USB Issue Troubleshooting

[lanscene]

I think Adapteva folks use the same power supply/USB hub/cable to test the board,
So they can't reproduce the fault.
do they suppose all the people around the world should buy the same band peripheral？
BTW, I use SKU101020.

I am attempting to use the usb port for a real usb instrument device. I connect to this device using other boards, but can't with the parallella.
Whenever I try lsusb I get the message "unable t initialize libusb -99"

* Failure mode (sometimes or always?)
ALWAYS

* Headless/hdmi configuration
Headless

* FPGA/Linux/Ubuntu version being used
ubuntu-14.04-headless-z7010-20150130.1

* Fan used?
5V 0.09A 60 mm Fan

* SKU#
I can't see it, covered by case. Will remove it if I have to.
It is not from the kickstarter, and it is a desktop version

* Power supply used
5V 2.5A CUI

Has the issue with the USB been resolved? I have a new Parallella-18 7010 board running the latest Ubuntu distribution. My USB intermittently worked with the first few tries, but now consistently fails to recognize the USB devices. I tried a couple of the USB workarounds, such as a powered hub, to no avail. The board responds fine in headless mode, so most of the functionality is there, but not the USB.

What is recommended as a fix, or does this mean I have a broken board? FYI, the heatsink has been installed, and I am using a fan.

It's not a broken board, or rather, it's not a problem that will be fixed by you getting a new board.

My USB only works with a powered USB hub. I've never managed to get passive USB working and I've tried several kinds of cables and passive hubs.

Cannot get USB working on Parallella kickstarter board regardless of how the devices are connected. Direct, powered hub, different powered hub, unpowered hub, doesn't matter.

Thanks for the reply. I have been using a powered hub, a Sabrent model, to no avail. What type of powered hub are you using? Perhaps there is some issue with either power back-feeding or timing with specific cables that makes the initialization flaky.

Hello,

* Failure mode (sometimes or always?)
I have not been successful in getting USB working.

* Headless/hdmi configuration
I first tried Headless then switched to the HDMI version which I've been using for most of my tests.

* FPGA/Linux/Ubuntu version being used
Linux Parabuntu [Last Linux ]

* Fan used?
No.

* SKU#
P1601-01, SN 0017115 (The large heatsink didn't make this easy).

* Power supply used
USB cable coming from a powerboard with USB power plugs. No indication of power problems.

I have tried
- Power cycling the board with and without each of the peripherals attached. Use Power Supply 5v 2.4A


The board boots every time.
I have not any success with USB.

USB notes:
I am using a USB adaptor. I've tried a number of peripherals:
- HUB USB Hamlet, Mcally, Tucano and other. Passive and not.
- Long Cable for USB Kb and Mouse.
- SanDisk USB drive
- USB sound card.

Cheers
