no sir.. it was configured since i added a usb device in the settings PLUS my usb drive was read when i started the VM-> removable devices -> USB

and the var log messages was able to read the name of my flash drive. .

I didn't read your initial message close enough. I meant to change my post latter but got interrupted.

Your system is recognizing the drive, and I don't see errors posted.
Try looking at the output of "sudo /usr/sbin/rchal status". If you did see a device, but it wouldn't mount, I would think that one possibility is the the kde media manager wasn't running.

You might look at the output of "lsmod | grep hci". If one of the usb modules is missing that could be the cause of the problem. I don't remember which is which among ohci_hcd, ehci_hcd and uhci_hcd. One is for USB1.0, the others are for USB2.0 but I think it depends on your hardware which is used.

tried it with VL 5.8 -- no problem encountered. . il try your suggestion jschiwal..thanks

/usr/sbin/rchal status ------- RUNNING

lsmod | grep hci :
