Electronic – Making own Chromebook debug cable (SuzyQable)

I wanted to debug my chromebook so I was looking for SuzyQable which enables to activate debug features on chromebook. Unfortunately this cable is hard to get in my location so after noticing this https://chromium.googlesource.com/chromiumos/third_party/hdctools/+/master/docs/ccd.md#making-your-own-suzyq official google guide to make own diagnostic cable I decided to give it a try. At first I was a bit sceptical about it as the schematic diagram of SuzyQable (https://cdn.sparkfun.com/assets/9/e/f/8/2/951-00273-01_20180607_suzyqable_SCH_1.pdf) is far more advanced than what google is saying. However the hub seems not be necessary there. So I bought usb type A and C breadboards and connected pins exactly as described on chromium page linked above although with one caveat – I currently don't have 56K Ohm resistors so I connected in series:
56k Ohm = 22 + 22 + 10 + 1 + 1 [k ohm]

Once the whole setup is connected I measured voltage on CC1 & CC2 pins:

Voltage on CC1: Position 1 -> 4,81V; Position 2 -> 4,78 V

Voltage on CC2: Position 1 -> 0,44V; Position 2 -> 0,46V

Unfortunately after plugging it in the device is not recognizable as tty serial USB one, which should be visible under /dev/ttyUSBx

Obvious problems which I already eliminated:

1. They say chromebooks discover this debug interface in only on usb type c orientation so I already tried both, same effect.

2. I have usb to serial module (FT232R) I connected it to both devices (chromebook and Ubuntu host) and it was discovered as ttyUSB0 immediately. So this means both devices are serial capable.

Questions:

1. I wonder if the series connection, of 56 k ohm resistor, introducing voltage drop can be responsible for the issue?

2. Is the hub which is on sparkfun schematic really superfluous and can be ommited?

3. What voltage levels are needed for USB to be discoverable as serial device?

UPDATE:

My Chromebook model is: Acer Chromebook 311 bobba

PS: Chromebook sometimes log weird dmesg messages like:

"PDLOG (date here) P1 SINK (not charging) charger ?? 5000mV max 5000 mV / 500 mA"

Ubuntu on the other hand logs:

"usb usb1-port3: over current condition"
"usb usb1-port4: over current condition"

Yes I have no idea why it mentions two ports if I only tinker with one!

Thanks for any advice!
