In datasheets for HL7519 and HL7549, VBUS is described as a Supply for USB interface
While in HL8548, VBUS is also described as a supply
but an additional comment state it as a detection input
Could you please confirm that VBUS is only a sense input for HL8548?
Is it the same thing for HL7549? Or is it a really a supply (USB standard allows both configurations).
I intend to use a socket and build a solution compatible for all these parts.
