After upgrading to udev-144 I could not mount my Nikon D40 camera as a USB storage device any more. Turns out the device doesn't like it when one accesses its last sector (or past last sector) and stops working from that moment on. Subsequent reads will return IO errors. The problem is caused by RAID scans of vol_id as RAID disks store a special block in their last sector. As it makes no sense to scan for RAID on a camera, I just added --skip-raid to all vol_id calls in /etc/udev/rules.d/. Then it worked. There should be a way to disable the RAID checks per device, or globally or some other way. Reproducible: Always Steps to Reproduce: 1. Use udev-144 2.

kernel is broken, not udev. Bug 185517, Bug 186326, Bug 188521 and we'll probably a special one for every single type out there.
Can you please attach the output of: cat /proc/bus/usb/devices with your Nikon D40 plugged in? Thanks.

Ortwin, Will you be submitting this upstream, or do you want us to do it on your behalf?
Mike, I have submitted the patch to linux-usb-devel@lists.sourceforge.net with a subject line "[PATCH] Nikon D40 Quirks" a couple of minutes ago.
Patch has been committed to mainline: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=9374b9fd6cef7f8b75a543d044c5b0925aae08cd Will be in 2.6.23
Reopened in anticipation of this patch eventually getting into genpatches for 2.6.22 Bug will be closed once the gentoo-sources revision containing the patch is released.
fixed in genpatches-2.6.22-8 / gentoo-sources-2.6.22-r7
(In reply to comment #10) > fixed in genpatches-2.6.22-8 / gentoo-sources-2.6.22-r7 > Could the bug maintainer get the following added to unusual_devs.h as well, it adds in support for the newer D40X with 1.00 firmware revs UNUSUAL_DEV( 0x04b0, 0x0417, 0x0100, 0x0100, "NIKON", "NIKON DSC D40X", US_SC_DEVICE, US_PR_DEVICE, NULL, US_FL_FIX_CAPACITY), I've been fighting for the past few weeks to get my new camera working and couldn't for the life of me figure out why adding an "X" to the model descriptor of the entry for the standard D40 until I realized the last two hex codes were revision markers. As of today (2007.10.08) on vanilla-sources 2.6.23-rc9 this works fine. ryn ~ # lsusb -v -s 001:005 Bus 001 Device 005: ID 04b0:0417 Nikon Corp.

Shan, Please post the output of: cat /proc/bus/usb/devices with your Nikon D40X plugged in.
Reopened and waiting for user response. Sorry for bugspam.
Created attachment 133142 [details, diff] D40X patch against 2.6.23 Patch to submit upstream
Submitted upstream: http://marc.info/?l=linux-usb-devel&m=119211659617632&w=2
Already checked into the usb git kernel tree and will show up in the 2.6.24 release. I can add this to the .23 stable if needed.
Patched commited to genpatches for 2.6.22 and 2.6.23 so they will be in the next patch released for both versions when that occurs. Bug will be closed once the gentoo-sources revision containing the patch is released.
Please note that genpatches-2.6.23-2 has been released with this patch included, gentoo-sources-2.6.23-r1 is using it.
also fixed in gentoo-sources-2.6.22-r10
