#Lsusb modem missing tty ports code
CPU: div instructions available: patching division code CPU: ARMv7 Processor revision 4 (ARMv7), cr=10c5383d i changed and tested some options like "baud rate" "number of pins" but couldn't identify the problem. when i run "screen" command, like: "screen /dev/ttyACM1 9600,cs8", nothing happened. now, when i connect the device to my pi, both ports is bond to ACM0 and ACM1. i used Cypress usb-serial configuration utility and changed SCB0 and SCB1 from I2C and SPI to UART-CDC. Store it to /etc/udev/rules.d/70-huawei_les for example.įilename /etc/udev/rules.d/70-huawei_e352.Recent changes happened. If you don't want to impress people by remembering these cryptic lines, you could write two udev rules to execute these commands whenever the device isĪdded to the USB subsystem. The modem should be usable by now and your network-manager should ask you for the PIN to unlock the device. usb 2-5: new high speed USB device using ehci_hcd and address 12 option 2-5:1.0: GSM modem (1-port) converter detected usb 2-5: GSM modem (1-port) converter now attached to ttyUSB0 option 2-5:1.1: GSM modem (1-port) converter detected usb 2-5: GSM modem (1-port) converter now attached to ttyUSB1 option 2-5:1.2: GSM modem (1-port) converter detected usb 2-5: GSM modem (1-port) converter now attached to ttyUSB2 option 2-5:1.3: GSM modem (1-port) converter detected usb 2-5: GSM modem (1-port) converter now attached to ttyUSB3 option 2-5:1.4: GSM modem (1-port) converter detected usb 2-5: GSM modem (1-port) converter now attached to ttyUSB4 option 2-5:1.5: GSM modem (1-port) converter detected usb 2-5: GSM modem (1-port) converter now attached to ttyUSB5
