Cesar, there is only one copy of the output of "sudo lsusb -vvvv -d 0c45:8419", please can you run if for *both* the old and new firmware- revision devices, so that it's possible to compare and see if there is a way to tell them apart.
Please can you include the information from the manufacturer that confirms that they changed the firmware, without changing the USB ID. ** Summary changed: - Touchscreen not working + New revision of 0c45:8419 Microdia USB Touchscreen not working under 14.04 ** Changed in: evtest (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1519393 Title: New revision of 0c45:8419 Microdia USB Touchscreen not working under 14.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/evtest/+bug/1519393/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
