That will be out of spec because it will be 49 ohms per leg.Due to the logistics of my project, my USB connector is actually placed on a breakout board around 15cm from the mainboard (and RP2040), so I added 22R on each of D+ and D- traces, close to the USB connector pins on the breakout board to help with signal integrity. Hopefully having the 22R and 27R in series won't cause any issues?
