I would have thought that your device does have at least a one byte transmit/recieve buffer per end point. So can't you just write the driver as if it had a 1 byte FIFO?
I could send you a copy of my driver if you think it would help, but as I said it's not completely tested yet.

Hello,
I wanted to know if there are any controller driver already written for Gadget API, other than the netchip 2280 one? I've got problems with the usb_ep_queue function. The chip, I want to write the code for (Philips D12), has no FIFO inside, so either I have to make the usb_ep_queue not really as a queue function, but rather as a direct write function (which makes the driver not conform to the Gadget API doc), either I have to write a FIFO queue in the driver and a write function to the usb device controller at the end. Am I right? I hope that seeing driver code for other more "basic" chips could help me.
Thanks Miro
