==== SUMMARY ====
Source Path: Repository: License:
------------ ----------- --------
usb_flashdrive/lib github.com/felis/USB_Host_Shield_2.0 GPLv2 or later
usb_flashdrive/lib/masstorage.cpp [1] github.com/greiman/UsbFat MIT
usb_flashdrive/lib/settings.h [1] github.com/greiman/UsbFat MIT
[1] Changes related to SKIP_WRITE_PROTECT and DELAY only
==== USB HOST SHIELD 2.0 LIBRARY ====
The lib/ folder contains a subset of the files from the USB Host Shield 2.0
library:
https://github.com/felis/USB_Host_Shield_2.0
While the original library was released under the GPLv2 and could not be
commingled with Marlin, the developers have graciously re-licenced the
files needed for Marlin as "GPLv2 or later", as documented in this thread.
https://github.com/felis/USB_Host_Shield_2.0/issues/364
Small modifications have been made to the source. Please search for
USB_FLASH_DRIVE_SUPPORT or look at the patch file to see what was changed.
==== PERFORMANCE ENHANCEMENTS FOR USB DRIVES ====
There are also some small performance enhancements from Bill Greiman, regarding
SKIP_WRITE_PROTECT and DELAY. These changes came from the following repo:
https://github.com/greiman/UsbFat
While the original library was released under the GPLv2 and could not be
commingled with Marlin, the developer has graciously re-licenced his changes
under the "MIT" license, as documented here:
https://github.com/greiman/UsbFat/issues/8
==== MARLIN INTEGRATION WORK ====
All additional work done to integrate USB into Marlin was performed by AlephObjects, Inc.
and is licensed under the GPLv3.

* This is broken. We need to enumerate differently.

* Oleg - I wouldn't do anything before the newly connected device is considered sane.
* i.e.(delays are not indicated for brevity):
* 1. reset
* 2. GetDevDescr();
* 3a. If ACK, continue with allocating address, addressing, etc.
* 3b. Else reset again, count resets, stop at some number (5?).
* 4. When max.number of resets is reached, toggle power/fail
* If desired, this could be modified by performing two resets with GetDevDescr() in the middle - however, from my experience, if a device answers to GDD()
* it doesn't need to be reset again
* New steps proposal:
* 1: get address pool instance. exit on fail
* 2: pUsb->getDevDescr(0, 0, constBufSize, (uint8_t*)buf). exit on fail.
* 3: bus reset, 100ms delay
* 4: set address
* 5: pUsb->setEpInfoEntry(bAddress, 1, epInfo), exit on fail
* 6: while (configurations) {
* for(each configuration) {
* for (each driver) {
* 6a: Ask device if it likes configuration. Returns 0 on OK.
* If successful, the driver configured device.
* The driver now owns the endpoints, and takes over managing them.
* The following will need codes:
* Everything went well, instance consumed, exit with success.
* Instance already in use, ignore it, try next driver.
* Not a supported device, ignore it, try next driver.
* Not a supported configuration for this device, ignore it, try next driver.
* Could not configure device, fatal, exit with fail.
* }
* }
* }
* 7: for(each driver) {
* 7a: Ask device if it knows this VID/PID. Acts exactly like 6a, but using VID/PID
* 8: if we get here, no driver likes the device plugged in, so exit failure.
