Use libusb or else use usbfs directly. Open the device file under /proc/bus/usb/ corresponding to the root hub of interest and use the USBDEVFS_CONTROL ioctl (or its equivalent) to send a Get-Port-Feature request for the port status. The same technique will work for any root hub -- and any external hub as well -- regardless of whether it is OHCI.
