TUSB9261 maximum devices per bus ?

Other Parts Discussed in Thread: TUSB9261

I see in the datasheet the device uses up to 5 endpoints IN and 5 OUT.

That is a total 10 end points, but there's a limit of 64 end points on all host controllers I have seen so far.

It is also limited in all linux kernels - see XHCI_EP_LIMIT_QUIRK define in drivers/usb/host/xhci.h kernel source.

I also found out Windows has the same limitations.

If we don't use UASP (which seems to use extra endpoints) can we fit 16x TUSB9261 and the required hubs on the same bus ?

That is 5 hubs and 16 TUSB9261 devices in total.

Thanks.

Chris.
