 +====== Internal USB on DNS-323 (B1 hardware) ====== 
 +My DNS-323 with B1 hardware has 88F5182 chip onboard. There are two usb controllers inside the chip, but the DNS-323 itself gives us access to only one controller. 
 +I (bas) discovered the way to get access to the second controller. It can be used, for example, with an usb-stick.

 +The usb_data+ and usb_data- wires must not be too long, or your usb device will work incorrectly.

 +Power source for usb device: 
 +Be careful: in case of accidental short your dns-323 may become damaged.

 +With usb-storage.ko driver the usb-stick works fine. I am trying to install Gentoo on it.
