I have exactly this issue but with LPC51U68:

Grant Trebbin: "The directory name is invalid" on the NXP LPC19459 in USB mode 


TLDR; When ISP invoked in windows 10, the CRP DISABLED mass storage shows as a device in the device manager, but the storage is not accessible. It just says "The directory name is invalid". On linux it works fine.


Has anyone dealt with this issue or found some workaround on WIN10 to make it work? 

Having customer to boot linux to update firmware is kind of clumsy


Thank you!
