Ubuntu linux does not see usb drive

Bit poster
I have Ubuntu 13.10 installed in a vm under Parallels Desktop 9 on a MBP running OS X 10.7. I have attached a usb drive. It is formatted FAT32. The drive appears under the Parallels usb icon. But I cannot find it under Ubuntu. When I run dmesg in Ubuntu the last message is: "scsi 14:0:0:0: Device offlined - not ready after error recovery".

If I associate the drive with OSX I can access with no issues.

What I want to do is be able to reformat the drive under linux to ext.

Also, I have been successful mounting a sd card in the Ubuntu VM.

Any guidance is greatly appreciated.
 
I have been doing some additional debugging.

I select the drive from the usb list in Parallels. There is a green flash under the usb symbol at bottom of window.
Then I run dmesg in a terminal window and show the following:

[ 1820.154166] usb 1-2: new high-speed USB device number 6 using ehci-pci

[ 1849.874509] scsi 11:0:0:0: Device offlined - not ready after error recovery

Any ideas on why the device is off lined?
 
I have been doing some additional debugging. I tried a different external drive which is older and USB 2. Ubuntu saw the drive and auto mounted it. So I tried connecting the new drive, which is USB 3/2, through a usb hub which is USB 2. Now Ubuntu sees and auto mounts the device.

Now my issue is that both drives are auto mounted as read only. I have amount, mount -rw and it still mounts as ro.

Any pointers
 
I have an Laclie rugged USB 3.0 1.5TB drive. See same issue if plugged into usb 2.0 hub
if plugged directly into the mac cannot get the VM to accept the device. trying to move the drive from the mac to parallels VM always fails.
Tried ubuntu 12.04, 13.02 and 10.04
