rb2011 + apc rs 1500va not work

Hello!
Got a really stuck with setup: rb2011 + apc rs 1500va.

RB2011UiAS-2HnD-IN, ROS 6.33.3 - package UPS installed.

I’ve connected it with a proprietary apc cable like this: (rj50 to usb) http://store.softline.ru/uploads/hardware_product/d2a4a1c804e0685808fd20402fe18a5cea5e2d00_1.jpeg
it is connected via mikrotik OTG cable to micro-usb on board. (tried to change OTG cable - no effect)

APC cable is fine, it works with win7 pc. Usb port on rb2011 is fine too, it works with usb hub and usb-modem.
I know about power-cycle usb feature on rb2011 board, so i’ve power it down (not reboot) - got no effect.

in /system/ups
If i choose port “serial0” - (system console diabled) - i got Ups1 with “!” sign in /system/ups with no data
if i choose usb2/usb3 - i got port is inactive.

Really wanna buy apc UPS to wotk with RB912UAG-2HPnD but have a bit affraid.

Does mikrotik works with usb-b to usb-a cable (no serial) APC ?

thanks.

Are you sure this model uses Smart-UPS signalling?

Try using a powered usb hub, maybe the UPS usb port needs to be powered.
