Help! USB system stopped working on A13-OlinuXino-WiFi board?

[diracsbracket]

All of a sudden, none of my USB ports work any more
on my A13-OlinuXino-WiFi board? No mouse detected,
no WiFi interface detected. All I can do is using
the UART terminal connection.

I thought I messed up my system somehow, so I even
reformatted my SD card and put a new system on it
(the same u-boot, kernel uImage, script.bin and rootfs
that previously worked correctly), but still the USB
does not work.

This must be a hardware problem then? I even get the error
'unable to enumerate' although nothing is plugged in.
I even have unsoldered the WiFi module from the main board!


Did anyone else had this kind of problem ?

Here is the result of dmesg | grep -i usb

Wow,
The number of replies is overwhelming, really...

Anyway. I measured the 12MHz crystal input signal to the USB host controller
chip and found it is not oscillating, except briefly when I switch on and off
the board. The Xtal seems to be OK and so it the current limiter chip. It
therefore seems the UHC chip itself was damaged somehow

Anyways... instead of sending the board in for repair, I ordered a new one, and
will keep the defective one to practice my soldering/hardware debugging skills
which are non-existent now. Learning the hard way...

I also bought a Cubietruck (Cubieboard 3) and 7" capacitive touch LCD screen.
Hope the capacitive TS is better than the resistive one Olimex uses. Furthermore,
the Cubietruck has a built-in S/PDIF interface, good for my Audio.

Hmm... correction.
The Cubietruck does not provide support for LCD...
It is supposed to be a "mini-computer", dixit Cubie support,
and therefore only supports VGA and HDMI.
