No, I don't think so. Not in it's current form. Currently, usbtouchscreen doesn't have any means to initialize an EEPROM. And in the absence of such a possibility, you need other means to accomplish your task. The current behavior provides you with this "plan b": If you set the rate and that doesn't work because no EEPROM is there, the driver fails. While doing it, it will release the device. This brings in the opportunity to access the touchscreen controller from userspace, e.g. with libusb, and write the EEPROM. After this, reboot, and be happy. Because now the device would act correctly on the "set rate" command and would be usable. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
