We have a test jig that at some point have to disconnect our device from the computer USB (12Mbps variant) and than reconnect after performing a few tests. Currently, to emulate a physical disconnection we are using relays. It works as expected, but maybe a solution as the TI ts3usb221a would be a more reasonable one. What would be the differences between both scenarios: real physical disconnection and FET disconnection with the ts3usb221a. Our mains concern here is related to some current leakage as one of the tests that are performed is measuring a few microamps of consumption of the board.
PS: As we are are already going to use a hub as the TUSB2036 to connnect both the Jig and the tested device with a single USB connector, would be possible to control the HUB to emulate a disconnection of that port?
