Hi,
I am interested in the mecha comet (especially the I.MX 95 version for product design), but I would need at least 2 USB 3.0 ports. The spec sheet and website list :
But then the schematics (for the IMX 8P variant though) route as :
Which seems to imply that there is only 1x USB 3.0 and not 2. Which is also confusing since the pysical layout only shows 1 USB 2.0 and 1 USB 3.0 ports :
Could you confirm whether there is 1 or 2 USB 3.0 port on the comet ?
Hey!
The schematics are for EVT and will be updated once we move to production. This is what the final configuration looks like -
IMX95
USB 1 (Left-side, first) - USB-C SS 3.0, Host-mode only, Shared via Hub
USB 2 (Left-side, second) - USB-C HS 2.0, Dedicated, OTG, Display Port
USB Power (Bottom-side) - USB-C SS 3.0, Host-mode only, Shared via Hub, PD In/Out
IMX8M Plus
USB 1 (Left-side, first) - USB-C SS 3.0, Host-mode only, Shared via Hub
USB 2 (Left-side, second) - USB-C HS 2.0, Shared via Hub, Host-mode only, Display Port
USB Power (Bottom-side) - USB-C SS 3.0, OTG, Dedicated, PD In/Out
The reason for disparity is IMX95 has one 1x USB 3.0 and 1x USB 3.0 and IMX8M Plus has 2x USB 3.0.

Wow super nice !
Thanks for the clarification.
I’ll probably order a IMX 95 (need the more recent GPU and Vulkan support) and I’ll test if the shared USB 3.0 on hub have enough bandwidth for my use case later this year then.
Force to the mecha team in the meantime for the production and first commercialisation of the comet ! Looking forward to try it out !
Awesome! sounds good. Just a note, the bandwidth on the 3.0 is 5gbps, and the hub splits this for the two USB 3.0s ports, pogo pins and M.2 slot (for LTE). None of the USB from the hub is used internally. So unless you have data transfer devices on either, you should be able to get the full bandwidth.
Thank you!
