As an aside, I found out that on my 2008 C2D MBP that you cannot put a USB-powered HD on a USB non-powered hub. There is just not enough juice. So, I always need to have a USB port free in order to plug an HD in.

I haven't actually tried mine with a USB powered hard drive, but Dr. Bott's T3Hub (non-powered) claims to support 1 high-power device along with 2 low-power devices. It does this by telling the computer it is a powered hub. http://www.drbott.net/product/3115-THSS/ Oh, and it comes with a short USB extension you can use with your 3G modem.

I'd test it with a hard drive for you, but I'm actually traveling right now and didn't bring it (more than happy to try it when I get home though). Only anticipated using two USB ports, one for the mouse and the other for a hard drive. 2nd hard drive will go on the FW800 port and I threw an SD card reader in the ExpressCard slot. I use a Cradlepoint router with an external battery for my 3G modem.
