I tried mounting the /dev/hd1t12 but get the same error, oddly, fdisk reports this as FAT32, not DOS, but I tried formatting the SD card to DOS using both a Mac and fdisk on QNX, and get the same error. fdisk is quite able to look at the SD card and reports the size correctly. It can format it too, so I think the USB Mass storage driver is working fine, I’m just trying to access it in the wrong way or something. Incidentally, when I tried to run ‘devb-umass cam pnp’ with the Muvo plugged in, the OS crashed, Caps lock did not work, so I think it was a full OS crash, not just Photon. Maybe this is just ‘one of those things’ or maybe it indicates a problem with my USB, but I thought I would mention it. Although after restart, it did not crash on running devb-umass.
Thanks for the help
Garry
