reading from a usb device
Posted: Wed Jul 07, 2010 11:53 am
hello all
I am trying to write and read from an usb device like USB mouse and USB keyboard.I am using windows APIs in vb6.The problem is like this.whenever i call the APIs readfile and writefile, it returns 0 and does not return any data.Before reading data,I have successfully called APIs to detect the device name and its pid. Does any one know the reason why the bytes returned is always 0.Any type of help will be highly appreciated.
