Hi Sorry for late reply, Since i was busy last week for 1 of my course exam and lab assignments . Now Iam free . Yes shall we schedule some time to discuss about the USB front end driver. Let me share some of my understandings i had , when i did a Linux kernel and Device drivers course which includes USB device driver . I did this course under a famous corporate trainer Raghu Bharadwaj in Veda Institute of technology, Hyderabad India. I did some coding and testing with character and block device drivers. Before my masters studies I worked for couple of design and maintenance of Embedded linux device drivers such as MCP23s17 and DSC11531 DAC chips and testing the Embedded software for Data distribution unit and further i worked on implementing Remote UI for sound bar EVM with 2 core Omap SoC . I understood the basics of USB Stack for any USB device , 6 device classes for USB driver and its data transfer types and 4 descriptor structures described in USB specification and further the Lifecycle of URB request blocks which is an important concern for coding and implementation of USB device drivers In my opinion USB is more of implementing Library functions and frame level application data transfer . An USB driver data transfer can also be Char/Block/Network drivers with some registration layer, file operations structure changes. Kindly mention your convenient time on coming wednesday or thursday and Im in Sweden so I need to check corresponding CET time on these days to fix timing . My skype id is gokulnath.gokulnath1 Kindly reply me thanks and regards Gokul On Mon, Mar 16, 2015 at 7:18 AM, Hans Petter Selasky <hps@selasky.org> wrote: > Hi Gokul, > > Ping: Can you respond to this e-mail or are you one of those spam bots? > > --HPS >
