1. Summary: Loading the usb-ohci module (or ehci-hcd with a usb 2.0 hub
attached) causes incomplete frames to be received when capturing dv from the
firewire controller.
2. Full description: Whenever the usb-ohci or ehci-hcd modules are loaded as
mentioned in 1., dvgrab reports constantly that the ieee1394 driver received
an incomplete frame. If I unload the usb-ohci module (or load the ehci-hcd
module without a hub attached), the problem no longer occurs. This happens
whether or not any usb devices are connected to the controller. Forgive me
for the following but, I installed winblows on this machine just to test and
see if it was a hardware problem. Everything works fine under winblows so...
it doesn't appear to be a problem with the hardware.

8. Workarounds: If I remove the usb-ohci module and capture dv from a console
(without X running) the problem goes away. As soon as I load the usb-ohci
module (or connect a usb 2.0 hub with the ehci-hcd module loaded), dvgrab
immediately begins printing messages about incomplete frames.
Thanx in advance for any help that can be provided.
