Built-in keyboard hub requires manually making configs for every usb device. Fix?
 
Macally Ikey Slim USB keyboard with two built-in usb ports on Slackware64 14.

Every device I plug into keyboard requires to make a config manually; such as:
Code:

echo 1 > /sys/bus/usb/devices/5-4.2/bConfigurationValue
Dmesg complains there's not enough bus power:
Code:

[  804.571068] usb 5-4.2: new full-speed USB device number 4 using ohci_hcd
[  804.677013] usb 5-4.2: New USB device found, idVendor=24c6, idProduct=5500
[  804.677021] usb 5-4.2: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[  804.677026] usb 5-4.2: Product: HORI PAD EX2 TURBO
[  804.677029] usb 5-4.2: Manufacturer: HORI CO.,LTD
[  804.677033] usb 5-4.2: SerialNumber: 087010DB
[  804.677231] usb 5-4.2: rejected 1 configuration due to insufficient available bus power
[  804.677236] usb 5-4.2: no configuration chosen from 1 choice

This doesn't happen on Windows and everything works fine automatically (including xbox 360 hori pad controller with rumble support and wireless n adapter; both being used simultaneously).

Fix?

What's the output of "lsusb -v" for your keyboard hub? (I'm thinking of increasing the MaxPower ...?)
