+ | ====== 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. |
