提供的操作系统内核版本:Linuxkunos 4.9.170 双网络通信正常,eth0eth1相互独立。 FTP数据传输速度正常,上传11M/s左右,下载10M/s左右。 file:///C:/Users/cfh/AppData/Local/Temp/msohtmlclip1/01/clip_image002.jpg file:///C:/Users/cfh/AppData/Local/Temp/msohtmlclip1/01/clip_image004.jpg
两路USB-HOST接口可以正常连接U盘,进行挂载后可以正常的进行文件传输。 [ 1991.274481] usb 1-1: new high-speed USBdevice number 2 using sunxi-ehci [ 1991.426235] usb-storage 1-1:1.0: USBMass Storage device detected [ 1991.434722] scsi host0: usb-storage1-1:1.0 [ 1992.446798] scsi 0:0:0:0:Direct-Access Generic Flash Disk 8.07 PQ: 0 ANSI: 4 [ 1992.458557] sd 0:0:0:0: [sda] 31457280512-byte logical blocks: (16.1 GB/15.0 GiB) [ 1992.468417] sd 0:0:0:0: [sda] WriteProtect is off [ 1992.473827] sd 0:0:0:0: [sda] ModeSense: 23 00 00 00 [ 1992.480819] sd 0:0:0:0: [sda] Writecache: disabled, read cache: enabled, doesn't support DPO or FUA [ 1992.502648] sda: sda1 [ 1992.509690] sd 0:0:0:0: [sda] AttachedSCSI removable disk [ 1992.770652] FAT-fs (sda1): Volume wasnot properly unmounted.
