http://www.hitex.co.uk/hcc/ EUSB is an embedded usb device stack with drivers for MMC/SD, NAND Flash or Atmel DataFlash. It can be combined with the EFFS-FAT system to allow data storage and retrieval from both the embedded controller and the PC through USB Mass Storage. Royalty free ANSI C source code for AT91SAM7S, LPC2148, and STR71x processors.+

http://www.alfat.co.uk/usbwiz.html Through simple commands over UART (921.6 K-baud), SPI (7Mhz) or I2C (400Khz), you can read/write files in FAT 32/16/12 from your thumb drive or SD/MMC card. Accessing USB Human Interface Devices (HID) and USB printers is also as simple.
- 40 to 50 mA, power consumption with low power mode.
- Single supply 3.3V with 5V tolerant IO pins.
- Cost: Chip 25pounds (~$38), dev kit 40pounds (~$60).
- Supports Low (1.5Mbps) and Full (12Mbps) speed USB.
- Supports Control, Bulk, and Interrupt Transfers.
- Provides 2 physical USB ports and 2 device handles.
- Can open 8 pipes/file handles at once.
- Easy commands like "CD","MD","RD" for change, make, remove directory; "OF","CF","RF","WF","SF","FF","DF" for Open, Close, Read, Write, Seek, Flush and Delete File.

miSim DE is an excellent, portable and powerful IDE for developing PIC applications.
The only consistant, simple to use yet powerful development environment. It simulates real-world devices via virtual component "plugins" (LED,LCD,key,motor,TV,etc) in real time, has a syntax highlighting editor, macro assembler and disassembler. Regular updates and third-party plugins keep this software ahead of any other PIC IDE.
