In the datasheet I have found that in the bus-powered device I do not need to use SoftConnect pin in order
to pull D+ line. Instead I can use pull-up resistor.

In some other application notes for development kits I have found that it is recommended to use SoftConnect

pin in order to pull the D+ line by software.

What are the recommendations regarding SoftConnect functionality. My application implements USB device using LPC1756 MCU.

Best regards,
