Package: udev Version: 0.114-2 Severity: normal
Hello, In udev-0.105 the remove event of USB devices was passed so other programs like HAL can provide client programs with a chance to react to device removal. In udev-0.114, this is no longer being passed from the kernel. Here is a 'udevmonitor --kernel' of inserting a USB thumb drive. udevmonitor will print the received events for: UEVENT the kernel uevent UEVENT[1198443886.319723] add /devices/pci0000:00/0000:00:1d.7/usb4/4-1 (usb) UEVENT[1198443886.319780] add /class/usb_endpoint/usbdev4.2_ep00 (usb_endpoint) UEVENT[1198443886.319797] add /devices/pci0000:00/0000:00:1d.7/usb4/4-1/4-1:1.0 (usb) 8< snip a bunch of drive setup events >8 UEVENT[1198443906.647589] remove /devices/pci0000:00/0000:00:1d.7/usb4/4-1/4-1:1.0 (usb) UEVENT[1198443906.647605] remove /class/usb_device/usbdev4.2 (usb_device) UEVENT[1198443906.647619] remove /class/usb_endpoint/usbdev4.2_ep00 (usb_endpoint) UEVENT[1198443906.647634] remove /devices/pci0000:00/0000:00:1d.7/usb4/4-1 (usb) Note the ending remove event. Here is a 'udevmonitor --udev' of the same device: udevmonitor will print the received events for: UDEV the event which udev sends out after rule processing UDEV [1198443956.329178] add /devices/pci0000:00/0000:00:1d.7/usb4/4-1 (usb) UDEV [1198443956.340344] add /class/usb_endpoint/usbdev4.3_ep00 (usb_endpoint) UDEV [1198443956.341327] add /devices/pci0000:00/0000:00:1d.7/usb4/4-1/4-1:1.0 (usb) 8< snip a bunch of drive setup events >8 UDEV [1198443977.063430] remove /devices/pci0000:00/0000:00:1d.7/usb4/4-1/4-1:1.0 (usb) UDEV [1198443977.069623] remove /block/sda (block) Note the lack of the final removal event. This bug makes an application that reports on USB status to fail and causes HAL to endlessly increment the identifier for the same physical device.
