Hi Hans,
I just figured-out the ulpt(4) driver in my Epson printer while comparing
with my Xprinter printer's USB device info. My Epson printer is providing
vendor specific values of 255 in the bInterfaceClass and bInterfaceSubClass
respectively.
bInterfaceClass = 0x00ff <Vendor specific>
bInterfaceSubClass = 0x00ff
It should be a value of 7 for bInterfaceClass and a value of 1 in
bInterfaceSubClass.
bInterfaceClass = 0x0007 <Printer device>
bInterfaceSubClass = 0x0001
So, the ulpt_attach() routine below will break upon validation for
mismatched values in UICLASS_PRINTER and UISUBCLASS_PRINTER.
} else {
alt_index++;
if ((id->bInterfaceClass ==
UICLASS_PRINTER) &&
(id->bInterfaceSubClass ==
UISUBCLASS_PRINTER) &&
(id->bInterfaceProtocol ==
UIPROTO_PRINTER_BI)) {
goto found;
}
}
What I did is temporarily replace these values in the USB definition. In
this case, how should the project handle this non-compliance USB devices?
Though I will raise this to Epson if they could provide an updated firmware.

I can print now with ulpt(4) driver but need further testing for any issues.
