I am now playing with your udev:-), and I encounter some problems. I use a usb mouse as a PnP devices, after I mount sysfs, I can not find any devices in /sysfs/devices/pci0/00:0f.2 as DEVPATH=/devices/pci0/00:09.0/usb1/1-1/1-1.1/ttyUSB7 in the test file udev supplied. 00:0f.2 is my USB controller, ls /sysfs/devices/pci0/00:0f.2 class irq power subsystem_device vendor device name resource subsystem_vendor So I think the configuration files you given out is for usb hub,is that right? For the common USB mouse, can I only configure DEVPATH=/sysfs/devices/pci0/00:0f.2? I tried this,but no results. Could you please tell me what cause this problem?

As for the progress of libsysfs, yes, there are some people working on it.

It will use the /sbin/hotplug hook that the current linux-hotplug release uses. Does that explain what you are asking? And there is already a version of udev "released" it's on the kernel.org site if you want to play with it. > I think there are some tasks are waiting to do, so could you please > tell the detailed progress in current udev project? Most of the work has been on the OLS presentation lately, but after OLS a lot more time will be available to work on it. If there's any part of udev that you want to help out on right now, feel free to let me know. thanks, greg k-h ------------------------------------------------------- This SF.Net email is sponsored by: INetU Attention Web Developers & Consultants: Become An INetU Hosting Partner.
