USB Hub Design Documentation

I couldn’t place the parts yet because the library add operation failed on Flux’s side when I tried to add USB2514B-I/M2 / USB2514B/M2 and MIC2025-1YMM to the schematic.
What I confirmed from your linked sources in Reference Document:
  • Bus-powered mode should use CFG_SEL[1:0] = 10
  • Default ROM values are fine, so no external EEPROM is required
  • All downstream ports can remain enabled
  • Your ganged power approach is compatible with the hub configuration
I already submitted the tool failure internally.
If you want, I can do either next:
  • retry with different library entries for USB2514B/M2 and MIC2025-1YMM, or
  • create clean custom project parts for the hub controller and load switch, then place those instead.

retry it.

I retried it, but the add-to-schematic operation failed again on Flux’s side.
  • Failed while placing USB2514B-I/M2 and MIC2025-1YMM-TR
  • Error returned: storage.objects.get permission denied while fetching the library object
  • Your schematic is still empty, so nothing partial was added
Best next options:
If you want, I can try the alternate USB2514B/M2 path next.
