feature: enable USB_RESET hook, and reset usb when hosts resets

[DacoTaco]

I don't know if you still accept PR's for this ancient version, but ive been using this project for years, and (very crappy) personal fork of this + the nes/snes code. However, i hated the fact that after every windows reboot, i had to unplug and plug it back in, because the mcu kept getting power over usb, meaning the usb was never reset. Today i found that v-usb has a hook on the reset request from host, in which we deal with it with the usbReset function. I don't know if this is correct, but it does seem to work, as the device enumerated correctly after a reboot.

this fix could also be applied to your generic usb controller project
