about driver development for USB

[arun397]

hi
i have been posting quires about my project here. thanks for all the replies.

my project is USB Device Core development on FPGA.

i would like to know whether it is need to develop drivers (for the device developed) to be detected or can i use the windows drivers itself.

and i have to use a controller in it instead i have used a state machine. so do need to include both or state machine is sufficient.

thanks

Whether to use a standard Windows USB driver or develop your own depends on your application. For example, if your application is like a (low-speed) human device interface, you may want to write the FPGA-side so that it appears as a standard USB HDI device. This way, you don't have to develop your own driver.

Writing a Windows device driver is not that difficult with the right books. There are a few good books (Oney, Cant)
