This is working here, I've put 16 partitions on a CompactFlash in my USB flash reader and all the devices are there, including the main devices for the three empty slots. Greg, what device you are using? I want to reproduce it, but it is not slow enough :) But there is still a problem: Jan 3 20:20:00 pim udev[30927]: namedev_name_device: sysfs_device->path='/sys/devices/pci0000:00/0000:00:1d.0/usb1/1-1/1-1.4/1-1.4:1.0/host53/53:0:0:0' Jan 3 20:20:00 pim udev[30927]: namedev_name_device: sysfs_device->bus_id='53:0:0:0' Jan 3 20:20:00 pim udev[30927]: namedev_name_device: sysfs_device->bus='unknown' sysfs_get_classdev_device() called from get_sysfs_device() in the wait loop in namedev.c is to fast. It returns the sysfs_device but the "device" link is not ready at this time and sysfs_get_classdev_device() sets sysfs_device->bus to 'unknown'. We need to wait for the "device" link until we can get the bus value out of it. thanks, Kay ------------------------------------------------------- This SF.net email is sponsored by: IBM Linux Tutorials.
