求助：升级后指纹不能用了

michaelyeah

周末把gentoo在线升级后发现thinkfinger不识别之前存储的指纹， 然后试了一下tf-tool --verify-user foobar, 报错：
Initializing...Could not claim USB device.

strace tf-tool --verify-user foobar结果：
open("/dev/bus/usb/003/003", O_RDWR)    = 5
ioctl(5, USBDEVFS_IOCTL, 0xbfb139a0)    = -1 ENOTTY (Inappropriate ioctl for device)
close(5)                                = 0
open("/dev/bus/usb/003/002", O_RDWR)    = 5
ioctl(5, USBDEVFS_IOCTL, 0xbfb139a0)    = -1 ENOTTY (Inappropriate ioctl for device)
close(5)                                = 0
open("/dev/bus/usb/003/001", O_RDWR)    = 5
ioctl(5, USBDEVFS_IOCTL, 0xbfb139a0)    = 3
close(5)                                = 0
open("/dev/bus/usb/003/003", O_RDWR)    = 5
ioctl(5, USBDEVFS_CLAIMINTERFACE, 0xbfb13a04) = -1 EBUSY (Device or resource busy)

这个是什么原因呢？ google了好久没弄明白。

看看dmesg的内容，或许对你有帮助。

dmesg我也看过，没什么收获。。

照这上面把设备设置成auto也不行。
