yes, mpc8270 with Philips 1561
(I found the CPM USB host controller with 1 ms SOF
under software control too risky)
the 1561 is OHCI/EHCI compliant, the standard linux drivers
can be used

i still can't figure out is it a hardware or configuration problem,
i can see all registers, drivers seems to work,
it can detect device insert
but there is no data transmision
there are also no interrupts,
i'm not sure what to write in interrupt_line in PCI config space
any hints?

What kernel version do you use?
In a 2.4 series kernel, you might check m8260_pcibios_fixup()
and probably set dev->irq ?
I don't know yet if this is the same in 2.6. I recently saw a lot of
pci setup related changes in this mailing list.

i'm using 2.4.19 and 2.4.25 usb code
irqs, and io maps are set correctly
when trying to use ohci code there is one interrupt at startup:
<3>usb-ohci.c: OHCI Unrecoverable Error, controller usb-00:1e.0
anyone knows, what does it mean?
i've modified code to ignore it...
