Oh, I have hoped that I was developing to the hardware underlying driver. Originally, the major is the circuit. I have done some of the USB driver in the past two years. Although I can use it, I have been uncomfortable in my heart. I have a total of WDM. It feels a bit of a bit of a bit, so in the holidays in the holidays are realized, now I have a little bit, but I don't really write a thorough driver, always a little guilty, huh, huh, sticked a post, before BBS, I wrote it I wrote I don't know where to go, so I will pass it directly.
