No available USB device found with matching PID/VID

#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!

#22

excellent, happy your back to patching.... still a bit surprised S1 didn't get you into DFU more.
anyway, great news your up n running again :slight_smile:

#23

I am on a Mac too Axo had been working fine up until today,

I have gotten the No available USB device found error and followed the advice in this thread
and got this:

Then I hit compile by mistake and pressed s2 and got this:

I don't know what I have done, please help

#24

Update, I have plugged it into another mac and it connected, but now seems to have very low audio output, will keep investigating, but if anyone can shed some light on what is going on I would be very thankful

#25

the issue you are having is it cannot find /Applications/Axoloti.app, though Ive never see it expressed this way before...

Id check your install on that mac..

what cables have you connected , is this a v1.0 board? if so you need to use a stereo cable.
see, https://sebiik.github.io/community.axoloti.com.backup/t/axoloti-hardware/59

also be careful you don't put it into a balanced input.. otherwise L&R might cancel each other out (almost) on some patches. thats IIRC correctly... I remember doing something like this when I first got axoloti, but it was a long time ago now... so perhaps im mis-remembering :slight_smile: ... there are now 'audio config options' to resolve this , but id recommend initially just checking your cabling, so you identify the source of the issue.

otherwise perhaps its something with the particular patch your using?
perhaps check the headphone output, see if its the same.

#26

Thank You TB, Everything seems to be above board now, I had a dodgy stereo cable, and have replaced it, the volume output does seem lower but, I think that may just be paranoia. I have a version 1.2 board and have checked multiple patches they are all the same volume, so its possibly just my perception.

I will try reinstalling on my mac. Thank you again for your ever present and useful help

#28

Hi everyone,

After having the same problem mentioned above with the inability to do the "flash(rescue)" thing I opened the enclosure to find that some components are really hot, specially IC2 and IC1.
The LEDs are working like other users in this thread so I assume my Axo its not bricked already.

Also, I've tried 3 different USB cables with no luck as well as reinstalling the software.

Any tip would be great.

Thank you all in advance

#29

check the various threads, ive details many times what to try and check...
you should try the S1 during power cycle, and see if the board appears in DFU mode.
if it doesn't appear at all in your USB list , then either
a) your cable is no good
b) you have bricked your axoloti

if the later PM Johannes.

#30

hi everyone, i had some of the issues that you are talking about. Im on windows 7 (64) besides of the "matching PID/VID" bug, if i update the Axoloti Core driver with zadig then gives me the java bug (that i thougth that have been solved by updating java) anyway, if someone have any other recomendation besides unplug/plug - update drivers with zadig - go to dfu and flash (Recover). Cheers.

#31

Hi, I am on Ubuntu and getting the same PID/VID error. I would like to try deleting the startup patch using S2 and/or going to rescue mode using S1, the only problem is, I have no idea where these buttons are and have been scratching my head trying find them with no information online which seems to explain. Can someone tell me where I can locate these buttons on the keyboard? Thanks. :smile:

#32

The tiny buttons are next to the MIDI jacks, and marked on the bottom of the board.

#33

Oh wow! Thanks so much!

#34

Hi,
First i'm sorry fro my bad english...
I'm trying to run my axoloti board but i've any problems.
When i try to connect and run the patch this error is displayed: No available USB device found with matching PID/VID

I've tried to run in DFU mode pressing the S1 button but this message is displayed:

No devices in DFU mode detected.

The fact is i've already test the USB cable with my phone to save any files and it's working... By the way i'm on Mac osx (hight sierra)
So i really can't know what is the problem and searching on this english forum is a little bit difficult for me cause of my english first and my bad informatic's knowing...

I would be gratefully if you can share a path to follow ! :slight_smile:

#35

Hi paitoquet,

When you plug in the board, do the two LEDs in the front blink? The two LEDs next to S1 and S2 should blink red and green when first plugged in.

#36

Yes, the two LEDs blink!

#37

If the LEDs come on, something is working. That is a good start.

Does the SD card have anything on it? If you plug the SD card into a card reader, try backing the card up, erasing it, putting it back in the Axoloti, and see if that works.

#38

Just to second what hitachii is saying, can you startup normally with the SD card removed, just troubleshooting but it could be that your SD startup patch is causing an issue, so just to rule that out.

Also how are you powering the axo, just by USB or external power?

Have you got anything soldered to the board/Gpio’s?

Also just having read about my own issues earlier in this thread, can you try using it on another computer, again that could help isolate where the issue is occurring, I was able to use another macbook with success.

#39

Thanks you both for your answers,
So, first i tried without SD card and the problem was already there. I've just tried with an SD card empty and it's the same problem.
My axoloti is alimented just by the usb cable and nothing is soldered to the board.
I'll try to connect with another computer as soon as i could!

#40

Good try on another machine, also forgot to mention have you tried holding s2 on startup?

Is the axoloticore new or have you bought it second hand?
Have you successfully used it in the past or is this the first time you are trying it?

Also just quoting Johannes, try another cable, at this point you're just trying to rule out potential areas of issue, because as from below if it's an unknown hardware issue, who knows what the cause will be....
