Hey Guys,

first to the specs:
i am working on Win 7 with LPCXpresso V7.6.2. The used processor is a LPC1769.
For the USB communication i use the LPCUSBLib v.098.

My target is to generate a "virtuel" Massstorage Device on the internal RAM.
This works so far that the Device shows up under Windows. If i open the Device it also shows the three files i generated on the device.
The files got a Size of 512B (which is although correct).

The Problem is when i open the Device it runs into an endless loop. The while-loop is located in Endpoint_Read_Stream_LE

I think this topic is about the same problem:

Has somebody an idea what could be the problem?

I wish a happy New Year.

Best regards
Patrick
