I was having some trouble with a pegasus usb ethernet an OpenZaurus, kernel 2.6 spitz.
The kernel module doesn't catch the pegasus because in kernel 2.6, the kernel now keeps track of USB power budgets, because of that some usb devices doesn't get configured by the kernel, the solution...
use lsusb -v , to see the power requeriments, if you think that are aceptable, at your own risk..., use
echo -n "bconfigvalue" >/sys/bus/usb/devices/"usb address"/bConfigurationValue
example:
echo -n 1 >/sys/bus/usb/devices/1-2/bConfigurationValue
where 1 is the config value you see in lsusb -v, and 1-2 is the address of the usb device...
Sorry for the bad english, because i don't speak it very well...

great information, thanks for posting it, this is valuable information to me.
as for your English, it's better than any foreign language I speak!!!
WOW! Thanks 
I got my portable Iogear mini USB SD card reader to connect with the above solution. The light finally lights!!
It's only 250 mA
It self mounted as /media/sda1
I just used the exact same commands, as I couldn't figure out what the address is for my USB reader.
echo -n 1 >/sys/bus/usb/devices/1-2/bConfigurationValue
I found the config value, but which number (in the below output) is the address?
This doesn't seem to be a permanent solution, because the light doesn't come on or connect when unplugging/replugging the reader.
Is there a way to "keep" this setting and make it permanent, so every time I plug in my mini USB SD reader, it just mounts like in pdaxrom/cacko?
