This is the WORKING situation:
open("/dev/usb/hiddev0", O_RDWR)        = 3
ioctl(3, HIDIOCGDEVINFO, 0xbfa71a48)    = 0
ioctl(3, HIDIOCAPPLICATION, 0)          = -6291455
ioctl(3, HIDIOCGSTRING, 0x804e2c0)      = 7

the is the FAILURE situation (2.6.29-rc*):
open("/dev/usb/hiddev0", O_RDWR)        = 3
ioctl(3, HIDIOCGDEVINFO, 0xbf90c0d8)    = 0
ioctl(3, HIDIOCAPPLICATION, 0)          = -6291455
ioctl(3, HIDIOCGSTRING, 0x804e2c0)      = -1 ENODEV (No such device)
