I only have a HUB with a Mini-USB-Input and a cable Mini-USB-B to (usual) USB-A. The connector on the board also is a Mini-A/B-Port, so i would need a Mini-USB-(AorB)--to--Mini-USB-B--cable. Maybe with OTG capability and an USB-HUB with OTG capability. > > If necessary, I could try to order one or solder one by 2 old Mini-USB-cables. > > But you could try my above suggestion #2 which is unbind wired USB HUB > from its driver. You are right, I'm sorry, I misunderstood your word "wired", I thought you were talking about the Hub i should connect to Mini-USB-OTG, not the soldered one on the board. I did so right now, the abnormal wakeup occurs. Also echo -n "1-0:1.0" > /sys/bus/usb/drivers/hub/unbind doesn't change the abnormal wakeup. Note: I previously enabled all wakeup devices as always. This is the content of the hub directory: root@emtrion-mx6:/sys/bus/usb/drivers/hub# ls -l lrwxrwxrwx 1 root root 0 Mar 1 09:23 1-0:1.0 -> ../../../../devices/soc0/soc/2100000.aips-bus/2184200.usb/ci_hdrc.1/usb1/1-0:1.0 lrwxrwxrwx 1 root root 0 Mar 1 09:23 1-1:1.0 -> ../../../../devices/soc0/soc/2100000.aips-bus/2184200.usb/ci_hdrc.1/usb1/1-1/1-1:1.0 --w------- 1 root root 4096 Mar 1 09:23 bind lrwxrwxrwx 1 root root 0 Mar 1 09:23 module -> ../../../../module/usbcore -rw-r--r-- 1 root root 4096 Mar 1 09:23 new_id -rw-r--r-- 1 root root 4096 Mar 1 09:23 remove_id --w------- 1 root root 4096 Mar 1 09:23 uevent --w------- 1 root root 4096 Mar 1 09:23 unbind I've noticed that there is no response on unbindung 1-1:1.0, but on unbinding 1-0:1.0: echo -n "1-1:1.0" > /sys/bus/usb/drivers/hub/unbind <empty line> <empty line> echo -n "1-0:1.0" > /sys/bus/usb/drivers/hub/unbind [ 212.373519] usb 1-1: USB disconnect, device number 2 <empty line> <empty line> The 2nd one removes /sys/devices/soc0/soc/2100000.aips-bus/2184200.usb/ci_hdrc.1/usb1/1-1/ directory. And this time, I enabled everything remaining after unbinding both --> it still shows abnormal wakeup behaviour. I've got a meeting in a few minutes. I will continue later.
