I want to isolate USB 2.0 OTG port of BF524 using ADuM4160, an usb isolator. USB OTG is high speed and ADuM4160 supports up to full speed.
Is there any way to restrict BF524 USB OTG to full speed?
If you're using the VisualDSP driver, the easiest way to force full speed is to connect the BF524 based product to the PC through a full-speed hub. This will force the BF524 to enumerate as a full-speed device.
If you're using your own driver then it's simply a matter of clearing the High Speed bit in the USB_POWER register and to make sure that endpoint descriptors indicate maximum packet sizes specific to full-speed transfers.
