There are a lot of compile-time options and many binaries are released with options modified than default in source or compiling too much options was resulting in unreliable builds so default is less things enabled
USB serial does..?. if you refer to US2 - usb port with soft-serial core yes I think it is disabled in default build because it doesn't work very reliable.
It's good for selftest to check that everything is wired ok

Yes, I mean US2 but it does not look disabled to me. C_sio is 2, C_usbsio is "0100" and C_clk_freq is 89 which provides clk_usbsio. There is a Windows toast notification that the USB device malfunctioned so it seems to be doing something.
I need to check this. with some settings US2 will work but expect it to loose serial packets. I think but Im not sure that some part of the USB higher level protocol like packet retry or similar is not implemeted properly. Lower level part of the protcol (RX side PC->US2) I have rewritten and I'm pretty sure is good now.
So I think still direction PC -> US2 packets get lost much more than in US2->PC direction.
