DM6467内核linux2.6.18,多张电信3G无线网卡不能同时使用
来源: 互联网 发布时间:2017-03-13
本文导语: 同时插多张联通3G无线网卡,设备可以正常的拨号,但是如果插多张电信3G无线网卡,就会出现拨一张电信卡后,就不能再往下拨下去了,会卡住。以下是拨通了第一张卡,再连着拨第二张卡出现的卡住的情况,还请...
同时插多张联通3G无线网卡,设备可以正常的拨号,但是如果插多张电信3G无线网卡,就会出现拨一张电信卡后,就不能再往下拨下去了,会卡住。以下是拨通了第一张卡,再连着拨第二张卡出现的卡住的情况,还请各位专家帮我看看,麻烦您们了!
下图是正常能拨号的情况:

用的是通用驱动usbserial吗?如果是的话,就在$KERNEL_SOURCE_DIR/drivers/usb/serial/generic.c这个文件中修改就可以了,即:
我们平时使用modprobe加载usbserial驱动时输入的vendor和product参数是传给usbserial_generic这个模块的。这里的调用过程是usb_serial_init()->usb_serial_general_register()。在这个函数中,在这里传入的参数:
generic_device_ids[0].idVendor = vendor;
generic_device_ids[0].idProduct = product;
generic_device_ids[0].match_flags = USB_DEVICE_ID_MATCH_VENDOR | USB_DEVICE_ID_MATCH_PRODUCT;
我们这里需要加入我们自己设备的vendor和product,因此在这行下面,我们需要加入:
// added by xzpeter, try to support both sim4100 and lc6311
// for sim4100
generic_device_ids[1].idVendor = 0x0456;
generic_device_ids[1].idProduct = 0x6532;
generic_device_ids[1].match_flags =
USB_DEVICE_ID_MATCH_VENDOR | USB_DEVICE_ID_MATCH_PRODUCT;
// for lc6311
generic_device_ids[2].idVendor = 0x1AB7;
generic_device_ids[2].idProduct = 0x6000;
generic_device_ids[2].match_flags =
USB_DEVICE_ID_MATCH_VENDOR | USB_DEVICE_ID_MATCH_PRODUCT;
// end here
