Fixed Issues:
- USBSlaveFT232.a fix enumeration issue;
Add in latency timer get and set IOCTL functions,FTDI_SET_LATENCY_TIMER and FTDI_GET_LATENCY_TIMER were present but not implemented;
Improve data flow so data is passed faster and more reliably to and from the host;
Implement a dummy EEPROM to enable applications that require EEPROM checks to work.
- USBSlave.a correct remote wakeup behaviour when acting as a USB device and ensure correct ZLP generation for USB verification tests.
- BOMS.a implement changes for 64kB clusters on FAT16.
- FAT.a fix available cluster count.
- USBHostFT232.a correct baud rate settings for High-Speed devices. Added support for new FTDI devices.
- USBHost.a fix VOS_IOCTL_USBHOST_DEVICE_SET_CONFIGURATION to change the configuration of devices on USB host. Note: this will re-enumerate with the new configuration value.
- USBHostCDC code fix bitmaps for notifications.
Restrictions:
- FAT library will not support ATAPI disks.
- FAT library does not support FAT12 format disks. Please use FAT16 or FAT32 format.
- FAT fat_fileCopy function will only copy files to a different disk from the source disk.
- USBHostFT232 driver does not assert RTS or DTR automatically when flow control is enabled.
This must be done with an VOS_IOCTL_USBHOSTFT232_SET_RTS/DTR before data can be received.
