Device not found error while using base10 value

[sramar]

Software branch : v1.1.0
I'm using base10 value "scat -t qc -u -a 1256:26717 -i 2" but getting error "Device not found". Can you please help on this issue

lsusb commands output : Bus 004 Device 006: ID 04e8:685d Samsung Electronics Co., Ltd GT-I9100 Phone [Galaxy S II] (Download mode)

scat -t qc -u -a 1256:26717 -i 2
Trying USB device at address 1256:26717

-a is the USB bus/device address, not the VID/PID. Please use -v 0x04e8 -p 0x685d or -a 004:006 instead.
