Hello!
Sorry for my bad english.
I have a Android Phone. Samsung Galaxy Note. P/n: GT-N7000. I have to
solve the external camerastream play on lcd.
I used samsung opensource update 1. version: 2.6.35.7
I set uvcvideo as modul.
<*> S3C USB OTG Host support
<*> USB Gadget Support --->
USB Peripheral Controller (S3C HS USB OTG Device) ---> .
USB Gadget ( Android gadget)
The kernel works correct. The phone boots up. I can load modul :
insmod uvcvideo.
I have one problem.
The external (UVC) camera is not recognized on my Android phone. I
have asked uvc development. You can see below my emails with uvc
developers. (2 mail)
They have told me:
"-104 is -ECONNRESET. This is a low-level USB issue, possibly related to your
USB controller. I'm afraid I have no experience with the S3C USB OTG
controller. You might have more luck on the linux-usb mailing list (make sure
you mention s3c_otghcd and ECONNRESET in your mail subject)."
I think, that the problem is : my device support only isochronous mode.
I attatch lsusb log from usb uvc extarnal camera.
Please help me, that this problem is:
a: hw problem, my phone will never support this mod .
b: my hw support this mod,only in recent driver ( s3c_hsotg.c) is not
supported.
c: you have patch to this mod :) ( i hope)
d:Maybe, another thing cause "ECCONNRESET Problem".
Please help me asap, because this solution is very important for me. I
have to write one apk. on the phone what use external camera. I can't
start writting of application.
e:Can you see other solution for my problem?
Thank you for your help.
Regards, Szabolcs

This error was get by
drivers/media/video/uvc/uvc_video.c:uvc_set_video_ctrl()
Error -104 mean ECONNRESET
see for error numbers:
include/asm-generic/errno.h
and it was send by usb_unlink_urb()
see for usb error codes:
Documentation/usb/error-codes.txt
Uvcvideo driver never calls usb_unlink_urb(). I assume it was made by
usb host controller driver. Some where here drivers/usb/*
You will need to find why it was called. May be it is some software or
hardware bug.

-104 is -ECONNRESET. This is a low-level USB issue, possibly related to your
USB controller. I'm afraid I have no experience with the S3C USB OTG
controller. You might have more luck on the linux-usb mailing list (make sure
you mention s3c_otghcd and ECONNRESET in your mail subject).
