  1. 1) Ops, i've seen that script.bin it is symlink and decided rewrite original. I will change post. 2) I don't think so. I'm used this dongle on many device. it can work fine one month or can freeze in first day. If I'm not mistaken it consumes ~ 100 mA
  2. If you knew how Huawei sounds and what it means in Russian, you would understand why it freeze after few days . Something like "piece of .... " but worse It works normal only as VoIP gateway on asterisk(more than 1 year uptime). I've seen same problem on routers, desktop pc and now here. I think it is modem hardware or software problem.
  3. Thank you very much tkaiser! Thank you all! Works great! Problem solved! Message to descendants : 1) Taking out of control of the respective driver # cd /boot # bin2fex ./bin/orangepione.bin > newbin # nano ./newbin Change line 'usb_drv_vbus_gpio = port:PL02<1><0><default><0>' on 'usb_drv_vbus_gpio = ' # rm ./script.bin # fex2bin ./newbin > script.bin # rm ./newbin !REMEMBER! - after reboot power on USB OTG port will be OFF by default! # reboot 2) Export gpio pin PL02. To obtain the correct number you have to calculate it from the pin name. Use this formula: (position of letter in alphabet - 1) * 32 + pin number (HL02) letter L - stay on 12 position in alphabet. (HL02) pin number - 2 result: (12-1)*32+2=354 Use GPIO sysfs do next: # echo 354 > /sys/class/gpio/export # echo "out" > /sys/class/gpio/gpio354/direction Power ON # echo 1 > /sys/class/gpio/gpio354/value Power OFF # echo 0 > /sys/class/gpio/gpio354/value Enjoy!
  4. It's very interesting, what i need to do to "pull this trigger"? Restart is acceptable but helpless after # reboot modem still frozen
  5. Yes, I read it and even tried this: orangepi PH26<1><0><default><0> PH22<1><0><default><0> It is necessary to cut the wire 5V in the OTG cable and connect via a relay Last chance. Thank you tkiser for your fast and useful respond.
  6. Hello friends! I Am using 3G modem(Huawei E171 connected by OTG cable) on my OPi One for internet, but one problem - modem after few days working freeze. Reboot don't help because not full power off on USB, and after reboot i don't see modem in /dev. Only after physical remove modem and install again it's initialized and work fine. Question: Can i power off USB from cli? # uname -a Linux orangepione 3.4.113-sun8i #18 SMP PREEMPT Thu Jun 15 02:16:06 CEST 2017 armv7l armv7l armv7l GNU/Linu # lsusb Bus 008 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 004 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 002: ID 0bda:8179 Realtek Semiconductor Corp.
