| 2012-09-26: v1.0.14 | |
| * Reverts the previous API change with regards to bMaxPower. | |
| If this doesn't matter to you, you are encouraged to keep using v1.0.13, | |
| as it will use the same attribute as v2.0, to be released soon. | |

| 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 |
