This is based on reverse-engineering and examination of the packet + * data sent and received by the WinXP driver using USBSnoopy. Feel free to + * update here as more of this dongle is known: + * + * General: Unlike the other USB IrDA dongles, this particular dongle exposes, + * not two bulk (in and out) endpoints, but two *interrupt* ones. This dongle, + * like the bulk based ones (stir4200.c and mcs7780.c), requires polling in + * order to receive data. + * Transmission: Just like stir4200, this dongle uses a raw stream of data, + * which needs to be wrapped and escaped in a similar way as in stir4200.c. + * Reception: Poll-based, as in stir4200. Each read returns the contents of a + * 8-byte buffer, of which the first byte (LSB) indicates the number of bytes + * (1-7) of valid data contained within the remaining 7 bytes. For example, if + * the buffer had the following contents: + * 06 ff ff ff c0 01 04 aa + * This means that (06) there are 6 bytes of valid data. The byte 0xaa at the + * end is garbage (left over from a previous reception) and is discarded. + * If a read returns an "impossible" value as the length of valid data (such as + * 0x36) in the first byte, then the buffer is uninitialized (as is the case of + * first plug-in) and its contents should be discarded. There is currently no + * evidence that the top 5 bits of the 1st byte of the buffer can have values + * other than 0 once reception begins. + * Once valid bytes are collected, the assembled stream is a sequence of + * wrapped IrDA frames that is unwrapped and unescaped as in stir4200.c. + * BIG FAT WARNING: the dongle does *not* reset the RX buffer in any way after + * a successful read from the host, which means that in absence of further + * reception, repeated reads from the dongle will return the exact same + * contents repeatedly. Attempts to be smart and cache a previous read seem + * to result in corrupted packets, so this driver depends on the unwrap logic + * to sort out any repeated reads. + * Speed change: no commands observed so far to change speed, assumed fixed + * 9600bps (SIR). + */ + +#include <linux/module.h> +#include <linux/moduleparam.h> +#include <linux/kernel.h> +#include <linux/types.h> +#include <linux/errno.h> +#include <linux/init.h> +#include <linux/slab.h> +#include <linux/module.h> +#include <linux/kref.h> +#include <linux/usb.h> +#include <linux/device.h> +#include <linux/crc32.h> + +#include <asm/unaligned.h> +#include <asm/byteorder.h> +#include <asm/uaccess.h> + +#include <net/irda/irda.h> +#include <net/irda/wrapper.h> +#include <net/irda/crc.h> + +/* + * According to lsusb, 0x07c0 is assigned to + * "Code Mercenaries Hard- und Software GmbH" + */ +#define KING_VENDOR_ID 0x07c0 +#define KING_PRODUCT_ID 0x4200 + +/* These are the currently known USB ids */ +static struct usb_device_id dongles[] = { + /* KingSun Co,Ltd IrDA/USB Bridge */ + { USB_DEVICE(KING_VENDOR_ID, KING_PRODUCT_ID) }, + { } +}; + +MODULE_DEVICE_TABLE(usb, dongles); + +#define KINGSUN_MTT 0x07 + +#define KINGSUN_FIFO_SIZE 4096 +#define KINGSUN_EP_IN 0 +#define KINGSUN_EP_OUT 1 + +struct kingsun_cb { + struct usb_device *usbdev; /* init: probe_irda */ + struct net_device *netdev; /* network layer */ + struct irlap_cb *irlap; /* The link layer we are binded to */ + struct net_device_stats stats; /* network statistics */ + struct qos_info qos; + + __u8 *in_buf; /* receive buffer */ + __u8 *out_buf; /* transmit buffer */ + __u8 max_rx; /* max. atomic read from dongle + (usually 8), also size of in_buf */ + __u8 max_tx; /* max. atomic write to dongle + (usually 8) */ + + iobuff_t rx_buff; /* receive unwrap state machine */ + struct timeval rx_time; + spinlock_t lock; + int receiving; + + __u8 ep_in; + __u8 ep_out; + + struct urb *tx_urb; + struct urb *rx_urb; +}; + +/* Callback transmission routine */ +static void kingsun_send_irq(struct urb *urb) +{ + struct kingsun_cb *kingsun = urb->context; + struct net_device *netdev = kingsun->netdev; + + /* in process of stopping, just drop data */ + if (!netif_running(kingsun->netdev)) { + err("kingsun_send_irq: Network not running!"); + return; + } + + /* unlink, shutdown, unplug, other nasties */ + if (urb->status != 0) { + err("kingsun_send_irq: urb asynchronously failed - %d", + urb->status); + } + netif_wake_queue(netdev); +} + +/* + * Called from net/core when new frame is available. + */ +static int kingsun_hard_xmit(struct sk_buff *skb, struct net_device *netdev) +{ + struct kingsun_cb *kingsun; + int wraplen; + int ret = 0; + + if (skb == NULL || netdev == NULL) + return -EINVAL; + + netif_stop_queue(netdev); + + /* the IRDA wrapping routines don't deal with non linear skb */ + SKB_LINEAR_ASSERT(skb); + + kingsun = netdev_priv(netdev); + + spin_lock(&kingsun->lock); + + /* Append data to the end of whatever data remains to be transmitted */ + wraplen = async_wrap_skb(skb, + kingsun->out_buf, + KINGSUN_FIFO_SIZE); + + /* Calculate how much data can be transmitted in this urb */ + usb_fill_int_urb(kingsun->tx_urb, kingsun->usbdev, + usb_sndintpipe(kingsun->usbdev, kingsun->ep_out), + kingsun->out_buf, wraplen, kingsun_send_irq, + kingsun, 1); + + if ((ret = usb_submit_urb(kingsun->tx_urb, GFP_ATOMIC))) { + err("kingsun_hard_xmit: failed tx_urb submit: %d", ret); + switch (ret) { + case -ENODEV: + case -EPIPE: + break; + default: + kingsun->stats.tx_errors++; + netif_start_queue(netdev); + } + } else { + kingsun->stats.tx_packets++; + kingsun->stats.tx_bytes += skb->len; + } + + dev_kfree_skb(skb); + spin_unlock(&kingsun->lock); + + return ret; +} + +/* Receive callback function */ +static void kingsun_rcv_irq(struct urb *urb) +{ + struct kingsun_cb *kingsun = urb->context; + int ret; + + /* in process of stopping, just drop data */ + if (!netif_running(kingsun->netdev)) { + kingsun->receiving = 0; + return; + } + + /* unlink, shutdown, unplug, other nasties */ + if (urb->status != 0) { + err("kingsun_rcv_irq: urb asynchronously failed - %d", + urb->status); + kingsun->receiving = 0; + return; + } + + if (urb->actual_length == kingsun->max_rx) { + __u8 *bytes = urb->transfer_buffer; + int i; + + /* The very first byte in the buffer indicates the length of + valid data in the read.
