We are using MQX 3.8 on a K70, internal USB Full Speed. The K70 is set as the Host and reading a file from a USB Flash Drive using the MQX MFS File System. The file is a binary file about 2MB in size. It takes 7-8 seconds on a few drives to load the file, but on most drives it takes 40-60 seconds. This seems really slow for a Full Speed USB connection..?
