Hello, This is regarding the MPC8323 in-built USB controller driver, Environment: LTIB: ltib-mpc832x_rdb-20070507 Linux: linux-2.6.20 In built usb driver is been ported from linux-2.6.30 to linux-2.6.20 (File: drivers/usb/host/fhci-hcd.c is been ported from kernel.org/linux-2.6.30) Problem description: File: "drivers/usb/host/fhci-hcd.c " In this file probe function: of_fhci_probe(struct of_device *ofdev, const struct of_device_id *ofid) is getting loaded successfully & FHCI Host Controller, interrupt and timer are getting registered File:"drivers/usb/host/fhci-hub.c" In this file function fhci_hub_status_data(struct usb_hcd *hcd, char *buf) is been polled continuosly, which is checking for the port change and port status of the our virtual hub using fhci->vroot_hub->port.wPortChange & fhci->vroot_hub->port.wPortStatus The value in this variable are not getting changed even after connecting & disconnection the device. We have manual checked the USBRXP pin, this pin is HIGH => when device is connected LOW => when device is not connected. Kindly let us know how should we debug/proceed.
