How to reset USB bus?

Jerry · October 5, 2017, 5:41pm

Hi all, is it possible to reset USB bus without restarting the device ? I have on my Omnia USB dongle for turris gadgets and USB TV tuner - both stop working after few days. Plug out and plug in don’t help only Omnia restart. Load is 3.00 and “lsusb” shows nothing and freezes … nothing in system log

… dmesg | grep usb
[135509.823980] usb 4-1: USB disconnect, device number 2
[135509.823997] usb 4-1.2: USB disconnect, device number 3

[138753.609713] usb 5-1: new SuperSpeed USB device number 4 using xhci-hcd

any advice what to try or how to debug ? Haven’t restarted yet and trying to solve it without restart …

Thanks in advance

usbreset PPPP:VVVV - reset by product and vendor id
usbreset BBB/DDD - reset by bus and device number
usbreset “Product” - reset by product name

Thanks, but it seems to reset USB devices and I need to reset or reinicialize Omnia’s USB bus or driver without rebooting the Omnia if it is possible…

root@Omnia:~# lsusb - show nothing and freezes

root@Omnia:~# usbreset
Usage:
usbreset PPPP:VVVV - reset by product and vendor id
usbreset BBB/DDD - reset by bus and device number
usbreset “Product” - reset by product name

Devices:
Number 001/002 ID 05c6:9215 Quectel LTE Module
Number 002/002 ID 7392:7811 802.11n WLAN Adapter

here should be 2 more devices - Jablotron dongle and TV tuner
but terminal again freezes

I had been using both devices on Turris 1.0 for a lot of months, but few months ago USB started to stop working few days after reboot … so I moved both to Omnia and again few weeks maybe months all was OK, but now it stops working again after few days …

I will start debuging by removing one device and leaving another one … we will see

maybe try to remove the usb modules with rmmod and then load again with modprobe (or insmod).

root@kukuzi:~# lsmod |grep usbcore
usb_common              2381  1 usbcore
usbcore               128799 29 qcserial

Thanks - I will try next time …

lsusb output after reboot :

root@Omnia:~# lsusb

here we can see that Bus 001 and 002 were OK and Bus 003, 004, 005 was not working …

so any new code in kernel regarding USB bus ? No need to remove usb device …

I have the same problem with my USB HDDs.
I connect them at evening and they have /dev/sdc and /dev/sdd.
But they have /dev/sde and /dev/sdf in the morning. And also they are unmounted. I was able to mount one them.
I have to reboot Turris 1.0 to connect second one.

PS: This happens each night. hd-idle is not enabled. And also I was coping from one of these HDD during whole night and even that they disconnect. Because of that copying failed.

Is there any solution for this USB issue?

I have Turris Omnia and both USBs are unstable and HDDs disconnects after some time. I encounter this issue in the past and then my turris have one year pause in the paper box (due to house reconstruction) but it didn’t grow up. Possible HW issue?

What is package for usbreset? It seems I don’t have it included.

Thanks
