Yes, I know wwan + ssd device supports only USB2.0 … and mc7304 is USB 2.0 whilst mc7455 configured to USB 3.0 but has backward configurayion to USB 2.0. Someone did mentioned mc7455 working fine on x301 by tapping #23 through #33 but no luck foe me on x220t. Any other valuable inputs how to resolve this problem ? …
