Hello,
There hadn't been discussions this forum and these matters recent time.
I follow the instructions in KB 2097401 in order to attach physical USB pen drive to virtual machine in raw mode.
Bootable USB is targeted, the creation process includes changes in MBS, therefore I think the VM needs access
to whole physical drive, not only to particular partition. The process of creating bootable usb drive uses Linux scripts
therefore can't be accomplished on OS X host.
Actually it is card-reader SD-only USB 3.0, Sandisk - no idea if this concerns - with one partition formatted to FAT32 on it.
Partitioning scheme - DOS.
All this is made in following env. Fusion Pro 8.0 on OS X 10.9. Client system is Ubuntu current LTS.
OS X user accomplishing this task does not carry the administrator rights. It is Standard user.
Following steps were completed on host
Insert pen drive into Mac USB port
The assigned /dev/diskX found out
Partition unmount, drive no eject ( host OS X Disk Utility )
su admin
sudo chmod o+rwx // as originally ls -alh reads brw-r-----
exit // back to Standard user
/Applications/VMware\ Fusion.app/Contents/Library/vmware-rawdiskCreator create /dev/disk2 fullDevice vms/U01/U01.vmwarevm/usbpenraw ide
Adapt VM's .vmx file according to elaborations in KB
sata1:0 used and not conflicting with old entries over there
Start VM
Check availability to USB pen from guest using Ubuntu GUI Disks app
Results: USB pen drive not presented, also if to use GParted.
For any hints thanks in advance.
