 Subject : Помогите разобраться с USB принтером ...
 -------------------------------------------------------------------------------- 
 

 Привет Всем!
 
 Возможно  кто-нибудь  поможет  разобраться  с  USB  принтером  HewLett
 Packard HP LaserJet 1200, буду весьма благодарен. Суть проблемы в том,
 что  он определяется драйвером USB как ugen0 девайс, а не ulpt0 как по
 идее  должен.  В  архивах freebsd-questions@freebsd.org нашел ответ на
 подобный  вопрос.  Как  я понял из ответа, варианта два - либо драйвер
 ulpt  кривой,  либо  принтер  не  следует стандарту USB для принтеров.
 Поскольку  в  С  я  никак не разбираюсь, то последовать совету изучить
 исходник ulpt.c и выяснить истину не могу :(.

 Make absolutely sure you're running a kernel with the ulpt code
 compiled into it.
 
 If that is the case, then you're probably going to have to start
 working on the driver source in /usr/src/sys/dev/usb/ulpt.c In
 particular, USB_MATCH(ulpt) walks through the description of the USB
 device making sure it's a printer that speaks one of the protocols
 that the ulpt driver supports. Check to see why that's failing, and if
 how it will do on any tests that may not be making. You can then try
 assuming that the printer's USB support is broken, and tweak the
 driver so the printer passes the test and see how things go.
 
 On the other hand, you may have a printer that connects via USB, but
 doesn't follow the USB standards for printers, or doesn't support any
 of the protocols that ulpt needs. In which case, things are going to
 be noticably harder.
