If you have access to the UHD API, the property tree entry is
/mboards/0/link_max_rate.
So, something like
auto value =
my_usrp_object->get_tree()->access<double>("/mboards/0/link_max_rate")
will give you the maximum rate you can transport through your USB link.
Maybe that's actually what you're looking for, but otherwise it suffices
to figure out whether you're on High Speed or USB3 SuperSpeed.
Note this: The Property Tree is **NOT** UHD API! There's No Guarantee At
All This Won't Change.
Best regards,
Marcus
