# embedded linux and powering usb stick

I have a trouble where I require to read a usb - stick or a usb keyboard: When I connect in the USB stick or keyboard I can not get power to the tool. dmesg claims absolutely nothing

I tried:

for device in $(ls /sys/bus/usb/devices/*/product); do echo$device
cat \$device;
done


for obtaining details in console and also I get this output:

/sys/bus/usb/devices/usb1/product
Freescale On-Chip EHCI Host Controller


I can not see any kind of kingston usb stick or keyboard.

Quesitons:

1. How can I power my usb tool mdev or /sys/bus/usb/devices/*/power
2. How to read information from keyboard or usb stick
