Hi.

Im attempting to get the USB function on the TC6393XB (Toshiba multi-io chip) working. 
This chip is used in their PDAs, including the e740, e750, and e800.

I have register documentation for the chip but it is very sparse, however I can bring 
up the USB and have OHCI registers in memory which seem to make sense, and respond to 
plug/unplugging.

I cannot see any interrupt activity at all, which I suspect is the major problem.

I know little of USB hosts, so Im a bit lost on where to start now.

The register set is OHCI.

is there a way to provoke interrupts from an OHCI chiip? I need to be able to generate 
interrupts reliably so that I can work out how to set up the chips interrupt masking / 
routing.

further, the chip has an on-board 32k buffer which the documentation suggests must be 
used to send data to / from the device (td/eds ?) but it makes little mention of 
wether the chip can handle DMA or anything else. I suspect it cannot.

I have based my driver on the sa1111 driver and it seems able to attach to the chip 
and produce sane output in /sys

TIA.
