Does Linux support more than 2TB on a USB attached device?

Hi,

I hope that this is not an oft repeated question, but recently during
testing we encountered the following errors:

Oct  2 18:43:12 red-gemini mail-notification: No worthy mechs found
Oct  2 18:45:55 red-gemini kernel: sd 7:0:0:0: [sdb] Very big device.

I think we were returning 0x67FFFFFFF as the max LAB in the READ
CAPACITY(16).

Is there something special we need to enable in Linux to allow for more
than 2TB on a USB device?
