I have problems getting the USBMSB_Ramdisk_kl25z to operate properly
I compiled and downloaded the program into a FRDM-kl25z card and when I connect the kl25Z USB port to a Linux computer the df command doesn't show the drive.
When connecting to Windows it shows up as F: and after long delay opening it shows file name README.TXT that can't be opened error text box = "F:\README.TXT directory name is invalid" properties shows as 0 bytes used & 0 bytes free.
Linux is Ubuntu and Windows is Windows 7
