Hello,
please review our schematic of TUSB2077A. We have a problem with the enumeration.
Not all devices are always enumerated at the HUB. At least 1 or sometimes 2 devices are not recognized at every boot. The hub is used in an embeddd system. All connected devices are on the same pcb. Two ports are not used and are routed to one connector. A 6MHz Crystal is used.
Attached is our schematic. The routing is accoriding to USB standard.
OS is Windows 10 and Ubuntu.
