However, in the "just works" department, your driver is seriously flawed since it only works for 32bit Windows. You have not provide 64bit drivers for them. For 64bit drivers to be used with 64bit Windows Vista and Windows 7, you also need to pay for the digital signature. Microchip is using custom drivers with MPLAB IDE but seems to move to WinUSB based drives under MPLAB X. You might want to consider move to either Microsoft's WinUSB (but it does not support Windows 2k) or the open source libusb-win32. We paid for the digital signature (from GlobalSign) to get libusb-win32 device driver to work under 64bit Windows Vista and Windows 7. It supports Window 2k as well. http://sourceforge.net/projects/libusb-win32/ Disclaim: I am one of the admins of libusb-win32 project. --=20 Xiaofan --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
