usb powersaving mode?

[matt_max]

Hi guys,
After completing the last update (18.3) my NAS got some odd behavior. The front USB port switches off after a while. If I reboot NAS port works for a while. There is nothing in dmesg:

Code: Select all

[   23.906168] usb 1-1: new high-speed USB device number 2 using orion-ehci
[   24.107197] usb 1-1: New USB device found, idVendor=0e8d, idProduct=201c
[   24.116546] usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[   24.123665] usb 1-1: Product: Retroid Pocket 4 Pro
[   24.144170] usb 1-1: Manufacturer: Moorechip

[  359.181722] usb 1-1: USB disconnect, device number 2


I used it mainly to charge devices like phone on retroconsole. Now it is impossible.
echo "-1" > /sys/module/usbcore/parameters/autosuspend - do nothing
echo "on" > /sys/bus/usb/devices/usb1/power/control - nothing
Some kind of autosuspend? :thinking

I need to check but if I remember well no changes were made in the kernel wrt suspend usb power. I will double check

[fvdw]

checked kernel config but nothing changed on suspend kernel parameters. I will try if I can reproduce your issue.
After how many minutes does the power turns off ?

[fvdw]

I could not reproduce your behavior. From what I read suspend may be initiated by the usb device itself ?? (not sure about that)
I connected a mobile phone to the port to charge it and still charging after half hour aloso power remained on when the hard disk entered standby mode :dontknow

Hi

18.3 uses a new kernel image so I think it is worth to try to check if you still have the same behavior with the previous kernel version.

Then do

Code: Select all

plugout download-fw 5966

check if you have the same md5sum (2f791aece45389418973c103a88e64fb)

Code: Select all

md5sum /tmp/UIMAGE-414133-KIRKWOOD-1

And only if it is same value, overwrite the new kernel image on sda6

Code: Select all

dd if=/tmp/UIMAGE-414133-KIRKWOOD-1 of=/dev/sda6

Reboot only if you have no error with dd command.
