https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D253232 --- Comment #5 from Hans Petter Selasky <hselasky@FreeBSD.org> --- Thanks for testing. It appears that your printer devices has not been through enough low-level = USB testing. Maybe you could write an e-mail to the manufacturer of the USB ulpt device saying that the USB request clear endpoint halt is broken and causes the de= vice to halt. The main problem here is that if you abort a job, the next job may need a clear-stall message to recover the so-called data-toggle. Else you may loose the contents of one USB packet on the wire :-( If you never abort jobs, than there is no problem. Should we perhaps implement a quirk you can set, that prevents clear-stall = from happening? I really don't like to fix FreeBSD because USB manufacturers are not follow= ing specs .... What do you think? --HPS --=20 You are receiving this mail because: You are the assignee for the bug.=
