cannot connect usb camera over USB - C adb port

Jeff Delaune

What is the recommended configuration to run the FLIR Boson then, since it is listed in the feature matrix of the VOXL2? https://docs.modalai.com/voxl2-feature-matrix/#specifications

I am having the same issue as @Jagatpreet-Singh-Nir on the USB C with the Boson 640. It seems that I can get the camera recognized on the USB-A port of the VOXL USB Expansion Board, but then I can't use this port for the wifi dongle any more. USB hubs don't seem to work to split this USB-A port between the dongle and the camera.

Hi all,

I am also interested in connected FLIR Boson to VOXL2 - is it recommended to use the JST USB3.0 port on the 5G expansion board or the USBC/adb port.

Also if it is the JST port - are there any recommended breakout cables to purchase?

Lastly, do you know if the supported FLI Boson mentioned in the specifications matrix is the 320 or 640 - and if it was tested with USB 2.0

Hey all on thread, some updates here.

Main issue - USB-C as host not working yet on VOXL2:

This is my next top priority defect to resolve. I've put a couple days towards it but haven't cracked it yet, but am looking back shortly.

Recommended configuration for Boson connection:

If you also need two USB ports, then this board (the M0090 carrier board only) which has:
- a 4 pin JST connector, USB2.0, possible cable is to use is MCBL-00009 or you can make one pretty easily
- 10 pin JST connector, USB3.0, we are posting a new MCBL-00022 soon which is a 10 pin JST to USB3 (within a week likely) or you can make your own
if just 1 USB port, then we have a smaller M0078 USB debug board
if just 1 USB port AND you want to add an applications processor UART port on 4pin JST, we will have a new M0125 up online shortly, which I think is pretty cool!

Using out of the USBC connector will prevent you from adb access.... so in a vehicle if it's permanently mounted there (and assuming I get the fix!) then you could prevent ability to flash it later on if needed or to troubleshoot, but if that's no issue then I'll update you ASAP when I have updates on this.

Which Boson?

we tested with the 640 over USB 2.0 and voxl-streamer

Thanks @modaltb . Do you know if the MCBL-00022 cable is still planned to be released this week?

@modaltb Did you ever have any luck resolving the USB-C host issue for the VOXL2? Has an update been released that includes this fix?

modaltb

Hi @wijone we have not unfortunately. It's still an open item to resolve, but as there's a work around using above, we've not put a resource on this particular issue at this time.

Hi,

I'm interested in connecting the lightwarelidar sensor(SF45/B) to VOXL2 using USB C too.
I tried two settings to connect to the VOXL2 of the Sentinel drone.

LiDAR - (Micro-USB 3.0) - USB hub(USB C) - VOXL2
LiDAR - (Micro-USB 3.0) - USB hub(USB C)
- USB hub(USB C) - VOXL2 (for power)
- USB hub(USB C) - USB A - 4pin JST connector - Microhard Modem

After connecting, I did the lsusb command, but couldn't see the device.
If connecting to a microhard modem using a 4-pin connector is the right way to use a LiDAR sensor, I wonder what port names are available in the /dev directory.
If not, is there a recommended configuration for the LiDAR connection to VOXL2?

Thank you

I was looking this up the other day and stumbled across this forum thread. I have a high frame rate (90fps+) camera from Allied Vision that works across the USB 3.0 bus, but using the USB-C port would be much easier for integration. Just checking in to see if there had been any progress on using this port for high data rate cameras, etc. Thanks!

HI @jdott ,

At this time, no we don't have a SW solution to get the USBC port as a host.... so the USB3 approach warrants an add-on board like this on

@modaltb

Hi there, just checking in if there have been any updates to this and whether the USBC port can be used for connecting peripherals. We have multiple USB devices and this would greatly simplify our integration.

Thanks

@msberk It cannot. This is a hardware limitation in VOXL 2 and will not be fixed without a hardware revision.

@Moderator Thanks for the clarification, we will not expect a solution to this then.
