(I did not do the black robe and candles thingy, though.) I also did what was recommended in another post (somewhere on the internet): unplug all USB devices, shut down, unplug the power for 40 seconds. I did enable those kernel options, built usbcore as module just in case I need to pass arguments, booted with nothing but camera plugged in. You should plug your webcam alone on a hubĮheh of course if your webcam is powered by itself then my theory fall into flames. It show you have plug your keyboard and webcam using the same root hub, and usb root hub have a limit for power, and the maximum limit is shared by all devices plug in the same root hub.Īnd you can easy guess the webcam need 100% power to function.

Please learn how to denote units correctly! This camera works well in another computer. I tried use_both_schemes=y and I tried to force old_scheme, no joy. Sep 24 20:06:36 sipp kernel: hub 3-0:1.0: unable to enumerate USB device on port 1

Below is lsusb output, webcam is plugged in. Manufacturer claims it has 6 USB 2.0 ports. This is a nettop motherboard, Giada MI-D525D. I'm getting this dreaded error when plugging webcam in. Posted: Sun 1:27 am Post subject: USB - device descriptor read/64, error -71 Gentoo Forums Forum Index Kernel & Hardware USB - device descriptor read/64, error -71 I can also confirm that this USB connection does power the board when plugged in.Gentoo Forums :: View topic - USB - device descriptor read/64, error -71 The only thing I can think of that on my end is that I'm using a Y-cable for my USB connection (I have a normal Mini-USB coming tomorrow via Amazon) since it is all I had. Any troubleshooting options for me? I've tried different USB ports and am, as of recently, plugging my board into external power (9V). So it looks like my board is not detected by my computer and I'm successfully uploading sketches to a meaningless port. I thought this was the right port because I remember not seeing it at first, but on second thought I had a permission issue at first (which is now resolved) causing me to not see the port.

I am uploading using board Leonardo, as recommended for my hardware, and the serial port /dev/ttyS0. This pin already flashes a few times (as mentioned before) on a reset, so I modified the delay times and still noticed no change. Please note that I don't have an external LED attached, but am looking at the board's LED on pin 13. I just uploaded the Blink tutorial sketch and it uploaded "successfully" but I noticed no differences. Turns out I wasn't right with that assumption. You, along with some people on StackExchange, have forced me to revisit the "fact" that I uploaded a sketch.
