[9fans] r-pi usbotg error

[9fans] r-pi usbotg error

[Ramakrishnan Muthukrishnan]

Hi,

I just wanted to report an error I just saw on my r-pi which had been
running for the last ~3 hours or so. While I was away from the
keyboard, the screen was up and after a while I saw it going blank.
The keyboard is no longer active though I still have a working mouse.
On the console output, I see these prints:

usbotg: ep6.1 error intr 00000082
kb: /dev/usb/ep6.1: read: i/o error
kb: exiting

that very occasionally happens to me.  try replugging the keyboard.

Sounds like the keyboard went idle (on its own!?) and the Rasp lost
connection to it. ep6.1 is the name of a USB device (something about
logical unit devices or something,) you can try unplugging something and
you'll see similar things pop up. kb is complaining the keyboard went away,
and since there is no keyboard, died. You could try ungplugging it and
plugging it in.

00000082 -> transaction error.  "transaction error" is too vague to
pinpoint a culprit.

I'd bet almost always on the keyboard/periferal device, though.

Yes, indeed, it came back to life after unplugging and re-plugging. Thanks.

Of course, I will be happy to collect any more data to help debug this.

unfortuantely, i don't know what to ask for.

i am not convinced that this is a device problem.  and i can't
just now think of a test that could prove the issue one way or
the other.

due to the cronic lack of documentation, and the error's lack of
specificityi think the right way to debug these sorts of issues is to
get a usb analyzer.  i don't think i have the free $$ to do this on
for fun right now, unfortunately.

looks like i could use a keyboard<->chair protocol analyzer, too.  who
knows what's wrong with that connection.

Last night I finally got around to getting a B+ I've had sitting in the
closet and converted it to a terminal. I'm seeing this same problem. I've
tried unplugging multiple keyboards and have also tried using a powered
hub. I'm at a loss. Has anyone else figured out how to deal with this issue?

I'm not experiencing this issue (I've got a cheapo, 5+ year old USB
keyboard, of make and model that I don't recall, attached to a B+ that's
been running for a few days without an issue, plugged directly into the B+)
Could it be associated with particular keyboard models?

I use a standard dell keyboard with my b, not b+, and never had a problem.

I've had mixed results between keyboards. From what I have experienced 
the keyboards that have usb hubs built into them drop, but the keyboards 
without hubs (or with the hub wire unplugged) didn't drop connection. ymmv

Interesting. Both keyboards I tried had hubs built in. I have a generic
Lenovo on the way (should be here tomorrow). I'll give that a shot.

I am on my Pi terminal now.

I have a Dell KB1421 keyboard and an

I have a similar problem. I have a usb kvm and I share the keyboard and
mouse between a PC and the r-pi. When I switch from the PC to
the r-pi there is usbotg error, but if I swtich again to the PC
and again to the r-pi then it works (it means I have to switch
twice each time I want to use the r-pi).

Just curious. Does this depend on which of the 4 ports is used
or happens with any of them?

I've tried every port to no avail.

i've had good luck, once i fixed some userland usb niggles.  i've put a
kernel up on /n/atom/ftp/^(s9pi 9pi)^.bz2 if you'd like to try it.

it would be fun to roll up a usb debugging image a bit later this week,
if it's still an issue.

Just for the record, I use a classic IBM clicky Model M with a ps2/usb
adapter, and a very cheap generic chinese usb keyboard, both problem
free without any external hub.

Patch /n/sources/patch/maybe/usb-short-desc makes a lot more keyboards
work (especially some with hubs).

While working on the pi2, I have discovered one glitch which also seems
to be the case on the B+ but not the B or A: after rebooting with the
"reboot" command (as opposed to resetting the power or using ^t^tr)
the keyboard won't respond without being unplugged and replugged.
Perhaps the built-in 4-port hub on these pi models needs some sort
of reset which the 2-port hub doesn't.

Unfortunately I didn't see any change with usb-short-desc applied, though switching to the Lenovo did the trick. I'm very happy with how the new terminal is shaping up so far.

Thanks!

one and figure out what's going on.

I had attempted to use a Sun Type 7 and an Apple wired (full size)

the apple wired keyboard comes in several flavors.  do you mean the slim on
or the thick one?  i think there's a code on the back.

the thick one has trouble.  i should go back and look at that.  i think i posted
some of my issues to 9fans last year.

This was the newer (thin) model. I picked up about a year ago.

I just used a powered hub and it worked fine.
