Can Microbrute do Midi->USB of external SysEx messages?

[Snag]

Hi!
I'm trying to SysEx dump from my Boss DR-670 drum machine into SysEx Lybrarian (Mac Os) using my Microbrute as a midi-usb interface. I connected Midi Out from DR-670 into Midi In of Microbrute and connect Microbrute to the Mac Book via USB cable.
Then I start dumping procedure from Boss but nothing come to the SysEx Librarian and Microbrute seems stuck and need to be restarted (power off/on)
The question is - can Microbrute pass SysEx messages as midi-usb interface into computer ?
Thanks.
