In reply to EktanN_26, I expect the OP doesn't really mean 'host'. Just a slip in terminology, perhaps.
The CY8CKIT-059 is cheap and useable if you want to fiddle with USB. If you want to use 'pure' USB, you are constrained to using the Cypress drivers, (i.e. cyusb3.sys) and the Cypress VID (vendor ID) and PID (product ID) but you are only permitted to do this for evaluating the product or some such restriction. You categorically cannot use them commercially. Or, if you are rich, you could cough up a few thousand dollars to the USB Implementer' Forum for your own VID/PID.
The next option is to use the driverless model. This is for things like mice, keyboards and other standardised items that more or less do the same things. One possibility here is to use the COM port emulation where your USB device pops up as a serial port on the PC and you can then use old-fashioned serial communications software to exchange information.
There is also a little example called 'square mouse' or something like that that makes your mouse dance around your screen in a very un-murinelike manner. This demonstrates the HID mouse function and might entertain for a few minutes.
Also, on youTube, there is a demo of USB code which works but is a bit tricky to follow.
The CY8CKIT-059 has a break-off programmer / debugger. This will also work with other PSoC parts and is as good as the MiniProg3 at a fraction of the cost.
