I have tested the same hardware with RH9, and it behaves correctly. So this is an issue with FC2 (I have not tested FC1). With the release of Knoppix (supporting kernel 2.6.5) I have tested with that, and it also works correctly. As a result I do not know if its a difference between FC2's kernel and Knoppix's kernel, or an issue with the remainder of the FC2 distribution versus the Knoppix distribution. I have also fetched and built kernel 2.6.6-rc3 and 2.6.6 and both exhibit the same failure when run within the FC2 environment. Apparently this is a buggy ACPI issue, with the same conclusion as: http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=115748 in comment #44. The workaround is to add a kernel parameter: acpi_os_name=xxxxxyyyyyzzzzzxxxxx What is interesting is that the kernel 2.6.6 supplied by Knoppix (aka. Debian) seems to take this into account and exhibited no problems although without the apparent kernel parameter (I couldn't find it). *** This bug has been marked as a duplicate of 115748 *** Changed to 'CLOSED' state since 'RESOLVED' has been deprecated. |
From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.6) Gecko/20040312 Description of problem: When testing my digital camera with gtkam, I discovered it wouldn't detect my camera. Upon further investigation it seems that the USB sub-system did not auto-detect the newly plugged in device. Using lsusb only shows the controllers. This problem exists regardless of the USB device type. When I had the camera (also tested with a web cam, and floppy) plugged in at boot time, the USB had the devices listed via lsusb, (and therefore functioned). As soon as the device was unplugged, the device was no longer visible with lsusb, nor operational. Version-Release number of selected component (if applicable): kernel-2.6.4-1.305 How reproducible: Always Steps to Reproduce: 1. plug in USB device. 2. reboot 3. use 'lsusb' to view the device's presence. 4. unplug the device. 5. use 'lsusb' to see the device gone. 6. plug in USB device. 7. use 'lsusb' to see that the device is still missing. Expected Results: The device should reappear when hot-plugged in. Additional info:
