video errors while running USB webcam on ARM linux system

video errors while running USB webcam on ARM linux system

[ravi]

Hi,

This is my first post in this forum.


I am using a USB webcam from Dream Logic-AP1501,a taiwanese company.I have downloaded the provided by you i.e gspca-20071224 tar file.I am trying this USB webcam 

to work on ARM9 processor,after cross compiling  and porting the module, i am able to detect my USB webcam  as "SONIX JPEG camera".


As an application,i have downloaded spcaview-2006108 and i am able develop spcacat,spcasev executables.These are the applications which are supported by thr driver which i have downloaded.


Second problem: [On ARM based system]


while running this command:


spcaserv -d /dev/video0 320*240 -w 30 -f yuv


i am getting error: "Error in opening V4L interface".I checked with dmesg command:

I am getting this messages:


"/source/gspcav1-20071224/gspca_core.c:init isoc:usb_submit_urb(0) ret -38"

split I/O support disabled"


After googling and reading some discussions, i have came to know that:


error -38  is ENOSYS comming from the usb layer, and the the Webcam driver writer has suggested to change the USB socket.
I need your support for these problems.


Thanks & Regards,

The driver gspca v1 is not maintained anymore. You shall use the gspca
v2 instead (look at my page).

Otherwise, the error -38 seems to indicate you have problems in the USB
subsystem (usb driver? - check the loaded modules - ohci/uhci/ehci).

Best regards.
