Actually, i took a "second round" attempt to make the thing work. A week or two after my postings there were commits to usb and CAM systems, after which the line in dmesg > umass0: A-DATA Technology Inc. USB Mass Storage Device, rev 2.00/0.01, addr 3 changed into > umass0: A-DATA Technology Inc. USB Mass Storage Device, rev 2.00/0.01, addr 3, 8070i > (ATAPI) over Bulk-Only See this "8070i (ATAPI) over Bulk-Only" part? I have a bad feeling that ATAPI can be a key word for my problems. (Before someone asks: yes, atapicam was also compiled into the kernel.) Anyway, i decided to try some quirks not only for scsi_da.c, but also for umass.c. To do so for my particular hardware, i had to add HW identifiers to src/sys/dev/usb/usbdevs and then to remake corresponding usbdevs* files using makefile in this directory. The change was: Index: /usr/src/sys/dev/usb/usbdevs =================================================================== RCS file: /home/ncvs/src/sys/dev/usb/usbdevs,v retrieving revision 188.8.131.52 diff -c -r184.108.40.206 usbdevs *** /usr/src/sys/dev/usb/usbdevs 2 Sep 2003 14:35:17 -0000 220.127.116.11 --- /usr/src/sys/dev/usb/usbdevs 11 Sep 2003 13:50:54 -0000 *************** *** 1002,1007 **** --- 1002,1010 ---- product PROLIFIC PL2303 0x2303 PL2303 Serial adapter (ATEN/IOGEAR UC232A) product PROLIFIC PL2305 0x2305 Parallel printer adapter product PROLIFIC ATAPI4 0x2307 ATAPI-4 Bridge Controller + product PROLIFIC PL2515 0x2515 PL2515 Embedded hub + product PROLIFIC PL2517 0x2517 PL2517 Mass Storage Device + /* Putercom products */ product PUTERCOM UPA100 0x047e USB-1284 BRIDGE Values initially were taken from the output of usbd -vv Then i put some dummy quirk into umass.c - it only does a printf() ("PL2517 quirk was applied"). It worked, but something strange (to me) happened: message was printed three times in a row! Well, possibly this is not strange - i'm not a C person to read devices probing code... Then i tried some quirks mentioned here and there, but to no avail... and here my "research" stopped (lack of time). So, until now the bottom line is: If your device is made with PL-2515 chip - you'll probably will have the same problems. Actually, i even opened mine, and it really contains this Prolific chip. Info on the chip: http://www.prolific.com.tw/fr_pl2515.htm Some technical info and Windows stuff is aviliable via http://tech.prolific.com.tw Sorry, this is all i have for now... Device is still availiable, so in a week or two i'll be able to put my hands on it again. Hints and suggestions are welcome...
