Dear Friends, In an attempt to create a small linux system, I recompiled kernel 2.6.5-1.358 on FC2, taking out many unwanted options. I kept CONFIG_HOTPLUG=y because I want USB hotplugging. After the recompilation and copying the filesystem to a smaller partition, I noticed that although the USB device is detected by the kernel when I plug it in (see log below), the usb.agent script is not called as on a normal Fedora install. Does anyone have any idea what could be the problem or tell me the necessary things that must be in place for USB hotplugging to work. usbdevfs and sysfs are both mounted. Thank you, John Stripped down linux system logs ==================================== Jul 5 10:17:34 localhost kernel: usb 1-2: new full speed USB device using address 3 Jul 5 10:17:34 localhost kernel: usb 1-2: configuration #1 chosen from 2 choices Normal Fedora install logs ========================================= Jul 5 10:17:34 localhost kernel: usb 1-2: new full speed USB device using address 3 Jul 5 10:17:34 localhost kernel: usb 1-2: configuration #1 chosen from 2 choices Jul 5 10:17:34 localhost kernel: usbserial 1-2:1.0: Keyspan 1 port adapter converter detected Jul 5 10:17:34 localhost kernel: usb 1-2: Keyspan 1 port adapter converter now attached to ttyUSB0 (or usb/tts/0 for devfs) Jul 5 10:17:36 localhost usb.agent[3274]: Keeping default configuration with /sys//devices/pci0000:00/0000:00:1f.2/usb1/1-2 __________________________________ Do you Yahoo!?
