| |
| 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 |
