Did you look for drivers on the Lenovo site?
Sure did!
Entered all the model/type/subtype etc data.
Showed up a driver for the Ricoh SD/MMC device.
Downloaded, followed the README, installed without complaint. Mandatory reboot.
The device page still shows missing driver.
It's over 50 years since I joined IBM as an engineer and I'm sure that some software (I'm looking at you Microsoft!) gets worse as the years go by.....
