But does Win2k use a custom driver for this device? If so you need to reverse engineer the protocol used to talk to the device. If you want, try using the generic usb-serial driver. You can pass your product and vendor ids on the command line when loading the usbserial driver (I would give you the exact command, but you censored the P: line of your file :) The usbserial driver will send data through the bulk in and out endpoints with no translations, which might be good enough for you to get started. Also, try running USBSnoopy on the Windows driver to see what the protocol looks like, to see if it really matches the ACM spec or not (odds are it doesn't, otherwise the device would say it does.) thanks, greg k-h _______________________________________________ [EMAIL PROTECTED] To unsubscribe, use the last form field at: https://lists.sourceforge.net/lists/listinfo/linux-usb-users
