Argh... your message is very difficult to read, as there is no
difference between your text and mine. Please see

I don't dare to say "always" ;-)

But if you tested so many devices, and none of them is working,  then
this is probably an indication of another problem.

Do you have  a  chance  to  try  a  different  board?  Did  you  ever
succesfully  use  *any*  USB  device  on your board? Maybe there is a
hardware problem on your system.

Ummm... stupid question: is the green LED behind the USB connector on
your board on or off?

Best regards,

Wolfgang Denk

The Icecube board has the USBP11A transceiver and our custom board has 	the
ISP1105 (this has a problem with low speed devices according to PHILIPS).

We get the same message when we connect the hub itself to the USB port
Does anything need to be configured in the kernel to accept the USB hub, if
so which switch is it?

I'll relay this to our hardware guys.

We had that problem on a few of our boards as well.

For the old Icecube exists the possibility to mount two different USB
transceivers, one of them the ISP1107DH, the other one the
P11PAPW. Which one of the two is mounted on your board?

On our own boards we had problems with low speed devices and the
ISP1107, the other transceiver that Freescale used worked
fine. Connecting those low speed devices via a hub worked. Sometimes
it helped to add an additional capacitor to the power lines, but
that's not really a viable solution.

We ended up using a Fairchild USB1T11A, the ISP1107 seemed to have a
problem, we just didn't have luck with them. The Fairchild's are pin
compatible, maybe you just give it a try.

Mr, Denk

It might be, but I can not figure out what it is. I am hoping it is just a
kernel configuration mater.

I just have one icecube board (Lite5200 Ver 2.0), and I have 4 of our own
custom boards designed after the icecube. Right now I am testing on the
icecube board. I tried our boards but usb as mass storage is not working
there either.  

>Ummm... stupid question: is the green LED behind the USB connector on
>your board on or off?

There is one and it was off, I shorted out R164 and the led came on. Our
custom board takes care of this as well 


Which defconfig file should I use? 
I just tried the icecube_5200_CoralP_defconfig file but now the board is not
booting; it hangs right after this message:

"Uncompressing Kernel Image ... OK"


Thanks, 

Orges

I assumed that outlook would do it automatically, but apparently it did not,
sorry about that.

I hit "reply" instead of "reply all" by mistake; sorry about that too, I
will not happen again.

Are you just trying one specific type opf USB device,  or  does  this
happen with several 5 or more) different devices?

We tried 6 different USB flash drives:
	GE intelligent stick 2.0 (256MB)
	PNY
	SanDisk Cruzer Micro (256MB)
	Version G (512MB)
	Memorex traveldrive mini (512MB)
	Unknown brand (64MB) 

Are there any flashdrives that are known to always work?

You can just use the  default  configuration  as  provided  with  the
kernel  tree.  Make  sure to use a current kernel (top of tree in git
repo).

We have the latest 2.4 drop from the git repo. Which of the defconfig files
should we use? None of them had usb storage enabled (icecube board).
 

Thanks a lot,

Orges

And keep in mind  that  many  USB  devices  are  simply  not  strctly
standard conforming. Some will work, others won't.

Wolfgang Denk
