4.1 USB Command Set Description (USB Descriptor)
The USB HOST detect USB mouse plug-in and assigns a new unique address to the USB mouse, then ask USB mouse device for information about the device description, configuration description, HID report description during enumeration period. After enumeration, the USB device is transfer motion and button value to the USB host.

4.2 USB Data Report Format
The USB report has two data formats, depending on boot or report protocol is selected. One kind of data format is the boot protocol used in legacy environment as 4.2.1. The other kind of data format is USB report protocol format and sends the additional wheel movement data in the fourth byte as 4.2.2. The wheel is moved forward the fourth byte data is 01H, the wheel is moved backward the fourth byte data is FFH, and the wheel is idle the fourth byte data is 00H.
4.2.1 USB Boot Protocol for Legacy Operation
Byte Bit Symbol Description
0 BL 1 = Left button pressed
1 BR 1 = Right button pressed

E-mail: fae_service@pixart.com.tw V1.0, APR. 2005 7. NSTL Compatibility Test PAN3501UI has passed the NSTL Compatibility Test Program, which conducts an objective quality assurance test suite to verify correct operation, functionality, and compatibility of system products. "The NSTL standard testing methodologies assessed the compatibility of PAN3501UI at the NSTL/ALLION Labs testing facility. And, it shows that it is getting along great and operated correctly with various software applications and add-on devices under a variety of Operating Systems." cited from the NTSL Test Report. Accordingly, PAN3501UI fully meets NTSL Compatibility Test Standard and is able to carry the NTSL Seal. 8. Update History Version Update Date V1.0 Creation, Preliminary 1 st version 04/06/2005
