hotplug would seem to work otherwise, except that it doesn't recognise CF cards in the Sandisk ImageMate otherwise than restarting it... Reproducible: Always Steps to Reproduce: 1. Install 2.6.3 ~x86 system with nptl support via linux-headers-2.6.1 2. Plug the sandisk imagemate into the machine and try to plug it into the system and access the cf card in it. 3. restart hotplug and try again and access it... Actual Results: 2. Didn't get access to the device nor the CF, output being: Feb 19 18:42:01 gentoo usb 3-1: new high speed USB device using address 2 Feb 19 18:42:01 gentoo usb 3-1: device not accepting address 2, error -71 Feb 19 18:42:01 gentoo usb 3-1: new high speed USB device using address 3 Feb 19 18:42:01 gentoo Initializing USB Mass Storage driver...

Not a hotplug issue. You need to run 'eject' to tell the kernel that your device is gone.
Okay, actually noticed that if I unplug the Imagemate from the cradle that came with it and reinsert it with the CF card into the cradle the CF card is noticed, but then again nothing happens if I just push a CF card into the Imagemate while it's attached to it's cradle. And now at udev 021 + kernel 2.6.4.
Sorry, but there is nothing that udev or the kernel can do to detect this type of action. I recommend using the {all_partitions} option in udev for whatever you name this device, that way the kernel will know to rescan the partition table for new devices.
