updated 12-1-05 The device driver and DLL in this folder must be used together. The driver must be be placed in: \YourWindowsDirectory\system32\drivers\ and the DLL must be in the same folder as your application. The .INI files belong in your Windows folder. LL_USB.INI is required for running, but the M30x_SP.ini file is for user convenience only. Tip: Copy LL_USB2k.dll, LL_USB2k.sys, LL_USB2k.inf, and LL_USB2k.ini onto a floppy diskette for the installation process for the first time you connect one of the M30x devices to your system. Installation may also be required if you connect to a USB port that it wasn't previously connnected to.
