Re: VSMD001 module and slow USB Response

Here are some screens from the windows event log, I see paging error.
Maybe is a drivers error because the pc runs windows 10 with generic chipset drivers ?
Only vlsi have this error , other usb flash drivers, or when I put the sd card on usb with adapter it works fine

Re: VSMD001 module and slow USB Response

I use a micro SD card 8gb , with FAT32 formated on windows 10.
If I use the module with internal 16mb flash , I have the same behavior.
I can format the sd card at FAT12 or fat16? or do you recommencement an allocation unit size ?
