I'm designing IMX27L as a device with WINCE OS.In my existing design, I am using ISP1507 for USB Transceiver on IMX27L OTG port without any connection issue. Due to EOL of ISP1507, I had changed my USB Transceiver to USB3311. Now my IMX27L having lost connection to the host after doing few rebooting cycles. Do we need to update the software portion since I changed the USB Transceiver? What criteria do I need to look at for the connection wise?
