I have tried mounting the satnav on a i386 box with both debian and stable 2.6.39-rc5 self compiled. Both report the "INQUIRY result too short", but nevertheless do generate the /dev/disk/by-id links which can then be used to mount and unmount the satnav. The debian kernal is much more noisy than 2.6.39-rc5, reporting many usb device resets.
Back on the amd64 box, where the device nodes are not craeted, I collected the reports from udevadm:- # udevadm monitor monitor will print the received events for: UDEV - the event which udev sends out after rule processing KERNEL - the kernel uevent <===== Satnav plugged in here ======> KERNEL[1304259432.206729] add /devices/pci0000:00/0000:00:10.4/usb1/1-4 (usb) KERNEL[1304259432.208411] add
