Minimig+USB floppy drive question?

[kvasir]

I had a question about Minimig, and was hoping somebody more familiar with the hardware involved would be able to answer. I have an old USB-base external floppy drive, and was wondering if a custom USB port could be adapted to the Minimig for floppy access? I know that Amiga floppies have 2 "zones" on them, because of a variable speed on the read/write head. I'm not too familiar with standard USB floppy control, and don't know if it would be possible to either adjust the USB floppy drives read/write speed or even the disk motor speed at the sector that the Amiga disk's magnetic media would change "density"? And if USB offers that kind of control, a DD or HD Amiga floppy were could be read directly as DF0:, instead of (from what I understand) a .adf file from a SD card?

Interesting that, wasn't sure what would be required to adapt the usb floppy. Looks like more effort than its worth, though I also have an external Amiga DD floppy drive, A1000 vintage. (It has the color checkmark logo on it, even), might be easier to rig that up. The usb idea was a bit more attractive to me due to the external USB floppy drive I originally bought for my laptop is really slim, and more portable than the old A1000 drive. Another about the USB drive, though. Would it be possible to burn another ffpga or flash rom to replace this ASIC controller chip, or is this not standard enough to be worthwhile?
