Connecting two USB 2.0 devices to a single USB port on an MCU
This would always be implemented using a switch IC rather than just a junction; with that, there'd be no stub line, no need for redriving.

Many silicon manufacturers do offer such ICs, many even explicitly specified for USB2 signaling. Check e.g. TI.com's selection of USB 2.0 switches. Or Maxim's. Or NXP's. Or  ON Semi's (show "ALL" instead of 50, search for USB). Or Analog Device's. Or intersil's (now Renesas). Or ROHM's.
