hi to all: I am considering about usb based console, just like vga based console or serial based console. What I want to know is technical difficulty on implenting usb based console if this thought can be carried out. I suppose that I use "minicom" to talk about ttyUSB or such like on PC, and the target can be regard as usb device.Between PC and target,we use a usb-line to connect.I think the transfer speed of usb based console is much faster than normal serial. any help appreciated! --http://www.eyou.com --Îȶ¨¿É¿¿µÄµç×ÓÐÅÏä ÓïÒôÓʼþ Òƶ¯ÊéÇ© ÈÕÀú·þÎñ ÍøÂç´æ´¢...ÒÚÓÊδ¾¡ --http://vip.eyou.com --¿ì¿ìµÇ¼ÒÚÓÊVIPÐÅÏä ×¢²áÄúÖÐÒâµÄÓû§Ãû -- Kernelnewbies: Help each other learn about the Linux kernel.
