but this is random behaviour. Sometimes the devices are detected and sometimes they are not.
This time after booting up i had inserted first the better usb drive(which does not give problems with detection and is mounted faster).
I again rebooted and tried insertion with the problematic pendrive into the usb hub. The system seems to have become ok now in that the problematic pendrive was also autodetected.
