Hi Simon, In case of mobile devices with different vendorID/productID, you try to use USB_DEVICE_INFO macro to identify your mobile devices. Since the devices are with differences vendor ID and product ID.
With these changes your driver recognizes all of your mobile devices. I hope you understand this.

Create a new usb-serial drivr for this device, which will allow you to increase the data rates and handle more devices properly. The generic driver is not ment for "real" workloads like you are trying to use it for. thanks, greg k-h _______________________________________________ [email protected] To unsubscribe, use the last form field at: https://lists.sourceforge.net/lists/listinfo/linux-usb-users _______________________________________________ [email protected] To unsubscribe, use the last form field at: https://lists.sourceforge.net/lists/listinfo/linux-usb-users
