USB host controller这样正常启动了么？

int __init pcibios_map_irq(struct pci_dev *dev, u8 slot, u8 pin) {     u8 intr = 0;     printk("pcibios_map_irq: %02x %02x\n", slot, pin);     /* This should be how its done but our boards are      * wired a bit different so hardcode the interrupt      * after this.      */     switch(pin)     {         case 1: intr = IAD_IV_HI0; break;         case 2: intr = IAD_IV_HI1; break;         case 3: intr = IAD_IV_HI2; break;     }     /* now for hardwire */     /* TODO: need to check other boards to make sure all are      * set to use HI2 intr      */     intr = IAD_IV_HI2;     pci_write_config_byte(dev, PCI_INTERRUPT_LINE, intr);     return intr; }

上面是这个程序在开机的时候显示把slot与pin所有组合打印出来了，pci_write_config_byte写入中断线，IAD_IV_HI2的值是0x0B即11，即把所有PCI设备中断号都设置为11？？但是我的pci usb host controller的中断线的那个字节是只读的，那这个函数是不是就是对我的设备没有影响了？

看这个日志的记录，好像没有什么错误的地方，但是我插个读卡器没有任何反应，mount /dev/sda1 /mnt 显示没有此设备。而读卡器连灯也没有亮，是驱动的问题还是读卡器的问题？
还有附件是手册里的一段话，不是很明白，希望高手讲解
