I am trying to load a firmware up-rev to a device with a USB stick. It doesn't see the stick. My USB D+ and D- signals have what looks like a clock signal embedded onto them. The chip is an ISP1362 USB OTG controller see www.farnell.com/datasheets/1668574.pdf
I have not found any components that seem to be bad.
To see a picture of the D+ incoming signal that looks like it has the clock signal mixed into it, copy and paste the following into a separate window.
The scope is set at .5 usec/div.
20 3v 21 3v 22 3v 28 3v 29 3v 23 0v 59 0v 60 3v 48 0v 45 3v 30 3v 41 5v
46 signal shown when USB first inserted, otherwise 0v
47 inverted signal shown when USB first inserted, otherwise 3v
33 0v 34 0v 61 3v 62 3v 56 5v
4, 14, 26, 40, 52, 56 3v
1, 9, 19, 27, 57, 51 0v
Any guess as to what the problem might be?
