Hello,
I need to write a new driver for a Philips ISP1122A USB hub.
My USB Host controller is a SL811HS Root Hub and I have connected the
ISP1122A to it.
I'd like to know the main guidelined about how to create this USB driver,
maybe an existing driver in the kernel I can use as skeleton or example.
TIA
