Description of problem: Whenever I boot my linux and the system is up, hotplugging of usb devices does not work. There are NO entries in /var/log/messages. The kernel seems not to recognize the new devices. But if I boot the system with the devices plugged in, they are ok, and I can use them. ps -A states the daemon khubd is running. I get no error messages during boot in /var/log/messages. The /proc/interrupts tells, usb-uhci is configured on irq 10 and 11. it says usb-uhci, PCI device 1542:1421 (ENE Technology) My system is a laptop with acpi enabled. There is the intel 855GM chipset in it. Two USB interfaces are found by scanpci: 82801DB I have two usb devices, a mouse, and a storrage drive. both are working on redhat 9 (a desktop system), and when booting with them. It seems, the usb stuff is out of power, when the system is up and so the kernel does not receive any signal when plugging. Or perhaps the khubd is not responding. perhaps a hardware issue? Today I installed hotplug the newest version, no changes. ehci-hcd does not load: No such device Version-Release number of selected component (if applicable): Fedora Core 1 kernel 2.4.22-1.2135.nptl acpi=on apm=off hotplug 2003_08_05 USB 2.0 How reproducible: always Steps to Reproduce: 1. boot 2. plug in usb device 3. no reaction Actual results: none Expected results: hotplugging like on every other computer Additional info: please ask
