Have you tried to access a thumb drive? Does that work? |

Thumb drives work fine. They mount perfectly. USB floppies do not. For giggles, I tried a USB CD ROM and it goes into mount/unmount loop.Sent from my Verizon, Samsung Galaxy smartphone

1.4" may use different protocol UFI/CBI instead of supported BOT (thumbdrive). Which reader you are testing with, I don't have one but will try to see if I could get one easy enough. |

I order an 1.44mb usb reader to test with, it is not exact the same but is probably good enough. It may take 2 weeks for it to deliver. I will give it a try when I could manage the time |

yeah, it just got delivered, though I forgot to order an floopy disk to test with. But I am currently busy anyway, so please be patient. |

I am trying to read data from a 1.44MB USB Floppy Drive (Part number 19308801-19). TinyUSB seems to recognize it as an MSC but it does not mount it as a storage controller. What I mean by that is tuh_msc_mount_cb() is never called but tuh_mount_cb() is. Would anyone know how to manually mount it as an MSC? According to OSDev Wiki, I should be able to issue it SCSI commands to read and write from it so it should be compatible.
https://wiki.osdev.org/Floppy_Disk_Controller
"All USB devices, including USB floppy drives, are accessed indirectly (using SCSI-style commands encoded in USB datapackets) over the USB bus. USB floppy drives do not use any of the IO ports or FDC commands described in this article."
