Hi Nicos,
I've just tried a noname Mostech 9901 Parallel+2 serial card with the
parallel_serial driver and the parallel doesn't seem happy (not tried
the serial yet). It's connected to an ancient Brother HL-1030
(which to be fair is fussy about which USB-parallel leads it works with).
Using the parallel_serial's autodetect in 3.7.0rc5 it finds it as:
Dec 7 18:05:17 thedr kernel: [ 8.092836] lp: driver loaded but no devices
found
Dec 7 18:05:17 thedr kernel: [ 8.637003] parport0: PC-style at 0xe010
(0xe000), irq 18, using FIFO [PCSPP,TRISTATE,COMPAT,ECP]
Dec 7 18:05:17 thedr kernel: [ 8.713196] ppdev: user-space parallel port
driver
Dec 7 18:05:17 thedr kernel: [ 8.749639] lp0: using parport0
(interrupt-driven).
Printing first caused a complete hang, the second time it got further
managing to print about 1/3 of a page before spewing blank pages
rapidly, with the log message:
Dec 7 18:13:15 thedr kernel: [ 491.016639] lp0: ECP mode
Dec 7 18:13:29 thedr kernel: [ 504.464473] lp0: ECP mode
Dec 7 18:13:39 thedr kernel: [ 515.065742] FIFO write timed out
Dec 7 18:13:49 thedr kernel: [ 525.138859] FIFO write timed out
Instead I passed parport_pc the io and irq from the lspci and it's working,
although in polling mode:
Dec 7 18:27:14 thedr kernel: [ 15.024104] parport0: PC-style at 0xe010, irq
18 [PCSPP,TRISTATE,EPP]
Dec 7 18:27:14 thedr kernel: [ 15.024110] parport0: irq 18 in use, resorting
to polled operation
Dec 7 18:27:14 thedr kernel: [ 15.025954] parport0: Printer, Brother HL-1030
series
Dec 7 18:27:14 thedr kernel: [ 15.026157] lp0: using parport0 (polling).
(This is with an Ubuntu Quantal user space - I'm assuming the inuse is
because parport_serial also got loaded).
Here is the lspci -v output:
