  44. // complexity of the standards and poor writing quality in many

  45. // of those documents, remember descriptors are nothing more

  46. // than constant binary data that tells the USB host what the

  47. // device can do.  Computers will load drivers based on this data.

  49. // the descriptors.

  55. // only edited to add completely new USB interfaces or features.
