linux系统报错信息如下：

[30971.764840] phy1 -> rt2x00usb_vendor_request: Error - Vendor Request 0x07 failed for offset 0x0438 with error -71.[30975.519840] phy1 -> rt2x00usb_vendor_request: Error - Vendor Request 0x06 failed for offset 0x0408 with error -71.[30978.890840] phy1 -> rt2x00usb_vendor_request: Error - Vendor Request 0x06 failed for offset 0x0408 with error -71.[30982.389845] phy1 -> rt2x00usb_vendor_request: Error - Vendor Request 0x07 failed for offset 0x0438 with error -71.[30987.200842] phy1 -> rt2x00usb_vendor_request: Error - Vendor Request 0x07 failed for offset 0x101c with error -71.[30990.795843] phy1 -> rt2x00usb_vendor_request: Error - Vendor Request 0x07 failed for offset 0x101c with error -71.
    在使用外接无线网卡的时候，有时突然系统死机，且切换到其他tty也一直在报如上的错误，此时任何的操作都没有作用，这时候只要将外接的无线网卡拔掉，即可恢复正常。
