Добрый день.

Я отлаживаю железку, в которой USB Hub USB7216, структура железки выглядит примерно так:

там есть одноплатный ПК формата MXM3 (p/n EDM1-IMX6D-10-R10-MSD-9377) и в силу того, что у него один USB, к нему подключен USB-Hub на 6 портов USB7216. К мосту подключены уже USB-UART, микроконтроллер (его нет на картинке), и несколько соединителей USB. В качестве Reference Design использовать схему отладочной платы EVB-USB7216 (схема в pdf файле, во вложении). Я предполагал, что выбрав одну из двух предустановленных опций USB Hub, мне не надо будет его отдельно конфигурировать, и он должен сразу заработать. Сейчас, установлены перемычки J18,J19,J21,J25,J26,J27,J31-J37,J39,J71,J72 (выделены на схеме желтым). Но на практике я получил такое поведение: иногда он определяется как один хаб, иногда как два хаба, и чаще всего не определяется совсем. Во всех случаях, подключенные к хабу USB устройства не определяется операционной системой.

Это вывод с Linux, если мост определяется

вывод, когда он не определяется и когда определяется лишь его "часть" я не могу сейчас поймать что-то, как поймаю, дополню пост.

Когда определяется лишь "часть" устройства, он отображается примерно так

Bus 001 Device 083: ID 0424:4216 Standard Microsystems Corp.

Кто сталкивался с этим семейством USB Hub от MicroChip? В чём может быть причина? Буду рад любой помощи, спасибо.
