Universal Serial Bus (USB) provides a serial bus standard for connecting a wide variety of devices, including computers, 

cell phones, game consoles, PDA’s, etc.

USB Library contains HID routines that support HID class devices, and also the generic routines that can be used with 

vendor specified drivers.

USB HID Class

The HID class consists primarily of devices that are used by humans to control the operation of computer systems. 

Typical examples of HID class devices include :

 

- Keyboards and pointing devices, for example: standard mouse devices, trackballs, and joysticks. 

 

- Front-panel controls, for example: knobs, switches, buttons, and sliders. 

 

- Controls that might be found on devices such as telephones, VCR remote controls, games or simulation  

 

  devices, for example: data gloves, throttles, steering wheels, and rudder pedals. 

 

- Devices that may not require human interaction but provide data in a similar format to HID class devices,  

                 for example, bar-code readers, thermometers, or voltmeters. 

Many typical HID class devices include indicators, specialized displays, audio feedback, and force or tactile feedback. 

Therefore, the HID class definition includes support for various types of output directed to the end user.

Each project based on the USB library should include a descriptor source file which contains vendor id and name, 

product  id  and  name,  report  length,  and  other  relevant  information. To  create  a  descriptor  file,  use  the  integrated 

USB HID terminal of mikroBasic PRO for dsPIC30/33 and PIC24 (

Tools › USB HID Terminal). The default name for 

descriptor file is 

USBdsc.mbas

, but you may rename it.
