https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=240339 --- Comment #15 from Vladimir Kondratyev <wulf@freebsd.org> --- (In reply to Greg V from comment #12) > I think I found the culprit, it's the length retrieval in get_input_report. I changed it to just trust the given length — touchscreen works, That sounds strange. Length retrieval breaks read pipelining, but I dont think it can result in such an errors. > err, actually, it's the thing where it writes the wInputRegister, which I don't think is supposed to happen. Write into wInputRegister can't result in any immediate errors as it is just a write into controller's FIFO. // and it's currently reading mouse reports.. I'll try to fix this. imt_set_input_mode() is responsible for converting mouse to touchpad -- You are receiving this mail because: You are the assignee for the bug.help
