4 years ago OK I am now running the trace but as I said it can be hours or days before it will crash. We run this software on many pis and see the same issue so it is not just the one I am developing on. If there is a way to restart the USB hub via a command that would be great. Then I can issue that if I detect that I can no loger connect to the USB devices.

4 years ago I will stop / start the Trace every now and then until it fails so the trace file is not that big
P33M
commented
4 years ago The trace is recorded to a ring buffer - oldest entries are evicted, so if you are able to intervene soon after an anomaly occurs, there is a good chance that it will span what happened either side of the event.
JacoFourie
commented
4 years ago OK so I managed to get the crash again.
If I look in the trace file all is normal showing this.
Then after the crash I see this.
After a lsusb this is what I see
Here is a link to the trace file.

4 years ago This should fully reset the XHCI controller but if the attached devices are in a bad state it won't necessarily resolve the issue i.e. it might be better to reboot on failure
echo 1 >/sys/bus/pci/devices/0000:00:00.0/remove sleep 2 echo 1 >/sys/bus/pci/rescan

4 years ago It would be useful to see what state the PCIe link is in when Linux decides that the xhci controller is dead. In the dead state, does sudo lspci -vvv return output for the VLI controller?
JacoFourie
commented
4 years ago Hi. I have no idea. What commands should I type when it is dead, 'sudo lspci -vvv' ? Then I will share the output. I will have to wait for it to crash again as I rebooted the PI.

4 years ago When the controller is in the dead state, capture the output of lspci first, before trying to do the rescan sequence.

4 years ago I think you need to do 'sudo su' and run the reset parameters from a root shell
pelwell
commented
4 years ago Try either:
$ sudo sh -c "echo 1 > /sys/bus/pci/devices/0000:00:00.0/remove"
$ sudo sh -c "echo 1 > /sys/bus/pci/rescan"or
$ echo 1 | sudo tee /sys/bus/pci/devices/0000:00:00.0/remove
$ echo 1 | sudo tee /sys/bus/pci/rescanUnless you take one of the three approaches above, the echo command runs as root but the output of the command is still written to the /sys pseudo-files by the current shell, which is probably running as pi.

4 years ago $ sudo sh -c "echo 1 > /sys/bus/pci/devices/0000:00:00.0/remove" $ sudo sh -c "echo 1 > /sys/bus/pci/rescan"
OK great. That works and I am able to get the USB back and all works again without a reboot. WOW OK that is great, thanks so much. Why does the USB stop working ??
JacoFourie
commented
4 years ago This time it took 2 days before it crashed. The commands got it back again. Why would id do this? Is it hardware power or software? Will these commands work on every PI 4,3 and zero? Is it always the same command (can I hardcode it) or do I need to find what to remove first?
JacoFourie
commented
4 years ago Hi. I have the same issue on the Pi 3. What are the same commands to remove and rescan the bus like on the 4 as these commands don't seem to work on the 3? Also, I Will need for the 2 and Zero just in case.
JacoFourie
commented
4 years ago I see there are /sys/bus/devices folders.
So I tried my luck with. But it does not work.
sudo sh -c "echo 1 > /sys/bus/usb/devices/remove" sudo sh -c "echo 1 > /sys/bus/usb/rescan"
JacoFourie
commented
4 years ago I found this script but it wont work as lsusb brings back nothing. I need to reset the full system not just one device and then rescan for new devices.
set -euo pipefail IFS=$'\n\t'
#edit the below tow lines of vendor and product values using lsusb result
dev=$(lsusb -t | grep usbdevicename | grep 'If 1' | cut -d' ' -f13|cut -d"," -f1)
#VENDOR=05a3
#PRODUCT=9230
VENDOR=$(lsusb -s $dev | cut -d' ' -f6 | cut -d: -f1)
PRODUCT=$(lsusb -s $dev | cut -d' ' -f6 | cut -d: -f2)
for DIR in $(find /sys/bus/usb/devices/ -maxdepth 1 -type l); do
if [[ -f $DIR/idVendor && -f $DIR/idProduct &&
$(cat $DIR/idVendor) == $VENDOR && $(cat $DIR/idProduct) == $PRODUCT ]]; then
echo 0 > $DIR/authorized
sleep 0.5
echo 1 > $DIR/authorized
fi
donePi 1-3 use a completely different controller architecture. You can "rescan" the USB bus on a Pi 3 by forcing a disconnect/reconnect via
# echo 0 > /sys/devices/platform/soc/3f980000.usb/buspower
# echo 1 > /sys/devices/platform/soc/3f980000.usb/buspowerNote that the node address changes between BCM2835 and BCM2836/7.
JacoFourie
commented
4 years ago @P33M thank you. What do you mean by "Note that the node address changes between BCM2835 and BCM2836/7."
JacoFourie
commented
4 years ago Also if I use this command I lose network connection.
P33M
commented
4 years ago The 3f980000.usb directory turns into 20980000.usb on Pi 0/1. You will temporarily lose the ethernet adapter on Pi 1-3 as it's connected via USB, but wireless and Pi 4 ethernet will be unaffected.
In practice, network protocols that don't send data during the bus reset typically survive - ssh sessions usually remain open.

3 years ago I am using a RPB4 to boot loop test a USB-unit and has encountered the exact same problem. After about 1 day lsusb yields the following:
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hubThe two commands seems to fix it for me to:
$ sudo sh -c "echo 1 > /sys/bus/pci/devices/0000:00:00.0/remove"
$ sudo sh -c "echo 1 > /sys/bus/pci/rescan"Are there any plans to fix this? I am not too familiar with how such things get processed, but it looks like a problem worth fixing?
As mentioned, I am not too experienced with RBP or Linux, but if I can provide any logs or similar to help with the debugging I will happily do so.

3 years ago I found that it was bad hardware that made the USB sub system fail. After replacing the hardware (copy of the prolific chip) I have not seen this again.

I found that it was bad hardware that made the USB sub system fail. After replacing the hardware (copy of the prolific chip) I have not seen this again.
By replacing the hardware, do you mean you replaced your whole RP4 with another, or did you replace (un-soldered & re-soldered) one of the chips on the motherboard, and if so was that chip the VLI VL805-Q6 USB controller? Or do you mean you stopped using one of the USB peripherals you were using, replacing it with another, and after that the problem stopped?
JacoFourie
commented
2 years ago @maratbn
Replaced the hardware that connects to the Pi.
Describe the bug The USB subsystem will stop working at random after hours or days. You can no longer see any connected devices.
Is there a way to get the USB back without having to reboot. Some command I can run to reset all USB.
Only a reboot will fix the issue. Here you can see an lsusb shows no devices and a hub-ctrl says there are no hubs found.
To reproduce Run my libusb program with a python program that communicates with a RS485 modbus
Expected behaviour The programs should keep on working.
Actual behaviour I will start the programs and they may run for days but at some point the USB subsystem will vanish
