Re: [linuxppc] 2.6.12-3 header <asm/usb.h> missing ?

Kumar,

thanks for the Info, that helps. Do you know if in this kernel Version 
the MPC5200 USB Bug is already handled?

I refer to errata document MPC5200E.pdf (I think rev. 06/2005) in which 
its stated that the frame_no and pad1 words are swapped in the 
processors OHCI Area. I saw in some earlier 2.4 kernel that in 
/drivers/usb/host/ohci.h the members frame_no and pad1 of struct 
ohci_hcca were swapped. maybe thats not necessary anymore ?

Im using this driver to support our embedded system modules equipped 
with the 5200 (see the EM1 board on www.men.de for specs).

regards,
Thomas
