This patch gets the Kyocera FS-820 working with cups 1.2 via usb again. It adds the printer to the list of "quirky" printers. The printer seems not answer to ID requests some seconds after plugging in. Patch is based on linux-2.6.19.1. Background: As far as I could see (strace, usbmon), the Kyocera FS-820 answers to ID requests only a few seconds after plugging it in. This applies to detecting it with cups and is also true for the printing itself, which is initiated with an ID request. Since I have little usb knowledge, maybe someone can interpret the data, especially the fist bulk transfer - why request 8192 bytes? This is the second version of the patch. usbmon output of printing an email without patch: tail -F /tmp/printlog.txt c636e140 3374734463 S Bi:002:02 -115 8192 < c9d43b40 3374734494 S Ci:002:00 s a1 00 0000 0000 03ff 1023 < c9d43b40 3379732301 C Ci:002:00 -104 0 c636e140 3379733294 C Bi:002:02 -2 0 [...repeating...] with patch: tail -F /tmp/printlog.txt d9cb82c0 3729790131 S Ci:002:00 s a1 00 0000 0000 03ff 1023 < d9cb82c0 3729791725 C Ci:002:00 0 91 = 005b4944 3a46532d 3832303b 4d46473a 4b796f63 6572613b 434d443a 50434c58 df956320 3732493190 S Bo:002:01 -115 1347 = 1b252d31 32333435 5840504a 4c0a4050 4a4c2053 4554204d 414e5541 4c464545 [...more data...] Signed-off-by: Martin Williges <kernel@zut.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de> |
