Hi.... I'm a senior student doing a project related to RFID application. Can anybody tell me how to do a Visual Basic Program to interface a device with the PC through the USB? Also, can you tell me the IO Port Address of USB on the PC? Thanx
 

You may build a DLL (normally in C) interface with your USB device and invoke its communication functions in VB. You may also use an ActiveX control (easy job in VC++) instead of DLL, because accessing it is much easier in VB.
