I used strace and the result is bus is busy:

clock_gettime(CLOCK_MONOTONIC, {8158, 708518222}) = 0
timerfd_settime(11, TFD_TIMER_ABSTIME, {it_interval={0, 0}, it_value={8159,
708518000}}, NULL) = 0
ioctl(12, USBDEVFS_SUBMITURB, 0x40810)  = 0
poll([{fd=7, events=POLLIN}, {fd=9, events=POLLIN}, {fd=11, events=POLLIN},
{fd=12, events=POLLOUT}], 4, 60000) = 1 ([{fd=12, revents=POLLOUT}])
ioctl(12, USBDEVFS_REAPURBNDELAY, 0xbecf8f24) = 0
timerfd_settime(11, 0, {it_interval={0, 0}, it_value={0, 0}}, NULL) = 0
ioctl(12, USBDEVFS_REAPURBNDELAY, 0xbecf8f24) = -1 EAGAIN (Resource
temporarily unavailable)
clock_gettime(CLOCK_MONOTONIC, {8158, 735783474}) = 0
timerfd_settime(11, TFD_TIMER_ABSTIME, {it_interval={0, 0}, it_value={8159,
735783000}}, NULL) = 0
ioctl(12, USBDEVFS_SUBMITURB, 0x40810)  = 0
poll([{fd=7, events=POLLIN}, {fd=9, events=POLLIN}, {fd=11, events=POLLIN},
{fd=12, events=POLLOUT}], 4, 60000) = 1 ([{fd=12, revents=POLLOUT}])
ioctl(12, USBDEVFS_REAPURBNDELAY, 0xbecf8f24) = 0
timerfd_settime(11, 0, {it_interval={0, 0}, it_value={0, 0}}, NULL) = 0
ioctl(12, USBDEVFS_REAPURBNDELAY, 0xbecf8f24) = -1 EAGAIN (Resource
temporarily unavailable)
ioctl(12, USBDEVFS_CLAIMINTERFACE, 0xbecf910c) = -1 EBUSY (Resource busy)
ioctl(12, USBDEVFS_GETDRIVER, 0xbecf9024) = 0
ioctl(12, USBDEVFS_CLAIMINTERFACE, 0xbecf910c) = -1 EBUSY (Resource busy)
ioctl(12, USBDEVFS_GETDRIVER, 0xbecf9024) = 0
ioctl(12, USBDEVFS_CLAIMINTERFACE, 0xbecf910c) = -1 EBUSY (Resource busy)
ioctl(12, USBDEVFS_GETDRIVER, 0xbecf9024) = 0
ioctl(12, USBDEVFS_CLAIMINTERFACE, 0xbecf910c) = -1 EBUSY (Resource busy)
ioctl(12, USBDEVFS_GETDRIVER, 0xbecf9024) = 0
writev(2, [{"Can't claim USB device [0463:fff"..., 62}, {NULL, 0}], 2Can't
claim USB device [0463:ffff]: No such file or directory
) = 62
exit_group(1)                           = ?
+++ exited with 1 +++

Why?

My ups is: 
[qnapups]
 driver = usbhid-ups
 port = auto
 desc = Eaton 5SC 500i
 vendorid = 0463*
 serial = G131F50027
 synchronous = no
 pollonly
 pollfreq = 10
 nolock
