Hello,

I found out a problem with the AT91SAM9260EK Development Board and the USB-VBUS DETECT...

perhaps someone coulöd check this...

In the kernel sources 2.6.25 in file board_sam9260ek.c and in the schematics of the demo board Pin PC5 in connected to VBUS.

If I plug in my USB Connector on the left sid are 5V, but on Pin PC5 I measured only 0,8 - 0,9 V ?????

The level should be minimum 2V, so that the software/hardware could detect a high signal on the pin...?

Does anybody else who has this board has the same problems ?

Thank you
