USB Hub Design Documentation

Thought for 4 mins 1 sec

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:

Try again later once the library fetch issue clears
Use USB2514B/M2 instead of USB2514B-I/M2
Create custom project parts for USB2514B-I/M2 and MIC2025-1YMM, then place those

If you want, I can try the alternate USB2514B/M2 path next.

Try alternate hub
