[SI-LIST] Reg: USB OTG Controller

Hi All,

=20

   We are using ISP1761 USB 2.0 OTG controller and we have configured =
the
port 1 (OTG port) as peripheral controller. We are connecting PC to this
device. When we are connecting the PC in USB 1.1 port in our board we =
can see
the device id and all transfers in USB monitor but when we are =
connecting the
PC to USB 2.0 port the USB monitor is not giving the required =
information. I
am not sure whether the terminations and the filtering circuit for VBUS =
and
data lines we have given are correct or not. I have given below the =
circuit
for your understanding.

VBUS is coming 5.24V once we connected the PC

C150 is changed to 0.1uF, and then also it didn't work
