list, I have been battling getting my HP dvd420e usb drive to work without much luck partly since I haven't been able to commit any resonable time for the task. Finally having some time on my hands I rolled up my sleaves, determined to tackle this bastard. My problem was that on attatching the drive, I got the message: -------------------- Dec 12 20:32:29 sr-160 kernel: umass0: HEWLETT PACKARD S1, rev 2.00/0.01, addr 2 Dec 12 20:32:29 sr-160 kernel: umass0: SCSI over Bulk-Only; quirks = 0x0000 Dec 12 20:32:29 sr-160 kernel: umass0: Get Max Lun not supported (STALLED) Dec 12 20:32:29 sr-160 kernel: umass0:0:0:-1: Attached to scbus0 Dec 12 20:32:29 sr-160 kernel: umass0: Phase Error, residue = 0 Dec 12 20:32:33 sr-160 last message repeated 4 times -------------------- According to <http://lists.freebsd.org/pipermail/freebsd-questions/2003-September/020826.html>; the "Get Max Lun" seems to be the purpotrator. Following advice from <http://www.root.org/~nate/freebsd/quirks.html>; I added the lines: -------------------- { USB_VENDOR_HP, PID_WILDCARD, RID_WILDCARD, UMASS_PROTO_ATAPI | UMASS_PROTO_CBI_I, NO_GETMAXLUN }, { USB_VENDOR_HP2, PID_WILDCARD, RID_WILDCARD, UMASS_PROTO_ATAPI | UMASS_PROTO_CBI_I, NO_GETMAXLUN }, -------------------- to /usr/src/sys/dev/usb/umass.c (vendor names taken from /usr/obj/usr/src/sys/PALANTIR/usbdevs.h) and made world. This, sadly, did not resolve the problem. On attach the machine now reboots and if booted with the drive attatched, I get: -------------------- Fatal trap 18: integer divide fault while in kenel mode instruction pointer = 0x8:0xc0666b73 stack pointer = 0x10:0xcc7017dc frame pointer = 0x10:0xcc701864 code segment = base 0x0, limit 0xffffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 36 (swi3: cambis) [thread 100040] Stopped at __qdivrem+0x3b: div( %ecx,%eax -------------------- The same message appeared when I tried rebooting later, again with the drive attached. Apparently, something more than just the NO_GETMAXLUN quirk to get this guy to work. Any suggestions? Martin Swift Ps. After modifying a source file, what exactly is needed to remake the neccisary parts? Would in my instance cd sys/modules/usb/ && make && make install have done the trick? -- Góð ráð og dýr: <http://www.webfoot.com/advice/email.top.html>; <http://www.rfc-editor.org/rfc/rfc1855.txt>; <http://catb.org/~esr/html-hell.html>;help
