+There are cheap clones of simple CMSIS-DAP interfaces from China.
+They support ARM SWD and UART I/O when they actually work which
+is a rare occurrence. I gave up with it now.
+They are unable to reset the target which may be a problem when
+the target is in sleep mode.
+These devices may not work on some unpowered hubs since they
+demand 500mA current.
+NB Always wire the ground wire even if you think you do not need to.
