Some aplications (xscreensave, gnome-screensaver) begin to have problems. I only geting in \/var\/log\/auth.log this:

Interesting is error 0x194d. It’s only a few days since Elias Holman send to linux-biometrics conference this:<\/p>\n

\nHi,
\nI’m not sure if this is the place for this, but I don’t know where else
\nto ask. I have a new Toshiba M400 laptop running Fedora Core 5 that has
\nthe same fingerprint scanner as the ThinkPad (I believe…). It shows
\nup with the same description and device ID. However, after I get
\neverything installed and configured with bioapi, when I run the sample
\napplication, I get:<\/p>\n

BioAPI_ModuleLoad failed, BioAPI Error Code: 6477 (0x194d)<\/p>\n

even as root, so I don’t believe it is a permissions problem.
\nSupporting that position is that nothing appears in \/var\/log\/secure to
\nindicate access failure. Also, when I run with strace, I see the
\nfollowing (the device is at 003:002)
\n = 0
\nopen(„\/dev\/bus\/usb\/003\/002“, O_RDWR) = 12
\nioctl(12, USBDEVFS_SETCONFIGURATION, 0xbfab21c4) = 0
\nioctl(12, USBDEVFS_CLAIMINTERFACE, 0xbfab21c4) = 0
\nnanosleep({0, 10000000}, NULL) = 0
\nioctl(12, USBDEVFS_CONTROL, 0xbfab218c) = 1
\ngettimeofday({1152120959, 632108}, NULL) = 0
\nioctl(12, USBDEVFS_SUBMITURB, 0xbfab1914) = 0
\nioctl(12, USBDEVFS_REAPURBNDELAY, 0xbfab1958) = -1 EAGAIN (Resource
\ntemporarily unavailable)
\nselect(13, NULL, [12], NULL, {0, 1000}) = 1 (out [12], left {0, 1000})
\ngettimeofday({1152120959, 633112}, NULL) = 0
\nioctl(12, USBDEVFS_REAPURBNDELAY, 0xbfab1958) = 0
\nnanosleep({0, 10000000}, NULL) = 0
\ngettimeofday({1152120959, 647226}, NULL) = 0
\nioctl(12, USBDEVFS_SUBMITURB, 0xbfab1924) = 0
\nioctl(12, USBDEVFS_REAPURBNDELAY, 0xbfab1968) = -1 EAGAIN (Resource
\ntemporarily unavailable)<\/p>\n

It appears to be having trouble reading from the USB file system or
\ndevice? I am little confused at this point because of the way Fedora
\nhandles USBFS. It appears to be mounting \/dev\/bus\/usb at \/proc\/bus\/usb,
\nbut that doesn’t show up from mount. lsusb gives me back what you would
\nexpect, so I assume it is working. I am also 99% sure that the scanner
\nis functional because I tried it via Windows when I first got the laptop
\nbefore I wiped it and I was able to operate it with no trouble.
\nFollowing is the relevant lsusb output, in case anything jumps out at
\npeople. I am using a custom 2.6.15 kernel (with a few small, hopefully
\nirrelevant tweaks) based on 2.6.15-1.2054_FC5smp. I updated to
\nlibusb-0.12 just in case that was the issue. Any insight would be
\ngreatly appreciated.\n<\/p><\/blockquote>\n

I thing it is not coincidence. Really insightfull discussion is at thinkwiki<\/a>.<\/p>\n

Finaly it is definetly permission error. After removing suid bit xscreensaver run for me.<\/p>\n","protected":false},"excerpt":{"rendered":"
