I am experiencing very unreliable operation of the AD BlackFin BF-527 USB port (host mode, high speed). It seems to be a hardware problem. Did anyone accomplish a successful operation of the BlackFin USB port as a high speed host mode?
There is the USB_RSET pin on the port, which presumably sets the output current and/or termination of the USB. The datasheet is vague on the purpose and the connection of this pin. The AD support is silent. Do you know what could this pin be (may be, by analogy with the other USB controllers) ?
