functions for communiating with USB

[cool]

Hi,

I am currently using VS2010. I would like to know what are the functions and header files to call for sending data to USB and receiving data from USB?

Please Advice

Thanks

From my USB FAQ:

How an application communicates with a USB device depends on the device driver that Windows has assigned to the device. The choice of driver in turn depends on finding a match between the information in the descriptors that Windows retrieves on device attachment or bootup and the information stored in the PC's INF files. Typically, the application doesn't have to know whether the device uses USB or another interface. For example, applications access files on a drive in the same way whether the drive uses USB, IEEE-1394, SCSI, ATAPI, or another interface. The interface-specific details are handled at a lower level. Some devices use drivers included with Windows. Others use a vendor-specific driver that he user must install.

Applications access a USB/serial adapter in the same way they access physical COM ports. The application doesn't have to know or care if the port is a physical serial port or a USB adapter.

Use the SerialPort class. See my examples here:
