Best information to output would be the debug in qh_init in drivers/usb/host/dwc_otg/dwc_otg_hcd_queue
This function is called to create a new queue head when we add a new endpoint to the system. This is done each time you set the interface (I think it'll be done each time you open the device but it will be device dependent)
The interesting thing would be the settings of all the qh's in both the working and non-working case to see if there is a clear difference, I'm currently working on the hypothesis that the problem occurs when we create a new endpoint and the interrupt endpoints are scheduled badly such that the keyboard interrupt occurs just after the ethernet interrupt schedule, therefore when the keyboard interrupt occurs the processor is likely to be busy processing the network stack so the latency kills us with the split transactions!
So I'm most interested in
qh->sched_frame
qh->interval
for each of the endpoints (so you'll also need information such as the device number and endpoint number!)
As to why you are seeing such an effect when not powering down correctly I can only assume this is because when you power back up it is doing more disk checking type work when it recovers...

Re: USB redux
To recap what I am observing (in layperson's terms): pushing large chunks of data via USB makes causes problems. In my environment this means webcams and digital picture frames. My DPF runs fine unless I load a bigger image (e.g. as background or the lcd4linux splash screen). My webcam is unusable since the resolutions it would support lead to timeouts on the bus (my interpretation of the debug output, a lower resolution webcam runs fine). A USB sound card runs fine, I assume the data rate is low enough.
Is there any progress being made? I am not using the LAN port, would USB performance be improved if LAN gets switched off?

Re: USB redux
Here are two snips of /var/log/message for the good and bad kbd separated by boot cycles. And yes, the primary difference is a file system check with fsck. Will need a little/lot help if specialty debug/log captures are needed.

Re: USB redux
just a note on the gphoto2 crap out - I use it with the pi directly connected to the camera via usb and with a nano wlan adaptor in the other usb in other words NO hub
Re: USB redux
In my case it's the other way around... I have a brand new 4 port powered Hub that whenever I use it the Wifi adaptor drops out constantly. Then I have a like 5 yr old 7 port DLink hub and it works rock solid. If I take away the hub and just use the Wifi adaptor plugged directly into the RPi (512MB model) it is flaky. I'm using an Apple iPhone power adapter to drive the RPi.MaxK1 wrote:Or 7 funky ones...
I think a lot of it is how good the power supply on the hub is as well... (Note, in neither case am I trying to run the RPi off the hub.)
Re: USB redux
Coming back into this - I have finally changed the wireless adapter to an Edimax one instead of the Ralink one and the Pi is subjectively more responsive and hasn't fallen over yet! We shall see how it proceeds.
Re: USB redux
Right. I've started getting USB crashes again.
I'm powering my pi directly from the GPIO headers using a UBEC which provides stable 4.95V @ TP1-TP2.
When the crash happens this is what syslog says:
The 1min.py scripts is simply a script which reads 1 DS18B20 sensor over the GPIO pins and saves it to a .log file on the SD memory card.
Does anyone know of a way to reset and force the USB interface and network interface to restart without rebooting the pi?

Re: USB redux
Sorry for spamming this thread so much, but I created a short script which reboots the Pi if the network and a chosen USB peripheral isn't found. A dirty fix but should keep a remote pi accessible.
Put it to your sudo crontab -e and run it as often as you like.

#This script checks if the USB interface has crashed. If it has it then reboots the Raspberry pi and tries to fix it.

#Call the Ping command and ping the IP once and log the return to the ret variable
ret = call(["ping", "-c 1", IP_FOR_TEST])
#If the return is not successful...
if not ret == 0:
#...log the date and time..
with open("/home/maxion/logs/usberror.log", "a") as logfile:
logfile.write("\n" + str(datetime.datetime.now()) + " " + IP_FOR_TEST + " is unreachable")
# and then check if the USB device 006 on bus 001 is reachable and log the return to the variable ret2. 001:006 is my webcam which is always connected.
ret2 = call(["lsusb", "-s 001:006"])

Re: USB redux
Yeah that should contain the same bug fix.. you could try tickling the interrupt mask to see if that makes it wake up again
Just try the following to see if it's locked up waiting for an interrupt...

Re: USB redux
Excuse me.
Do you know why there is no new commits at https://github.com/raspberrypi/firmware/ for a month?
Is there any change of way how new firmware is distributed?
Or maybe there were some problems with latest work?
Thanks:)

Re: USB redux
I have two Logitech webcams that both use the uvcvideo driver.
Bus 001 Device 005: ID 046d:08c3 Logitech, Inc. Camera (Notebooks Pro)
Bus 001 Device 005: ID 046d:09a6 Logitech, Inc. QuickCam Vision Pro
I have tested both with mjpeg-streamer, but only the Notebooks Pro webcam is usable.
Both webcams drop frames with the error message "USB isochronous frame lost (-63)", but the Vision Pro drops most of the frames and is unusable in practice. Here are the details for these two webcams that hopefully could shed some light on why one works much better than the other.
First is the information for the Notebooks Pro and the next post contains the information for the Vision Pro.

Re: USB redux
It seems to me that the latest kernel and firmware have solved (some of) the problem.
I have a python app that collects serial data every 250ms through a FTDI usb-serial converter from a charger. With the official Raspbian image 2012-12-16 the system was freezing after a few hours.
I did rpi-update and I'm now on
Linux raspberrypi 3.6.11+ #346 PREEMPT Fri Dec 28 00:50:33 GMT 2012 armv6l
Dec 28 2012 11:20:48
Copyright (c) 2012 Broadcom
version 359904 (release)
and could collect data for 18 hours without a freeze. That was not possible before.

was this at USB 2.0 speeds ? or USB 1.1 (dwc_otg.speed=1)

Re: USB redux
There were, but it was on the "next" branch, as the switch to newer kernel (3.6.11) and GPU firmware required more careful testing than the usual smaller changes.kermitas wrote: Do you know why there is no new commits at https://github.com/raspberrypi/firmware/ for a month?
The testing was positive (after a few bug fixes) and got merged into master tree a few days ago, so an rpi-update will now get you the newest firmware.

Just checking in again, on USB topics. I have updated to the latest firmware and OS.
pi@raspberrypi ~ $ uname -a
Linux raspberrypi 3.6.11+ #348 PREEMPT Tue Jan 1 16:33:22 GMT 2013 armv6l GNU/Linux
The config.txt and cmdline.txt, I believe, are again stock.
dwc_otg.lpm_enable=0 console=ttyAMA0,115200 kgdboc=ttyAMA0,115200 console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 smsc95xx.turbo_mode=N elevator=deadline rootwait
The symptoms I have consistently observed are that the USB kbd and mouse will skip/repeat if the prior shutdown was improper. A second (or third) powercycle of pulling the plug will restore proper fuctionality. However, no instance of improper behaviour is observed IF a proper shutdown is done on the prior cycle.
# shutdown -h now
I have uptimes measured in days and cannot find fault, when properly shutdown.
my 2 cents.
Lou

Re: USB redux
Can you try this:
1) Pull the plug without shutting down
2) start up and observe the bad keyboard behaviour
3) Unplug keyboard and plug it in again and see if the problem goes away (repeat it a few times...)
Thanks
Gordon
