Do you mean here? :
[ULPT_INTR_DT_RD] = { .type = UE_CONTROL,
...
   .timeout = 20000,        /* 20 second */

If yes, I tried but this does not change anything. I also tried to
change the ticks of the callout_reset in usb_watchdog().

But If I remove the transfer start in usb_watchdog() (so I never read
the status of the printer), it works well.

With cups and without the deframentation of the datas to write it seems
to work too (the same configuration as the top of this thread). Are you
sure this it required by my printer?

Not related but I noticed that usb_write() in usb_dev.c returns -1 if I
hit Ctrl-C when doing a "cat file > /dev/unlpt0". Because
usb_fifo_wait(f) returns -1 (should be EINTR?).

Thanks, regards.
