https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=244718 Bug ID: 244718 Summary: [patch] WMT driver usb framelength Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: usb Assignee: usb@FreeBSD.org Reporter: oskar.holmlund@ohdata.se Attachment #212306 text/plain mime type: Created attachment 212306 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=212306&action=edit Patch for wmt driver. Attached patch diff from r358834 CiVUE ACB-C27003 with controller EETI EXC80W32/P80H32 (newer eGalax multitouch). If usb frame length is set to 1024 bytes (WMT_BSIZE) the EETI controller will pack multiple touch events in the packet and the current code will only process the first touch event. (line 500: usbd_copy_out will only copy the first 64 bytes). As a result some important events are lost like releasing the finger from the touchscreen :) Just let the hardware report its maximum packet size. -- You are receiving this mail because: You are the assignee for the bug.home | help
