Subject: Re: [linux-usb-devel] usb_fill_bulk_urb() broken for USB1.1?

Hi Oliver

Usage:

	usb_fill_bulk_urb(macp->intr_urb, macp->usb,
		usb_rcvbulkpipe(macp->usb, EP_INT_IN),
		macp->IntEPBuffer, MAX_EPINT_BUFFER,
		zd1211_intr_cb, macp);

where

#define EP_INT_IN			0x03
#define MAX_EPINT_BUFFER	64

Here are the relevant structure definitions:

	struct usb_device	*usb;
	struct urb		*intr_urb;
	u8			*IntEPBuffer;

I can post the full structure if required.

Regards
Keith
