Re: USB troubles in rc2

Well, sorry, here is the info:

I think the problem is with the ohci_hcd:
____________________________________________________________________________________
With 2.6.8-rc2-mm2 (and even with bk-usb.patch reverted), my digital camera 
don't work in usb-storage mode nor ptp mode. My usb tablet don't work either. 
And I get this (even the camera is on, but it don't appear):

With 2.6.7-mm7 don't work either, but I can revert the bk-usb.patch in the 
andrew tree and all works ok. Even the camera:

So I think the changes went mainstream, so I don't have nothing to revert now. 
If any of you want me to try something, please ask me (CC me as I'm not 
subscribed).

Thanks.
