Can’t enable USB Drive in VirtualBox – troubleshooting help needed

Since mount a USB drive in Workstation I haven’t figured out how to grant “write” permission on the drive. I’ve tried all kinds of chmod, chown, chgrp commands. I researched a solution to install the utility “hdparm”, then ran the command hdparm -r0 /dev/sdb , but that didn’t work. The permissions didn’t change, and the USB is still read-only.

Any suggestions for a solution would be appreciated.
