GUI M1 Mac not recognising sensor

[Samuel Wallace]

Hi,

I am trying to use the DV GUI to connect to my DAVIS 346, however it cannot seem to find the device when it is plugged in. I am on an M1 Mac, when I run iosgrep, I can see the sensor

ioreg -p IOUSB -l | grep -A 10 "DVS 132S"
  | +-o DVS 132S@01200000  <class IOUSBHostDevice, id 0x10002e05b, registered, matched, active, busy 0 (21 ms), retain 23>
  |     {
  |       "sessionID" = 7013136200948
  |       "USBSpeed" = 4
  |       "idProduct" = 33822
  |       "iManufacturer" = 1
  |       "bDeviceClass" = 0
  |       "IOPowerManagement" = {"PowerOverrideOn"=Yes,"DevicePowerState"=2,"CurrentPowerState"=2,"CapabilityFlags"=32768,"MaxPowerState"=2,"DriverPowerState"=0}
  |       "bcdDevice" = 774
  |       "bMaxPacketSize0" = 9
  |       "iProduct" = 2
--
  |       "USB Product Name" = "DVS 132S"
  |       "locationID" = 18874368
  |       "bDeviceSubClass" = 0
  |       "bcdUSB" = 784
  |       "kUSBSerialNumberString" = "00000046"
  |       "USB Address" = 1
  |       "IOCFPlugInTypes" = {"9dc7b780-9ec0-11d4-a54f-000a27052861"="IOUSBHostFamily.kext/Contents/PlugIns/IOUSBLib.bundle"}
  |       "UsbPowerSinkAllocation" = 240
  |       "bDeviceProtocol" = 0
  |       "USBPortType" = 5
  |       "IOServiceDEXTEntitlements" = (("com.apple.developer.driverkit.transport.usb"))
--
  |       "kUSBProductString" = "DVS 132S"
  |       "USB Serial Number" = "00000046"
  |       "kUSBAddress" = 1
  |       "kUSBVendorString" = "iniVation"
  |     }
  |
  +-o AppleT6000USBXHCI@02000000  <class AppleT6000USBXHCI, id 0x1000003b6, registered, matched, active, busy 0 (3045 ms), retain 103>
    | {
    |   "IOClass" = "AppleT6000USBXHCI"
    |   "kUSBSleepPortCurrentLimit" = 3000
    |   "UsbHostControllerSoftRetryPolicy" = 0


When I run 

 system_profiler SPUSBDataType
It doesnt appear.

Any suggestions welcome

Thanks!

Hello,

something appears to be very wrong there.

The device identifies as a DVS132S (Produc-ID 0x841E), which was an experimental internal model, none of which have ever been sold or left the lab.

In fact recent versions of DV don't recognize it at all, which is why you don't see it listed.

When/where did you get this camera? Can you send us a picture, especially of the front without lens so the sensor is visible?

There's a chance the wrong firmware was flashed to an actual DAVIS346, but this would be the first case of that happening I'm aware of.

Thank you for the report and have a great day!
