This is a very basic explanation from a person with very minimal knowledge on the topic. But from what I understand the usb device sends a signal when plugged in. So you plug in your USB hub and no devices are plugged in when the signal is sent thus no drives are mounted. Now when you plug a drive into the hub a signal is sent, but it stops at the hub and never makes it to the client, so no drive is mounted. If you plug the drive into the hub, then plug the hub into the client, there is a drive present when the signal is sent so the drive is mounted. I think Scott Balnaeves said that you could possibly probe the usb device every so often to see if a drive was present, but I can't exactly remember. If you contact him I'm sure he'll shed a great amount of light on what is happening.
