I just tried it using an RP2350 connected to a PC running Linux Mint Mate edition. I can copy files to the 2350 file system using either the GUI or command line and they give the appearance of being copied successfully. I can read them back. However, if I eject the USB drive and restart the RP2350 processor the files have gone away. So either they are being cached in the PC or they are only transiently stored. John
