Non-networked access to RB 751U possible?

I’m used to using the RBs that have serial ports and didn’t notice that some of the newer models no longer have them. Does this mean that the RB 751U can only be accessed through it’s network ports?

Can I get console access to the RB 751 directly through the USB port?

you can look here for supported devices:

I understand that certain USB->Serial solutions are allowed (i.e. http://www.newegg.com/Product/Product.aspx?Item=N82E16812120751), but I was wondering if it is possible to connect from say a laptop with only a USB connection to the MT (i.e. USB to USB) or would you need to do something convoluted like:

Laptop: USB → serial | serial cable | serial → USB | Mikrotik

Direct USB connection between RB751U and PC will not work.

However this setup works:
Laptop: USB -> serial | serial cable | serial -> USB | Mikrotik

Just make sure USB port has correct baud-rate in Port List and USB port is used as Console port.

Thank you!
