** Description changed: Filing here per request at: - http://irclogs.ubuntu.com/2015/11/24/%23ubuntu-devel.html#t14:35 + http://irclogs.ubuntu.com/2015/11/24/%23ubuntu-devel.html#t14:35 I have approximately fifty USB touch panels. These are from two different batches, but all report the same USB ID 0c45:8419. The manufacturer told me they had changed the firmware without changing the USB ID/version because they did not consider the change important. Both batches work correctly on Ubuntu 10.04, but only one batch works on 14.04. As such, this is a regression. After plugging in, both batches appear equivalently as: - /dev/input/eventNN + /dev/input/eventNN and for both 'evtest' reports: - Input device ID: bus 0x3 vendor 0xc45 product 0x8419 version 0x100 - Input device name: "SONiX USB Device" - … + Input device ID: bus 0x3 vendor 0xc45 product 0x8419 version 0x100 + Input device name: "SONiX USB Device" + … + Presumably something is occuring that causes a version version of + 'libev' to handle one batch differently. Attached is the output of + running: - Presumably something is occuring that causes a version version of 'libev' to handle one batch differently. + $ sudo lsusb -vvvv -c -d 0c45:8419 > ….txt + + for one device from each of the two batches. ** Description changed: Filing here per request at: http://irclogs.ubuntu.com/2015/11/24/%23ubuntu-devel.html#t14:35 I have approximately fifty USB touch panels.
