This works both now with my Epson TM-U220B and Xprinter printers. It can detect either or both in 14.0-CURRENT. So far I haven't encountered any strange behavior while printing using this ulpt(4) driver. freebsd@generic:~ % diff -Nur /usr/src/sys/dev/usb/serial/ulpt.c.orig /usr/src/sys/dev/usb/serial/ulpt.c --- /usr/src/sys/dev/usb/serial/ulpt.c.orig 2022-03-21 19:44:29.178010000 +0800 +++ /usr/src/sys/dev/usb/serial/ulpt.c 2022-03-31 16:57:53.317952000 +0800 @@ -495,6 +495,11 @@ USB_IFACE_SUBCLASS(UISUBCLASS_PRINTER), USB_IFACE_PROTOCOL(UIPROTO_PRINTER_BI)}, + /* Bi-directional USB vendor specific */ + {USB_IFACE_CLASS(UICLASS_VENDOR), + USB_IFACE_SUBCLASS(UISUBCLASS_VENDOR), + USB_IFACE_PROTOCOL(UIPROTO_PRINTER_BI)}, + /* 1284 USB printer */ {USB_IFACE_CLASS(UICLASS_PRINTER), USB_IFACE_SUBCLASS(UISUBCLASS_PRINTER), @@ -555,9 +560,11 @@ break; } else { alt_index++; - if ((id->bInterfaceClass == UICLASS_PRINTER) && - (id->bInterfaceSubClass == UISUBCLASS_PRINTER) && - (id->bInterfaceProtocol == UIPROTO_PRINTER_BI)) { + if ((id->bInterfaceClass == UICLASS_PRINTER || + id->bInterfaceClass == UICLASS_VENDOR) && + (id->bInterfaceSubClass == UISUBCLASS_PRINTER || + id->bInterfaceClass == UISUBCLASS_VENDOR) && + (id->bInterfaceProtocol == UIPROTO_PRINTER_BI)) { goto found; } } In the /usr/src/sys/dev/usb/usbdevs, I think there's a need to include the undefined TM-U220B. freebsd@generic:~ % diff -Nur /usr/src/sys/dev/usb/usbdevs.orig /usr/src/sys/dev/usb/usbdevs --- /usr/src/sys/dev/usb/usbdevs.orig 2022-03-21 19:42:20.999397000 +0800 +++ /usr/src/sys/dev/usb/usbdevs 2022-04-01 01:21:31.361567000 +0800 @@ -1941,6 +1941,7 @@ product EPSON 2480 0x0121 Perfection 2480 scanner product EPSON 3590 0x0122 Perfection 3590 scanner product EPSON 4990 0x012a Perfection 4990 Photo scanner +product EPSON TMU220B 0x0202 TM-U220B product EPSON CRESSI_EDY 0x0521 Cressi Edy diving computer product EPSON N2ITION3 0x0522 Zeagle N2iTion3 diving computer product EPSON STYLUS_875DC 0x0601 Stylus Photo 875DC Card Reader Thanks, Archimedes
