本人最近想开发一下tiny6410的3G模块,特意买了一块华为E169外接3G模块。插上去之后发现,看打印信息显示,应该是加载进去了:
[root@FriendlyARM /]# usb 1-1.4: new full speed USB device using s3c2410-ohci and address 3usb 1-1.4: New USB device found, idVendor=12d1, idProduct=1001usb 1-1.4: New USB device strings: Mfr=1, Product=2, SerialNumber=1usb 1-1.4: Product: HUAWEI Mobileusb 1-1.4: Manufacturer: 每每每每每每每每每每每每每每每每每每每usb 1-1.4: SerialNumber: 每每每每每每每每每每每每每每每每每每每one_wire_status: 4option 1-1.4:1.0: GSM modem (1-port) converter detectedusb 1-1.4: GSM modem (1-port) converter now attached to ttyUSB0
此时,查看/dev下,有挂载ttyUSB0设备:
[root@FriendlyARM /]# ls /dev/ttyUSB0/dev/ttyUSB0[root@FriendlyARM /]#嬀/blockquote]但是使用自带的qtopia程序去连接时,打印信息出现: [root@FriendlyARM /]# option1 ttyUSB0: GSM modem (1-port) converter now disconnected from ttyUSB0option 1-1.4:1.0: device disconnected然后就连接失败了。这个时候,发现/dev下也没有了设备文件: [root@FriendlyARM /]# ls /dev/ttyUSB0 ls: /dev/ttyUSB0: No such file or directory [root@FriendlyARM /]#嬀猀:10]
在下新人一枚,有大神可以帮忙解答一下吗
