only work
at full speed i.e. whatever is the connected device, the bandwidth
should be 12MB.
I thought i could perform it just by setting some registers to right
value but it
aren't working. I fear i have to force software to always use TT and split transfer
but i dont
know exactly where to start.. =20 If anybody could help, would be so great!!
Your question can be interpreted as how to force EHCI host driver to work in full speed. Usb-devel list cc'ed should be a better place for such a question. - Leo
