Hello, In order to use my printer I just bought an USB to parallel connector. Whereas it works perfectly under Linux I am not able to print under FreeBSD. When I plug the USB connecter to my computer and set the ulpt debug level to 15, I can read: ugen2.4: <Prlific Technology Inc.> at usbus2 ulpt_probe: ulpt_probe: ulpt_attach: sc=0xfffffe0007f4fe00 ulpt0: <Prlific Technology Inc. IEEE-1284 Controller, class 0/0, rev 1.00/2.00, addr 4> on usbus2 ulpt_attach: setting alternate config number: 1 ulpt0: using bi-directional mode ulpt_status_callback: error=USB_ERR_STALLED The last message repeats indefinitely while the connecter is plugged in. When I try to read or write the /dev/ulpt0 it hangs.. About the usb to parallel cable it is an USB1 device: ugen2.4: <IEEE-1284 Controller Prlific Technology Inc.> at usbus2, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON (100mA) My FreeBSD version is 9.2: FreeBSD paris 9.2-RELEASE FreeBSD 9.2-RELEASE #0 r255898: Thu Sep 26 22:50:31 UTC 2013 root@bake.isc.freebsd.org:/usr/obj/usr/src/sys/GENERIC amd64 I found that in 2009 someone got the same problem and a patch was proposed but its URL is no more available: http://lists.freebsd.org/pipermail/freebsd-usb/2009-March/006531.html Please can you help me? Thank you in advance. Regards, Aurélienhelp
