Hi,
I’ve three (3) modules where two (2) MC7455 and one (1) EM7455 modules and currently tested on DELL 7250 and LENOVO X220/X220T running Windows 10 Pro 64 bit and Ubuntu 17.04 (dual boot). On DELL 7240 I’ve tested for MC/EM7455 (internal + m.2 to mPCIe) and for LENOVO X220/X220T where both are installed using mPCIe to USB converter.
