Now also tried gentoo-sources-2.6.14-r2, same problem.
I've seen the same issue for a while now. The problem is described here at http://bugzilla.kernel.org/show_bug.cgi?id=5063 which indicates that libgphoto2 2.1.6 should fix the problem. I see that you are using 2.1.5 so that may fix it for you but I've got 2.1.6-r1 and am still seeing the exact same problem (-EBUSY on a USBDEVFS_SETCONFIGURATION ioctl) If you strace the gphoto2 run you should see something like the below right before it errors out. ioctl(5, USBDEVFS_SETCONFIGURATION, 0xbfda7f34) = -1 EBUSY (Device or resource busy) gettimeofday({1132112423, 363219}, NULL) = 0 write(2, "3.606017 gphoto2-port(0): ", 263.606017 gphoto2-port(0): ) = 26 write(2, "Could not set config 0/1 (Device"..., 50Could not set config 0/1 (Device or resource busy)) = 50 write(2, "\n", 1 ) = 1 gettimeofday({1132112423, 363459}, NULL) = 0 write(2, "3.606257 context(0): ", 213.606257 context(0): ) = 21 write(2, "Could not apply USB settings", 28Could not apply USB settings) = 28 write(2, "\n", 1 ...
Updating libgphoto2 to 2.1.6 fixes the problem. However, portage doesn't automatically indicate that a newer version is available with emerge -pu world, only with emerge -pu libgphoto2. Should be set to update for everybody running stable branch.
I have libhphoto 2.1.6-r1 and kernel 2.6.14 and i have some problem. gphoto2 -P *** Error *** An error occurred in the io-library ('Error updating the port settings'): Could not release interface 1 (Invalid argument). *** Error (-37: 'Error updating the port settings') *** gphoto2 -P --debug ............. 0.888952 gphoto2-port-info-list(2): Loaded '' (^serial) from 'libgphoto2_port_serial.so' 0.928746 gphoto2-port-info-list(2): Loaded 'Universal Serial Bus' (usb:) from 'libgphoto2_port_usb.so' 0.959263 gphoto2-port-info-list(2): Looking for path 'usb:' (2 entries available)... 0.959626 gphoto2-port-info-list(2): Getting info of entry 0 (2 available)... 0.959769 gphoto2-camera(2): Setting port info for port 'Universal Serial Bus' at 'usb:'... 0.960662 gphoto2-port(2): Setting timeout to 5000 millisecond(s)... 1.000020 gphoto2-port(2): Setting settings... 1.000098 gphoto2-setting(2): Setting key 'port' to value 'usb:' (gphoto2) 1.000174 gphoto2-setting(2): Saving 2 setting(s) to file "/root/.gphoto/settings" 1.001068 gphoto2-camera(2): Listing files in '/'... 1.039438 gphoto2-camera(2): Initializing camera... 1.039591 gphoto2-port-usb(1): Looking for USB device (vendor 0x41e, product 0x400b)... found. 1.039673 gphoto2-port-usb(1): Detected defaults: config 1, interface 0, altsetting 0, inep ffffffff, outep ffffffff, intep ffffffff, class ff, subclass 00 1.039747 gphoto2-camera(2): Loading '/usr/lib64/gphoto2/2.1.6/libgphoto2_pccam600.so'... 1.040045 gphoto2-port(2): Opening USB port... 1.040286 gphoto2-port(0): Could not query kernel driver of device. 1.068714 pccam(2): Initializing the camera 1.068896 gphoto2-port(2): Setting settings... 1.068992 gphoto2-port-usb(2): releasing the iface for config failed. 1.069165 gphoto2-port(0): Could not set config 1/1 (Device or resource busy) 1.069267 gphoto2-port(2): Closing port... 1.069354 gphoto2-port(0): Could not release interface 1 (Invalid argument). 1.108665 context(0): An error occurred in the io-library ('Error updating the port settings'): Could not release interface 1 (Invalid argument). *** Error *** An error occurred in the io-library ('Error updating the port settings'): Could not release interface 1 (Invalid argument). *** Error (-37: 'Error updating the port settings') *** ................... strace gphoto2 -P open("/usr/lib64/gphoto2/2.1.6/libgphoto2_pccam600.so", O_RDONLY) = 5 read(5, "\177ELF\2\1\1\0\0\0\0\0\0\0\0\0\3\0>\0\1\0\0\0 \24\0\0"..., 640) = 640 fstat(5, {st_mode=S_IFREG|0755, st_size=14384, ...}) = 0 mmap(NULL, 1060808, PROT_READ|PROT_EXEC, MAP_PRIVATE|MAP_DENYWRITE, 5, 0) = 0x2aaaac84c000 mprotect(0x2aaaac84f000, 1048520, PROT_NONE) = 0 mmap(0x2aaaac94e000, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_FIXED|MAP_DENYWRITE, 5, 0x2000) = 0x2aaaac94e000 close(5) = 0 open("/proc/bus/usb/002/012", O_RDWR) = 5 ioctl(5, USBDEVFS_GETDRIVER, 0x7ffffffe7560) = -1 ENODATA (No data available) ioctl(5, USBDEVFS_CLAIMINTERFACE, 0x7ffffffe767c) = 0 ioctl(5, USBDEVFS_RELEASEINTERFACE, 0x7ffffffe757c) = -1 EINVAL (Invalid argument) ioctl(5, USBDEVFS_SETCONFIGURATION, 0x7ffffffe757c) = -1 EBUSY (Device or resource busy) ioctl(5, USBDEVFS_RELEASEINTERFACE, 0x7ffffffe76cc) = -1 EINVAL (Invalid argument) munmap(0x2aaaac84c000, 1060808) = 0 write(2, "\n", 1 ) = 1 write(2, "*** Error *** \n", 28*** Error *** ) = 28 write(2, "An error occurred in the io-libr"..., 123An error occurred in the io-library ('Error updating the port settings'): Could not release interface 1 (Invalid argument).) = 123 write(2, "\n", 1
