Hi Jordan,

The hardware problems is not my interest since the beginning.
I got OLPC mainboard on June 26, 2006 and simply plug-in my NGUD-11.4 and 
it work w/o problem but need usb LAN.

I did not know someone already made usb8xxx to work correctly already.
So, the first job I did is trying to make it work firstly on my own by 
using ndiswrapper under NGUD-11.4 and hopeless because no appropiate .sys 
exist. I try mrv8k and did not work on the same reason. Until someone told 
me I need the right firmware under usb8388.ko So, I did compiled it and it 
work ok on my own using kernel from kernel.org because I do not know it 
has favor to use only fedora in here.

For sound problems, because you say s/o already make it work so, I will 
not touch this part any more.

I did probe all existing sound.ko and it look like below:

Ofcause, I did use .img from your site on your request.
But it cannot produced sound even I forced to mknod on sound dev as 
below:

crw-r--r--    1 root     sys       14,   3 ¡.¤. 6  2006 dsp
crw-r--r--    1 root     sys       14,   0 ¡.¤. 6  2006 mixer
crw-r--r--    1 root     sys       14,   1 ¡.¤. 6  2006 sequencer
crw-r-----    1 root     sys       14,   8 ¡.¤. 6  2006 sequencer2

After reboot, all sound devices on /dev always gone.

For me, to make usb8388.ko to work correctly is sufficient for me to 
continue my work in making your developed softwares to work correctly in 
Thailand.

And I did start to make Thai features like date and time in Thai to work 
as above list :)

I will put the .img for download after I work out sufficient progress.

supat
