Hi as follow up to this post it seems a hardware issue.
Maybe someone can tell me which parts to check...
Output from dmesg (Ubuntu 14.04.5 x64)

Flashing with OpenOCD and Buspirate over JTAG works fine.
But USB connection to the AT91SAM7S256 is broken.
Thanks

Is this a usb3.0 port?

No.

So, you tried different usbports, tried different usbcables, made sure the usbcontact is not loose on the pm3 pcb board?.
Offline
Yes all check. Still doesn't work. I guess I will try connecting the AT91 directly and see what happens.
Offline
If you bought the pm3 recently? You may consider RMA it..
Or try it on a different computer...

I recently figured out the reason:
As you can see here on the pinout and in the documentation of the AT91SAM7S256:
XT2 is responsible for the USB to work. I had trouble with the crystals. New crystals are arriving today. It should fix the issue.

You seem to be well versed on hardware. Good that you figured the reason out, maybe you can explain how to program the FPGA

Thank you, just digging into the pm3. I built it myself, ordered the parts 2 months ago. So if there is anything I can answer I am glad to help

It just me who has a hard time understanding the electronic part becoming a digital signal. The whole verilog part where things happens all at the same time which doesn't make sense to me.

Yes for me it's too much at the moment too. I was just sad spending so much money on the parts and time for soldering and I did not know what the root cause was for the bad usb when the pm3 itsself seemed working. So after UPS arrives I can solder the crystals.

great project, but myself I wouldn't have managed to make one. Soldering and all. I buy it instead.

Hi, I have to revival this thread. Could you tell me on the board where is the crystal XT2? And is there anyway to check that the crystal is working or not. I have similar fault on my PM3 bought 2 yrs ago "USB device not recognised"
edit:
Tourned out that my board has not got the same HW fault with the crystal XT2.
The history was: Proxmark will no longer boot; connect to PC I got fault report "USB device not recognised"; 4 LED lights constantly lit.
Using the Segger Jlink and following the setup in the thread
"Play with JTAG" by Asper
AND the recovery procedure on GIT
https://github.com/Proxmark/proxmark3/wiki/Compiling#jtag-recovery-procedure,
I have been able to recover my proxmark
