System requirements: 
1) Pentium based PC or power PC based Macintosh with available USB 2. 0 port
2) Mac/Windows OS with USB 2. 0 support

FEATURES:
- Compliant to USB specification Revision 2.0
- Support 4/3/2 downstream ports by I/O pin configuration
- Upstream port supports both high-speed (HS) and full-speed (FS) traffic
- Downstream ports support HS, FS, and low-speed (LS) traffic
- 1 control pipe (endpoint 0, 64-byte data payload) and 1 interrupt pipe (endpoint 1, 1-byte data payload)
- Backward compatible to USB specification Revision 1.1
- On-chip 8-bit micro-processor
- RISC-like architecture
- USB optimized instruction set
- Performance: 6 MIPS @ 12MHz
- With 64-byte RAM and 2K mask ROM
- Support customized PID, VID by reading external EEPROM
- Support downstream port configuration by reading external EEPROM
- Single Transaction Translator (STT)
- Single TT shares the same TT control logics for all downstream port devices. This is the most cost
effective solution for TT. Multiple TT provides individual TT control logics for each downstream port.
This is a performance better choice for USB 2.0 hub. Please refer to GL852 datasheet for more
detailed information.
