CY4608M Development Kit - Bug with SELF_PWR mosfet
I got lost using the search function, so I just want to report the bug I've just found to you. Appologies if that has been done before.
In the CY4608M HX2VL 4-port MTT USB 2.0 HUB Development Kit, there is a wrong transistor Q3 used in the schematic design and in the actual assembled board.
Q3 is a FDN338P p-channel MOSFET, but it has to be a n-channel transistor, in order to use the HUB as a self-powered USB device.
Hope this helps.
