Bugzilla Bug 252997

I am using Gentoo Linux. I updated kernel to 2.6.28 yesterday. Everything is ok
except thinkfinger, gphoto2 and fprint.  The three packages work fine on 2.6.27
on my laptop.
There is a fingerprint reader on my laptop.
$ lsusb
Bus 005 Device 002: ID 0483:2016 SGS Thomson Microelectronics Fingerprint
Reader
$ ls -l /dev/bus/usb/005/002
crw-rw-r-- 1 root usb 189, 513 Dec 30  2008 /dev/bus/usb/005/002

thinkfinger depends on libusb-0.1.12. Its tf-tool opens /dev/bus/usb/005/002,
and fails because usb_bulk_read return -2.
fprint depends on libusb-1.0. It fails because submit_bulk_transfer return -1,
errno = 2

After my Canon camera was connected to my laptop with USB cable, gphoto2
successed first time when I executed it, but second time, it failed with I/O
error.

Please, submit your "emerge --info" and "emerge -pv libusb gentoo-sources" and
any dmesg output. 

Kernel bug, fixed by the patch you can find here:
http://bugzilla.kernel.org/show_bug.cgi?id=12301

More details here: http://article.gmane.org/gmane.linux.usb.general/13442

OK, that kernel patch works for me. This is actually a kernel bug. This bug can
be closed.

Please don't close bugs until the fix is shipped in gentoo-sources.

According to http://bugzilla.kernel.org/show_bug.cgi?id=12301#c23 the patched
was finally commited to mainline, so I think the patch can finally be included
with gentoo-sources.

yep thanks, the InSVN keyword means it is already queued for next release

fixed in gentoo-sources-2.6.28-r1

I think, something more serious is going on!

I'm using libusb to upload to a Lego NXT brick running the LeJOS firmware.
Uploading doesn't work anymore while it works perfect using kernel 2.6.27.x.
