Question: Why does the USB® HX2VL™ crystal stop after the hub out from reset?
Answer: The crystal stops operation in Suspend mode. When there is no activity on the upstream USB bus for more than 3 ms, HX2VL enters suspend mode. Therefore, when you reset HX2VL with no devices connected to any of the downstream ports, HX2VL goes into Suspend mode and the crystal stops operation.
