using s3c2410-ohci and address 49 After this type of behaviour, the usb device will not be configured for any successive plug-out and plug-in or changing the ends. The device has to be rebooted so that the cable gets recognised the next time. can anyone please reply what may be going wrong is it from the hub driver or from the device specific driver ? what changes have to be done or where does the problem exactly lie?
