Can't mount Ext. HD from powered USB hub
iMac 2.66, 10.6.8
I've got an Iomega USB 2.0 128g SSD that I regularly clone my iMac to as a backup. When I plug it into the iMac directly, it mounts no problem and I can boot off it no problem. But when I plug it into my LinQ 7-port hub, it doesn't mount at all nor does it show up in Disk Utility. The LinQ works perfectly well with other devices.
Any ideas why this might be happening? Any ideas how I might force mount it?
