaxPower:
|
|
|
|
If you must to maintain compatibility with versions of the library that aren't
|
|
using the bMaxPower attribute in struct libusb_config_descriptor, the
|
|
recommended way is to use the new LIBUSB_API_VERSION macro with an #ifdef.
|
|
For instance, if your code was written as follows:
|
|
|
|
if (dev->config[0].MaxPower < 250)
|
|
|
|
Then you should modify it to have:
|
|
|
|
#if defined(LIBUSB_API_VERSION) && (LIBUSB_API_VERSION >= 0x01000100)
|
|
if (dev->config[0].bMaxPower < 250)
|
|
#else
|
|
if (dev->config[0].MaxPower < 250)
|
|
#endif
|
