Missing incomming USB HID packet on RP4

yoctopuce commented 5 years ago

Describe the bug

Incomming USB HID packet that work at Full Speed are not reported by the libUSB 1.0. Using an USB analyser we can see that all packet are acknowleged by the USB Host controller, but in the application the configured callback never get called. We have not been able to determine if the issue is in the libUSB or the Linux kernel. But we have write a simple program exhibits the problem. It's a simple threaded example that iterates over all Yoctopuce connected devices and send 15 USB packets. For each sent packet the device with respond with an USB Packet.

To reproduce We have publish on GitHub a complete description of the problem and a program that exhibits this issue: https://github.com/yoctopuce-examples/raspberry_4_usb_bug

Expected behaviour Incomming USB HID packet should be reported by the LibUSB 1.0.

Actual behaviour Incomming USB HID packet are not reported by the LibUSB 1.0.

Please capture an event trace that includes plugging the device in and running the command until it fails. Once the command fails, immediately unplug the device.

sudo -s
cd /sys/kernel/debug/tracing
echo 1 > events/xhci-hcd/enable
[Plug device in]
[Perform device manipulation until it breaks]
[Disconnect device]
cat trace > /home/pi/some-sensible-filename.txt

The trace is going to be large, so it may be better to add as an attachment rather than inline. Ideally, capture a trace where the device breaks on the first invocation of your test program.

To clear a previous trace (events will still be enabled):

# echo > trace

yoctopuce commented 5 years ago

I've first updated the firmware to see if I get any "magical bug fix" but the bug is still present.

Then I've run your test and updated the bug report repository with the requested traces:

https://github.com/yoctopuce-examples/raspberry_4_usb_bug/tree/master/xhci-hcd_traces

Let us know if you need any other informations?

Note: If you want to reproduce the bug in your lab, we can send you a device free of charge. Just send use an email to support@yoctopuce.com.

P33M commented 5 years ago

I am unable to reproduce the bug on either a Yocto-Light-V3 or a Yocto-RelayHi1

Both devices have been updated to latest Yocto firmwares. The Pi 4 has no other devices attached and is using VLI firmware version 0137ab.

An upgrade of the VLI firmware can be done semi-automatically by installing the apt package rpi-eeprom and rebooting. To check the current version of bootloader and VLI firmware, run sudo rpi-eeprom-update with no arguments.

yoctopuce commented 5 years ago

You are right with the latest firmware the bug is fixed.

Now the big questions are.

When this new firmware will be installed by default?
How can I detect which firmware is installed without rpi-eeprom package?
And do you have any official documentation on the magic command sudo rpi-eeprom-update -a?
What is the difference between rpi-eeprom-update and sudo rpi-update ? Will one day rpi-update install this new firmware?

The problem is that we have multiples customers who are using our product on Raspberry Pi 4 and our product is not working correctly on it. It would be nice to have some documentation which explain what the sudo rpi-eeprom-update -a do and what will be changed. Do you have some documentation and/or release notes where we can forward them to?

When this new firmware will be installed by default?

It is installed by default if the rpi-eeprom package is installed. The package is not yet a default package but this will change soon.

How can I detect which firmware is installed without rpi-eeprom package?

The package installs a tool that reads the pci config space for the firmware version. Alternatively, use the pciutils tool lspci to read the config space:

The firmware version is at offset 0x50 and is 4 bytes long: ab 37 01 00 => 000137ab

And do you have any official documentation on the magic command sudo rpi-eeprom-update -a

The program is a shell script. Documentation on the bootloader and bootloader utility is here: https://www.raspberrypi.org/documentation/hardware/raspberrypi/booteeprom.md

What is the difference between rpi-eeprom-update and sudo rpi-update ? Will one day rpi-update install this new firmware?

rpi-update will never touch bootloader firmware. rpi-update only updates files on the boot partition of the SD card and any associated kernel files.

JamesH65 commented 5 years ago

rpi-update should not be used for general updates. It pulls in untested beta software, so should not be recommended to end users. Use apt for all updating.

yoctopuce commented 5 years ago

I've done more intensive test and I confirm that the following commands fix the issue:

sudo apt-get install rpi-eeprom
sudo rpi-eeprom-update -a

Thank's for your help

sbazaz commented 4 years ago

Hi yoctopuce,

We are experiencing the same issue with one of our HID devices and RPI4, to be clear the HID device is not one of your products. The RPI4 firmware update improves the number of packet losses on RPI4 but does not eliminate it for us. I look at the USB bus traces you posted and noticed that you send one request per second and I was wondering if you ever performed the test at much higher rate (maybe send the requests in a tight loop) to see if any packet loss occurs?

