The way I know it's been done successfully is by using this DLL:
http://www.kadtronix.com/usbhidapi.htm
Unfortunately it's not free (it costs $39) but I'm reliably informed it makes the task very easy.
In principle you can probably do it directly from BB4W code, but I'm not aware of anybody having achieved it.
Richard.

I have seen VB declaration:
Public Declare Function SI_Open Lib "SiUSBXp.dll" (ByVal dwDevice As UInt32, ByRef cyHandle As UInt32) As Integer
I can use BBC to read serial real time information along COM1...COM19 (thanks to many examples, advices by Richard in many discussions and manuals etc.) However, I am unable to read and write in my BBC4w program any information that moves in or out via my PC's USB port
That Siusbxp.dll ,I have in my pc now. How to change that VB statement into suitable format in BBC4w?

Code: SYS "LoadLibrary", "SiUSBXp.dll" TO siusbxp%
SYS "GetProcAddress", siusbxp%, "SI_Open" TO SI_Open
Alternatively you can use Jon Ripley's LoadDLL library to do the same thing more neatly:
Code: SI_Open = FN_LoadDLL("SiUSBXp.dll","SI_Open")
In either case you would call the function as follows:
Code: SYS SI_Open, dwDevice%, ^cyHandle% TO result%

This another finding from internet below is more complicated. How could this be written in BBC Basic?
Private Declare Function SI_Write Lib "SiUSBXp.dll" (ByVal handle As Long, ByVal Buffer As Long, ByVal NumBytesToWrite As Long, ByRef NumBytesWritten As Long) As Long
So I am trying to use an usb port instead of classical COM1 that was opened for random binary input output
19200, 8,N,1 . Silicon Labs driver

To call that function in BBC BASIC you would do:
Code:SYS SI_Write, handle%, Buffer%, NumBytesToWrite%, ^NumBytesWritten% TO result%
(having previously set Buffer% to point to the data to be written).

The CP210x USB to UART Bridge Virtual COM Port (VCP) drivers are required for device operation as a Virtual COM Port to facilitate host communication with CP210x products. The command like this
port% = OPENUP("COM3: baud=19200 parity=N data=8 stop=1")
works well then if a serial equipment is pushed into an USB 'hole' in a PC.
In my Xp there must be found then- under device manager /system- COM & LPT port a following driver:
Silicon Labs CP210X USB Uart Bridge (COM 3)
My question is how to put/call into a BBC Basic program that Silicon labs driver?
cp2010x. manufacturing.dll such that the user has no need to install him/herself the driver under his/her system?
