Problem with usb stick

[Boken Lin]

@Milan-Vuckovic Are you connected to the Omega via serial terminal or via SSH? Can you connect via serial terminal, and tell me the message that pops up in the terminal when you plug in the USB key?

[Milan Vuckovic]

Ok. I will try now.

[Milan Vuckovic]

I'm getting no response when I try to run command screen /dev/tty.SLAB_USBtoUART 115200.

[Boken Lin]

@Milan-Vuckovic Did you press ENTER to activate the command console?

[Milan Vuckovic]

Yes. It says: "Cannot open line '/dev/tty.SLAB_USBtoUART' for R/W: Resource busy"

[Milan Vuckovic]

I restarted my laptop and omega, and tried command again. And I got this screen:

[Boken Lin]

@Milan-Vuckovic When you press ENTER nothing happens?

[Milan Vuckovic]

Exactly.

@Milan-Vuckovic Can you take a picture of your entire setup? How you connect the Omega to the dock, and how you connect the dock to the computer. And can you also make sure that the Omega is plugged all the way into the dock? Sometimes when the connection is loose, there might be some issue as well.

@Milan-Vuckovic Seems like the Omega isn't plugged all the way into the dock. Can you plug it all the way in and see if that helps?

[Milan Vuckovic]

I can see it now. Thank you for your help.

[Boken Lin]

@Milan-Vuckovic Awesome. Now try to plugin the USB stick and tell me the output that you see on the screen.

[Milan Vuckovic]

I can see the disk now, and I have successfully performed mount. And the serial console is now working too.

[Boken Lin]

@Milan-Vuckovic Awesome A picture is truly worth a thousand words!

[Milan Vuckovic]

Again, thank you for your help and I'm sorry for inconvenience. I was not really sure that omega should go all the way into the dock.

[Boken Lin]

@Milan-Vuckovic That's what we're here for!

I have a problem with all USB devices. I've never been able to get any USB device to work. I figured it was a software/kernel issue and tried to work it out myself since I got the Omega about 2 weeks ago.

Now that there's been a firmware update, I decided to give it another go. USB devices just don't connect. I tried to look up what the errors meant and read something about needing a Powered Hub. I hooked up one of those and there is no difference in the behavior.

Below is the output of dmesg, when inserting 3 different USB storage devices. (USB v2 2gb, USB v3 16gb, and v2 card reader with a 4gb sdcard. All of these cards work fine in other PCs and on other development boards I own.

Any ideas? I just tripple checked, the Omega is fully seated in the dock.

Hi @Mike, I was doing some google search on this. Can you try to see if the following works:

cd /sys/bus/pci/drivers/ath9k
echo -n "0000:00:1d.7" > unbind
