Hi,
Startup finished in 8.394s (firmware) + 590ms (loader) + 918ms
(kernel) + 19.389s (initrd) + 1.940s (userspace) = 31.234s
~19.4 seconds during initrd seems like a bit much ... looking at the
log output I have noticed this:

So the questions are 1) what do those message actually mean? Seems
like everything works anyway 2) why do those block the boot process
... its not like the root fs is on a usb driver or something.
Kernel is 3.14.3-200.fc20.x86_64 (but does this not seem to matter it
happens for pretty much every kernel for almost every but not all boot
ups).
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 007: ID 8087:07dc Intel Corp.
Bus 001 Device 006: ID 0bda:58b1 Realtek Semiconductor Corp.
Bus 001 Device 012: ID 04f3:009b Elan Microelectronics Corp.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Any ideas where to investigate? Those error messages are really
cryptic and do not tell me anything.
-71 means EPROTO, note the device causing these issues is likely not
in your lsusb output since it fails to enumerate.
linux/Documentation/usb/error-codes.txt says the following about EPROTO:
-EPROTO (*, **) a) bitstuff error
b) no response packet received within the
prescribed bus turn-around time
c) unknown USB error
(*) Error codes like -EPROTO, -EILSEQ and -EOVERFLOW normally indicate
hardware problems such as bad devices (including firmware) or cables.
(**) This is also one of several codes that different kinds of host
controller use to indicate a transfer has failed because of device
disconnect. In the interval before the hub driver starts disconnect
processing, devices may receive such fault reports for every request.
Your boot log indicated that eventually the device on Bus 1 port 4
does enumerate and is the "Elan Microelectronics Corp." device which
likely is a touchscreen or a touchpad (if this is a tablet device
with a keyboard dock). Possibly the cable from the touchpad / touchscreen
has a loose contact somewhere.
