I bought two M7s one of them seems to be working and the IDE can connect to it and windows recognizes it fine.
The other one isn’t recognized by windows when using the same USB cable. It just says that the USB device isn’t recognized and to try to plug it in again.
Mmm, okay, try to put it in DFU mode. If that doesn’t work there’s an issue with the USB connector…
(This is second time we’ve gotten a customer saying the USB connector is bad - for the next OpenMV Cam production run i will require each cam to be plugged into a PC before it passes Q.C. versus it just passing Q.C. with our programming jig…)
To put the camera into DFU mode do this:
And then plug it into your PC and you should see a DFU device (in windows):
If that doesn’t work please send us an email with your shipping address, phone number, and receipt, and we’ll send you a replacement.
I’ve just received the OpenMV M7 camera and it does not enumerate, both in normal operations and in bootloader mode.
I’m running Ubuntu 16.04 and I work with several STM32 microcontrollers without any problem in enumerating their USB ports, here the dmesg output after I connect the camera:
[1476382.168489] usb 3-4: new full-speed USB device number 75 using xhci_hcd
[1476382.168637] usb 3-4: Device not responding to setup address.
[1476382.372633] usb 3-4: Device not responding to setup address.
[1476382.576473] usb 3-4: device not accepting address 75, error -71
[1476382.576514] usb usb3-port4: unable to enumerate USB device
New H7 not mounting on Ubunut 18.04/MAC OSX 10.14/windows 10
Although I see LED light flashing green on connect and then flashing blue but it does not show up on the system.
I tried the following steps mentioned in this thread and still do not see any device under the USB controller on window
The camera has power, so it’s either the USB connector on the camera is faulty or the cable doesn’t have provide data, just power. There are a lot of USB power only cables out there now.
Oh damn YES! You are right. I thought I was using the right one … I firmly believed:?
anyway i just plugged a good usb-data into my h7 cam and everything looks fine
sorry my bad.
thanks
