Thanks, yes, but as I understand it, my tablet has USB host function. It can read/write to and from USB stick, External drive, V-Cam, camera, SD etc via USB host adapter.
Could it be a file-system difference?
Anyway, it means there is no way to transfer files without PC, which means PB360 is becoming obsolete, very sad.
One thing I will still try is transfering to/from micro-SD. Do not yet know if the formatting will be compatible. It may prove to be a work-around, but does not solve the original prob.
