CONFIG USB

CONFIG USB

Top  Previous  Next

Action

Create settings related to USB.

 

 

Syntax

CONFIG USB = dev, Language= lang, Manufact= "man", Product="prod" , Serial="serial"

 

 

Remarks

Dev

The possible options are Device and Host. Host is not supported yet.

Lang

A language identifier. &H0409 for US/English

Man

A string constant with the manufacture name.

Prod

A string constant with the product name.

Serial

A string constant with the serial number.

 

The above settings determine how your device is displayed by the operating system.

Since these settings end up in flash code space, it is best to chose short names. There is no limit to the length other then the USB specifications impose, but keep it short as possible. Strings in USB are UNI coded. Which mean that a word is used for each character. with normal ASCII coding, only a byte is used for each character.

 

For a commercial USB device you need to give it a unique VID & PID combination. When you plan to use it at home, this is not needed.

You can buy a Vendor ID (VID) from the USB organization. This cost 2000 $.

As a service MCS offers a PID in the on line shop. This cost little and it gives you a unique Product ID(PID) but with the MCS Electronics VID.

 

 

noticeNotice that using CONFIG USB will include a file named USBINC.BAS. This file is not part of the BASCOM setup/distribution. It is available as a commercial add on. The add on package includes 3 samples , the include file, and a special activeX for the HID demo.

None of the samples require a driver. A small UB162 module with normal pins is available from the on line shop too.

The first supported USB devices are USB1287, USB162.
