Looks to be like you're still using a UHD 4.2 environment on your Ubuntu
machine.
You want to be compatible with the 4.1 environment on your
Windows/MATLAB machine.
Those assertion errors are due to, I think, you not specifying a device
type on the uhd_usrp_probe,
so the library goes through "device discovery", and since you don't
have a USB-connected USRP
on the system, that part of discovery is failing.
Try:
uhd_usrp_probe --args type=x300,addr=192.168.10.2
And share the output, including the start-up messages that give version
information, etc.
