System reboots unexpectedly after usb power-reset on Rb2011

RouterOS General
1

on occassion (lets say every 3rd day) doing a

/system routerboard usb power-reset duration=10s

for a 3G usb modem reset, makes the entire system reboot unexpectedly with no autosupout file created for it.

currently on RoS 5.24, latest firmware too.

Any ideas? I can rerun it myself many times, and wont get the failure, but now since I’m doing doing remote logging, I can see this problem is related to the usb reset in a script of mine. If I omit the reset command it never happens. (So the bug, is either that a ppp-out for a 3g is changing to running state is causing the issue, or, the usb power-reset is causing the issue)

What if you change the script so that it disables ppp-out interface, sleep 10 seconds, do usb power reset, sleep 10 seconds, enable ppp-out

Hi Petter,

(I agree, perhaps I should do this for better safety etc as opposed to just cutting it off).

I’ll make this change and see what happens over the next few days.

May I ask how you connect the 3G usb device to the rb2011? (Where did you find a cable with micro usb male in one end and regular usb female in the other?)

hi the forums are full of parts explaining this.