Thanks

yoctopuce commented 4 years ago

Our production code send much more packet (up to 1 every millisecond) and everything work fine.

JacoFourie commented 4 years ago

Hi. We are starting to use LibUSB on the Pi. On the Pi 4 all works fine. But on the Pi 3 I get random corrupt data and timeouts. Is there somthing I need to do on the Pi 3 to get it to work the same way as the Pi 4 ?

yoctopuce commented 4 years ago

No. our code work on all Raspberry Pi.

JacoFourie commented 4 years ago

Hi. do you use LibUSB 1.0.0 ? or do you use Libhidapi-libusb or libhidapi-hidraw ?

yoctopuce commented 4 years ago

LibUSB 1.0.0.

You can have a look at the source code of our C++ library: https://github.com/yoctopuce/yoctolib_cpp/blob/master/Sources/yapi/ypkt_lin.c

JacoFourie commented 4 years ago

I am getting random timeouts and corrupted data on the Pi 3 when I use linUSB. If I use linhidapi_libusb I aslo get the same errors but if I use libhidapi_hidraw then all works fine. I am communicating with a very slow usb device. Where can I start to look why the code does not work on the Pi3 but well on the Pi 4 ?

yoctopuce commented 4 years ago

Hi, it seems that the bug is not completely fixed.

I've updated the distributions and the EEPROM but without any success

When I run the same test but for longer and with more devices (>4 devices) I've randomly have the same issue: I no not receive one USB packet. The problem seem to be some kind of racing condition and is very hard to isolate.

What I've been able to see it that every time the USB capture (done with usbmon) end with a URB status of -108:

I've updated the debug program to run the same test for longer and multiples time: https://github.com/yoctopuce-examples/raspberry_4_usb_bug

Could you see if you are able to reproduce this issue?

sbazaz commented 4 years ago

Our USB HID products show the same problem on RPI4. They work without any issues on other versions of RPI.

It seems when bInterval value of the out endpoint is set to 1, the host side driver occasionally does not pass the reply from the device on to libusb even though it was present on the bus.

Changing the out endpoint descriptor bInterval value from 1 to 2 in our device's firmware makes the problem stop occurring. For now we had to use this change as a workaround until the issue is fixed in RPI4.

IvoBCD commented 3 years ago

We're also noticing this, with RPI4 SiLabs CP2112 (both with kernel driver, and user-space driver). And yes, this device also has an out endpoint with bInterval set to 1. Unfortunately we can't change bInterval.

d-csr commented 3 years ago

I have a similar problem with a 3rd party device, bInterval=0, using interrupts. It randomly just misses packets and needs to be reset to work again.

srinsoz commented 3 years ago

Changing the bInterval cannot be done for our devices, doing that will have performance drawback on all other platform (including Raspberry Pi 3). Does anyone is still investigating this issue?

sirus20x6 commented 3 years ago

We believe we are having this issue with our custom usb full speed hardware, but changing the binterval does not seem to help us.

jmw182 commented 2 years ago

I am also experiencing this issue with an 8 GB Raspberry Pi 4 with the latest VL805 firmware (000138a1). I have tried both the latest 64-bit Raspberry Pi OS (Bullseye) and Ubuntu 22.04 (Jammy). My device uses bInterval 1 and the raspberry pi frequently fails to read from the device (HID interrupt reads). I do not have this issue when using a raspberry pi 3B+.

Are there any updates on this issue?

buha commented 1 year ago

I'm experiencing this issue on Raspberry Pi 4 by using openocd to program some Maxim microcontrollers. Openocd uses hidapi which seems to not work well either due to RPi4 HW or FW issues.

With the original RPi4 firmware, the failure in programming microcontrollers with openocd occurred >90% or the time. With the latest RPi4 firmware the situation improved to maybe half/half but wasn't fixed.

jeanphi-francois commented 1 year ago

I have a similar issue. I have a software working fine with a CM3+ board. Software communicates with and HID device, and never misses anything on the CM3+ version. It occasionally happens on the CM4S board. I can provide pcap file if it helps. Kernel is built from linux-1.20230405 tag
