Just a simple me, too. I've got the problem with a TerraCAM USB Pro. Plugged 
into my Apple Keyboard it works (with a warning about high power 
consumption). But if I plug it into my Belkin F5U237 the driver complains 
with: "drivers/usb/media/ov511.c: init isoc: usb_submit_urb(0) ret -38".

Have you already tried another USBv2 hub?

Cheers,

PS: I'm using a ASUS P4C800deluxe and Linux 2.6.9
