Board: ADSP-BF548 EZ-KIT LITE REV 1.4

I want to use that board as USB-HOST with uClinux ( with example program on VisualDSP board works fine as USB-Device ).

According documentation, SW16 pin 2 is ON, JP11 both SET.

I have uploaded images from different releases: uImage-bf548-ezkit-2009R1-RC6, uImage-bf548-ezkit-2009R1.1-RC4, uImage-bf548-ezkit-2008R1.5-RC3 , and had the same result: USB does not work: driver initialized, device registered, but absolutely no reaction on plugging any USB device to board (or plugging board to PC).

Boot log looks like:

...

ezkit_init(): registering device resources

SCSI subsystem initialized

usbcore: registered new interface driver usbfs

usbcore: registered new interface driver hub

usbcore: registered new device driver usb

musb_hdrc: version 6.0, musb-dma, host, debug=0

...

bfin-sdh: probe of bfin-sdh.0 failed with error -16

usbcore: registered new interface driver usbhid

usbhid: v2.6:USB HID core driver

...

Then I have compiled my own image (based on 2008R1.5-RC3) in different variations (USB as OTG, as HOST only, as DEVICE only, all with log level=3 ), and had the same result. In /proc i can read status:

root:/> cat /proc/driver/musb_hdrc

Status: HDRC, Mode=Host (Power=20, DevCtl=88)

OTG state: a_idle; inactive

Options: musb-dma, host, debug=3 [eps=8]

Root port status: 00000100

So, is there any other jumper/switch, or option in kernel needed to turn on?

post the full boot log from the 2009R1.1 build instead of snipping out things you think irrelevant

make sure you're using the right cable headers if you're using the combo one from the ezkit package
