I recently switched over to a different computer in my development and
it uses the OHCI driver and I have to unplug the device several times
before it works. Lookin @ system log, it has problems reading
descriptors, accepting new addresses, etc. Since I have a iFP-790T
(USB2.0), I bought a USB2.0 PCI card and I have not had one problem
connectiing it to either a EHCI controller (usb2.0) or a UHCI
controller (most intel and via).
So if you usb hub uses the ohci_hcd driver, there might be some sort
of problem there....
