Sony Motion Eye Web Cam - firmware loading

Well, after searching several forums and trial and error, I finally got my builtin webcam to work. Its r5u870 05ca:1836.

The only problem I now have is that after a hard boot (system was powered down), I then have to do a soft boot for this to work properly.

It seems to me that the problem is the firmware loading. Obviously, doing a shutdown -r means that the firmware remains in the webcam device and then everything seems OK.

After a soft boot:

linus:~/bin # lsmod|grep -e sony -e uvc -e r5u
r5u870 26436 0
usbcam 47808 1 r5u870
sony_laptop 35688 0
uvcvideo 66124 0

NOTE: After a hard boot, luvcview will not display anything after the line beginning with

Any ideas on how to make this all work without the soft reboot?

Thanks in advance.

How did you get this to work in the first place ? What rpm (if any) did you install ?

I’m wondering if after a hard reboot the kernel module is just not loading, and you only have to do the appropriate “modprobe -r r5u870” command or something like that ? ie:

modprobe -r uvcvideo
modprobe r5u870

but this is really just me speculating rather wildly.

Why am I really posting then? Well … any chance that you can help out on this thread: sony laptop inbuilt webcam
