SDIO + SD Card + USB MSD .....Windows Problem

JCorn.2

Hey everybody,

I just got it working that I can use my SD Card as an USB MSD. I can write, read and delete files. Everything looks good.

The only problem is that when I connect the USB cable to my computer it takes like 2-3 minutes until the SD card is visible in the explorer. Furthermore, Windows popup window tells me that there is a problem with the mass storage device. However, everything works fine after that. There is not really a problem.

The only problem is that it takes so long until Windows displays the SD card.

Does anybody have an idea why?

I would really appreciate your help!
