今天在调试USB 网卡（rtl8152b）,直接插入USB网卡后，驱动正常插上网线正常通信，可以PING通路由器，也可以PING 外网；
但是中断加了个USB HUB后奇怪的事情发生了，网卡驱动貌似加载成功了，LSUSB也正常，ifconfig up 网卡也正常，手动分配IP也正常；
eth0 Link encap:Ethernet HWaddr 00:E0:4C:36:93:11
inet addr:192.168.31.123 Bcast:192.168.31.255 Mask:255.255.255.0

但是，就是PING不通路由器；
各位兄台有遇到此类问题不！
昨天收了，nano 发现SPI flas不是华邦W25Q128，是XT25Q128(国产芯片)。uboot 报错，内核启动失败；
最近W25Q128芯片涨价，所以发货时都使用XT的替换了
报FLASH不识别，ID为0b,40,18
修改uboot
u-boot/drivers/mtd/spi/u-boot/drivers/mtd/spi/spi_flash_ids.c
{"w25q128bv", INFO(0xef4018, 0x0, 64 * 1024, 256, RD_FULL | WR_QPP | SECT_4K) },
+{"xt25q128", INFO(0x0b4018, 0x0, 64 * 1024, 256, RD_FULL | WR_QPP | SECT_4K) },
修改内核源码下的 ./drivers/mtd/spi/spi-nor.c
{ "w25q128", INFO(0xef4018, 0, 64 * 1024, 256, SECT_4K) },
+{ "w25q128", INFO(0xef4018, 0, 64 * 1024, 256, 0) },
+{ "w25q128", INFO(0xef4018, 0, 64 * 1024, 256, 0) },
重新编译下载OK；
哪位大神帮看一下，U盘与USB 网卡插上去一点反映也没有，LSUSB，输出“Bus 001 Device 001: ID 1d6b:0002”
dts配置以下：
&usb_otg {
dr_mode = "otg";
status = "okay";
};
&usbphy {
usb0_id_det-gpio = <&pio 4 2 GPIO_ACTIVE_HIGH>; / PE2 /
status = "okay";
};

荔枝派F1C100S，我启动好像是正常的，OTG功能，USB插入电脑有反映WIN可以驱动加载，但是HOST功能一直不行
我插入U盘、USB网卡都没反映，lsus，出来一直具返回一行“Bus 001 Device 001: ID 1d6b:0002”；
我看PE2，插入电脑高电压，插U盘是低电压，理论是对的
