Greg, I'm sorry if I wasn't clear. I think your article is very good. My device is a simple bulk in & out (2 pipes) which fits nicely into the read()/write() model. For someone new to Linux kernel/device drivers but knows all about USB and Windows drivers I'm asking this:
**again, assume that the article answered questions about how to modify the code and that has been done** **I refer to skeleton source to make things clear - I know this should be renamed to my_usb.c or something like that** 1- How do I build the code as a module? It looks like the Makefile in /driver/usb is pretty straightforward. I suppose I have run "make modules" from TOPDIR - is this what you have to run every time you make a change to the skeleton source? Why descend into all of the modules? Is there a way to build JUST the usb modules, or better yet just the skeleton usb module? 2- What does "make modules_install" do? Apparently this is run after make modules. 3- Okay, so now I've got my skeleton.o or whatever. What has to be configured as far as hotplug goes to get it loaded when I plug in my device? We make a grand assumption that VID/PID were set up correctly in the skeleton.c file and that this matches the VID/PID of the device that is being plugged in! Assume there are no bugs either! 4- how do the /dev/usb entries get setup properly so I can open() the device from a user mode app.? All this is a pretty much a follow on to your article - kind of showing how to use usb-skeleton and something you probably do without thinking! :-) Thanks for your time... > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED]]On Behalf Of Greg KH > Sent: Friday, September 20, 2002 7:20 PM > To: Andrew Pargeter > Cc: [EMAIL PROTECTED] > Subject: Re: [linux-usb-devel] usb skeleton > > > On Fri, Sep 20, 2002 at 07:00:10PM -0400, Andrew Pargeter wrote: > > > > I am looking for a step-by-step to building the driver and getting it > > running.
