I posted the following message two day ago in comm-dev-forum but did not receive any response. Sorry for reposting the message in palm-dev-forum but I desperately need this info. Here is the message: Hi, I made a program which makes a USB connection between Handspring Visor and PC. It uses USB driver installed by Handspring Desktop and was based on the example provided by Handspring. Recently I installed the new Palm Desktop 4.0.1 which has USB support. Hotsync with Visor works great but my program does not. My question is: Where can I find information about USB driver installed by Palm Desktop 4.0? I need GUID of the driver, and supported IOCTL codes, especially IOCTL_BULKUSB_START_POLLING and IOCTL_BULKUSB_STOP_POLLING.
