This library is intended to make non composite USB devices:

HID: Human Interface devices, e.g. Keyboard, mouse, etc..

CDC: Communication device: e.g. serial port

MSD: mass storage device, e.g. SDMMC card.

• HID
  USB "HID" library. Creates a non composite USB HID device. Permits to read data from and write data to USB devices using the "HID" protocol (no driver at PC side required).
   
• CDC
  USB "CDC" library. Creates a non composite USB CDC device. Permits to read data from and write data to USB devices using the CDC protocol (makes the USB device look like a serial port).
  2010-03-01: Capable of working with usbser.sys under windows (means Hyperterminal can be used), and also works under Linux (Thanks Rainer!).
  
  PP2 = PingPong version of the library.
  
  Important CDC remarks:
• - You need the UsbSer.sys driver (to be present in C:\Windows\System32\drivers) and the UsbSer.inf (to be present in C:\Windows\inf) file. Both can be found here https://libstock.mikroe.com/projects/download/71/9650/1525280064_usb_oa_other_other.zip in case they are missing.
• - Do not forget to add (if not already there) the VID and the PID of your device to the usbser.inf file (C:\Windows\inf).
• - Every time you install (plug in) a CDC device with a new VID/PID combination, windows will give it a comportnumber that was not used before, so the used number always increases. If you want you can change it to a more acceptable number using the windows 'device manager'. Portnumbers already taken can be found in the registry: See https://libstock.mikroe.com/projects/download/71/9649/1525279626_usb_oa_other_other.zip.
•  
• MSD
  USB "MSD" library. Creates a non composite USB MSD device. Makes the PIC (equipped with an SD/MMC card) look like an external drive to the PC (no driver at PC side required). 
  
  Important MSD remarks:
• The library assumes the SDMMC card is always present and writable. Also hot swap is not allowed.
• The maximum cardsize supported is 4 GB.

USB keyboard library: Supports also the "Sleep", "Wake-up" and "Power" keys.

Libraries:

- USB_HID_Library

- USB_CDC_Library

- USB_CDC_PP2_Library

- USB_CDC_Library_P18FxxJ53

- USB_CDC_PP2_Library_P18FxxJ53

- USB_MSD_Library

- USB_HID_Keyb_Library

Have fun!

-------------------------------------------------------------------------------------------------------------------------------------------------

Version 1.1: Changed so that PID and VID defined in the "Usb_xxx_ProjectItems" projectfile effectively show in the executable when the libraries are used without sourcefile.

-------------------------------------------------------------------------------------------------------------------------------------------------
18-03-2012: Removed an error in "USB_MSD_Library", calculation of the card capacity did not work correctly for cards of exactly 4 GB. The max card size supported stays 4 GB however.

------------------------------------------------------------------------------------------------------------------------------------------------
20-03-2012: The USB HID, CDC and MSD libraries for PIC24 have been added. No PingPong or Keyboard library however.

2012-06-08: The help section in the package and zip file has been updated.

------------------------------------------------------------------------------------------------------------------------------------------------
2012-11-12: The microBasic package(s) ha(s)(ve) been added.

Only the .mcl files are available as "library" files: they are copied from the mikroPascal version (the mP and mB .mcl files are compatible - luckely - ).

If you want to see some sources: look into the mP versions.

The example files are still in mP, not in mB. (I do not have an mB licence, so I can not compile them).

Some of the helpfiles are also still referring to mP, but all library "interfaces" are available in the mB language.

------------------------------------------------------------------------------------------------------------------------------------------------
The "USB_CDC_OA" library has been updated, it is compiled with the SSA opn ON now (gave problems when using the lib with mB).

------------------------------------------------------------------------------------------------------------------------------------------------
2013-01-26:  Replaced "Delay_ms" and "Delay_us" by routines available in the Delays lib.
"Delay_ms" and "Delay_us" are inline routines and cannot be used in libraries if they are to be used without source (e.g. non Pascal compilers).

----------------------------------------------------------------------------------------------------------------------------------------

2014-03-13: The mikroBasic files and zip files have been updated. All mB sources are present now (not tested if compilable though).

---------------------------------------------------------------------------------------------------------------------------------------------

2014-03-26: Corrected an error in the Delphi unit "Wincom.pas" (used in the windows application TestCDC). Thanks to Virgil Chindris for pointing out type errors in the routines "getChar" and "OpenCom".

---------------------------------------------------------------------------------------------------------------------------------------------

2014-05-02: CDC library: Removed automatic sending of a zero length packet after sending a 64 bytes packet (slowed down sending  from PIC to PC).

---------------------------------------------------------------------------------------------------------------------------------------

2014-05-03: PIC version only. Added the following CDC libraries:

• USB_CDC_Twin_Library: creates 2 virtual COM devices on the PC
• USB_CDC_Library_P18FxxJ53: the same as USB_CDC_Library but specifically for the P18FxxJ53 family
• USB_CDC_PP2_Library_P18FxxJ53: same as above but with ping pong buffering.

2015-01-26: Replaced the mB files: all mB files are compilable now (which e.g. means that all "with" statements are dealt with). I could however not link and test the libraries (no mB licence).

------------------------------------------------------------------------------------------------------------------------------------

2016-08-14: Changed the HID libraries: the USB_HID_Write routine now actually writes the asked bytecount. This is important for devices sending less than 64 bytes.

2019-04-12:  Removed a blocking statement in 'InitUsb'. The SW was blocked in case no USB connection was made.
