Transistors generally can't switch significant currents effectively. Also, they can't latch.

- LeifCarrotson 6y agoUh, citation needed? A typical MOSFET is abundantly capable of switching several amps of current, orders of magnitude more than you'll find in a USB system. Also, an SSR (whether MOSFET, IGBT, triac, or SCR based) doesn't latch either. Only some esoteric mechanical relays latch. I had a similar requirement to OP, though my USB hardware was fine, it was a third party device that would sometimes fail to connect when the system restarted. A watchdog reset of the uC trivially reconnected my hardware, but I resorted to enabling/disabling the AHCI driver to force Windows to re-enumerate USB devices to get that to be reliable.
