    You know Bill, all the times I have visited your GitHub repository I never took the time to check it all out. Was usually checking or getting SdFat. It's interesting that you called it UsbFat because that is what I...

    HI Bill, I am really anxious to try this out with the two versions of SdFat that I am working on for MSC. I have two versions of SdFat that I have modified adding my USB Host Mass Storage driver to them as a block...

    No it is not Bill Greiman's current SdFat-beta it is a modified version of it that I forked from Paul Stoffregen's repository. I am in the process of adapting MSC to use SdFat as well as FatFS. But again this is work in...

    I have just tested a 128GB USB thumb drive without a problem. In the past several people as well as myself have tested with several different types of USB Mass Storage devices. The size of the device really only...

    First of all mscFS is for use with my version of SdFat-parallel which is a version of the Teensy file abstraction 'FS.h' being developed right now and is just an experiment with using MSC and SdFat. This is not usable...

    You were right:) I know I copied and pasted to both usb_desc.h files but obviously did not save the changes. That's what I get for staying up late and trying to do stuff. It now compiles and uploads but still will not...

    @WMXZ Missed this step last night. I updated boards.txt. Now 'MTP Disk SERIAL (Experimental)' shows up in the tools menu. Also for this: permission denied for device '/dev/hidraw0' I searched for this on the...

    I think I was probably still a little vague on how to setup these libraries. My repository of Paul's SdFat-beta has three branches. I would suggest downloading the zip files instead of cloning and then rename the one...

    For anybody that may have tried these libraries there was a major bug in both of the SdFat-inline and SdFat-parallel branches of my USB driver for SdFat-beta. I used a global variable (thisDrive) instead of a private...

    @WMXZ @defragster -I think i misunderstood what @fluxanode was after. I thought he wanted a version that just used SdFat2. The readWrite.ino works fine with the Sd library which is what FS is about and is the preferred...

    Here is an example of write/read with SdFat 2.0 beta. As I have been working with Arduino 1.8.13 and TD 1.54B5 I have used the new SD library and the tweaked version of Sdfat. A lot of testing has been done so far with...

    I ran into the same situation using SdFat with bench.ino. The size of the file was not consistent and could not determine the end of file. It would change. If I am not mistaken file size of the file and EOF should be...

    I now have SdFat-beta and MSC working together two ways. One way uses a heavily modified version of the SdFat and Sd libraries. I matched or in-lined the the classes in the two libraries and added block device access...
