No available USB device found with matching PID/VID

#1

Hi
I've just got the Axoloti Core board. I'm relying on the usb as the power source. When I connect to OS X 10.10.2 the LEDS blink and settle on the green light. When I go to 'Board Menu' and select 'Select Device' there is no device showing. The dialogue box shows this message:

No available USB device found with matching PID/VID

I replaced the micro usb cable to one that I know for certain transfers data - even so, no result.

Any ideas?

Thanks

The symptoms you're reporting could be caused by a power-only USB cable, but you have already verified, great!

The next thing to exclude is anything related to firmware.
Could you try a "rescue flash": remove power from Axoloti Core, and then connect the micro-USB port to your computer while holding button S1. The LEDs will stay off when in DFU mode.
Then select in the Board menu -> Firmware -> Flash (Rescue)...
If the LEDs stay off, but you still get "No devices in DFU mode detected.", then this is probably an unknown hardware error...

Hi Johannes
the 'rescue flash' did the trick. thanks for stepping in so quickly to help. I've sent a patch to the flash and it plays independent of the computer. now i need to start figuring out the patcher environment. looking forward to this project. Thanks again!

I am currently getting this error. I tried the S1 button trick, and it still says "No devices in DFU mode detected." Could my board have gotten damaged somehow?

#5

I need a bit more context/info: any led activity when powered up without pushing S1? Can you confirm the USB cable is not a power-only cable?

#6

Nevermind, I fixed it! Bad cable, went out and bought a new one.

#8

I have the same issue on osx 10.7.5/mbp a1211. Leds blink during startup and set to green. But I have "No available USB device found with matching PID/VID" message.

Tried axoloti on pc with win10, and it works great. Usb cable is the same.

#9

Do you see anything related to Axoloti Core, if you go to System Information -> USB?

#10

I reinstalled osx(with all updates) on new ssd, and now everything works fine.

#11

I have no idea what was causing this, as there is no driver to install on OSX, still happy to hear everything is working now.

Hello Johannes,

I just received my Axoloti today, and unfortunately am getting connection issues on Windows 7. It appears that the drivers and software are installed correctly.

However I'm having a similar issue as this thread, and also tried the DFU mode and got the error:

No devices in DFU mode detected. To bring Axoloti Core in DFU mode, remove power from Axoloti Core, and then connect the micro-USB port to your computer while holding button S1. The LEDs will stay off when in DFU mode.

You mentioned it "is probably an unknown hardware error". Can you elaborate?

Here is the output I get when first starting the software:

Axoloti version : 1.0.12-0-g80370d2 build time : 02/02/2017 20:39:14 CET

Any advice would be appreciated.

Thank you,

if this is a new Axoloti , that you have only just plugged in, its unlikely to be hardware issue.
(as Johannes has various tests he runs on the board, and I think this includes uploading the firmware - iirc)

first thing I would check is the usb cable, be aware many micro usb cables are power ONLY, used for charging , you need one with data... so try different cables.

also what is happening with the Axoloti leds when you power up,
both when you don't press S1, and when you do.

#14

Actually I tried the Axoloti on a Windows 8 and all is well - effortlessly! So the cable and the Axoloti are fine, and it appears to be a Windows 7 issue. So even though the drivers appeared installed after plugging it into my computer (this was after software installation as per instructions), I still get the error. It appears to be a Windows 7 compatibility issue?

#15

Hmm, with windows 7 , it appears you still have to run Zadig to install the winusb drivers.
If you search on this forum, you'll find references to it.
( for some reason I thought this was no longer the case, but alas still appears to be required for some users)

#16

I think I am experiencing some issues related to these previous comments. Just received my Axoloti and can not get the patcher software to work.

Problem : Axoloti board turns on when connected to computer. Leds flash. Windows installs driver and says it's ok. When I try to run software I get "No available USB device found with matching PID/VID".

Things I have tried:

  • tried 4 different usb cables, verified they are data cables.
  • tried on multiple usb ports, 4 on one computer 5 on another.
  • axoloti_runtime installed to C:\Program Files (x86)\axoloti_runtime
  • tried on 2 different Windows 7 computers.
  • in axoloti software under -> Board -> Axoloti Core shows up but says "not accessible, driver not installed"
  • Put board into Rescue mode by holding down s1 and plugging in. In Zadig application chose
    STM32 Bootloader -> "Replace Driver" - > error " The driver Installation failed"

Not sure what else to try. I will note that regardless of what combination of computers and cable same exact errors exist. Seems to be a board problem?

#17

have you installed winusbcompat drivers?
its worth reading through this thread, as it covers issues other windows 7 users have had in the past.

#18

Trying to install this winusbcompat drivers. I tried to update the driver(one found from the thread you provided) and it says I already have the latest version. I then uninstalled the current driver and reinstalled using winusbcompat drivers. still getting same error message in axoloti software.

Hello,
it's been a while since I last used my Axoloti.
I installed anew (had it installed before on my system, which is Ubuntustudio, Ubuntu 16.04.3 LTS)
I get the infamous "No available USB device found with matching PID/VID".
this is what I tried so far:
* connect Axoloti holding S1 button, in dfu mode (no LEDs flashing) and then Board/Firmware/Flash (rescue) -> "No devices in DFU mode detected."
* connect Axoloti normally (LEDs flash, green stays on) and then Board/Select device, click "refresh" -> no device appears
Any suggestions what to try next?

#20

its probably sulking because you haven't been paying it enough attention :wink:

hmmm.. odd though, theres no reason it shouldn't at least turn up as a DFU device.
really you need to proceed as you would with any other usb device on linux...
- try a different usb cable (make sure its a data cable, not just power)
- dont use a usb hub, try to eliminate any other possible issues
- check logs and device mapping using dmesg and lsusb ,
- check udev rules. (though this wont stop it appearing)

when checking the logs, what you really want to see is if any device is being seen by linux.
even if a device is completely unrecognised by linux, it should still appear on the device tree and something come up in the console logs.
if its not, then that sounds like hardware/cables ... if something does appear sounds more like OS/firmware.

Id also connect it to a mac or windows machine and see if that can see it in either mode... to determine if its a hardware issue, or just your linux setup. (mac is preferable, as has less variables than windows :wink: )

you could also try holding down S2 whilst booting to see if it then appears to work in normal mode (this prevents any auto start patch loading) , but frankly it sounds like you have a USB connection issue... either due to OS configuration or bad cable/hardware

#21

Thank you thetechnobear,
In my rusty Axoloti skills, I forgot to think about one possibility you mentioned, this Axoloti had an auto start patch in internal flash. So the holding down S2 did the trick!
