hey hey, anyone else willing to take a stab at this? fwiw, i am fairly certain that the problem resides somewhere between the keyboard and the chair, however i would appreciate confirmation (i think :) before i do something silly like submitting a pr or sending this off to another list. (note that i had two very right suggestions to add the umass device, however that didn't solve the problem, because i already had it compiled into my kernel. i simply forgot to include it in this message. this has been corrected below...) apologies for the lengthy message. really wanted to provide as much useful info as i could. thanks to all who suffer through the verbiage, yet resolutely give it a go. -------------------- hello all, for many moons now, i'll occasionally dedicate a dark day to getting my USB Zip drive to work. i've been through the handbook, faq, relevant man pages, mailing lists and across the colossal googlesphere collecting bits and pieces, none of which seem to get me the desired result. i'm obviously missing something. i'm writing with the hope that, what i have managed to overlook will be so obvious and straighforward, some kind reader will take 2 seconds to point it out, so that i may zip off on my merry way. ### uname -a FreeBSD 4.10-RELEASE-p1 i386 ### relevant lines from kernel device vpo device scbus device da device umass device uhci # uhci related entries show up in dmesg device usb device ugen i have also tried with the ohci device added, but it never generates any dmesg entries. from what i gather, uhci and ohci have an 'either - or' kind of relationship. i'm supposing that uhci is the right device for my system. now, when i boot with the zip device plugged in (whether or not there is a disk loaded), the system will hang until i unplug the usb cable. ### dmesg <snip> atapci0: <Intel PIIX4 ATA33 controller> port 0x1050-0x105f at device 7.1 on pci0 ata0: at 0x1f0 irq 14 on atapci0 ata1: at 0x170 irq 15 on atapci0 uhci0: <Intel 82371AB/EB (PIIX4) USB controller> port 0x1060-0x107f irq 5 at device 7.2 on pci0 usb0: <Intel 82371AB/EB (PIIX4) USB controller> on uhci0 usb0: USB revision 1.0 uhub0: Intel UHCI root hub, class 9/0, rev 1.00/1.00, addr 1 uhub0: 2 ports with 2 removable, self powered ##-- hangs here for about 30 seconds, then chugs on happily --## chip0: <Intel 82371AB Power management controller> port 0x1040-0x104f at device 7.3 on pci0 pcm0: <ESS Technology Maestro-2E> port 0x1400-0x14ff irq 5 at device 8.0 on pci0 <snip> pccard: card inserted, slot 1 ad0: 17301MB <TOSHIBA MK1814GAV> [35152/16/63] at ata0-master UDMA33 acd0: CDROM <TOSHIBA CD-ROM XM-7002B> at ata1-master UDMA33 ##-- hangs here *until* i pull the usb plug. after i do, i get the following error messages but the boot finishes nicely. --## umass0: BBB reset failed, IOERROR umass0: BBB reset failed, STALLED umass0: BBB bulk-in clear stall failed, STALLED umass0: BBB bulk-out clear stall failed, STALLED umass0: BBB reset failed, STALLED umass0: BBB bulk-in clear stall failed, STALLED umass0: BBB bulk-out clear stall failed, STALLED umass0: BBB reset failed, STALLED umass0: BBB bulk-in clear stall failed, STALLED umass0: BBB bulk-out clear stall failed, STALLED Mounting root from ufs:/dev/ad0s2a umass0: at uhub0 port 1 (addr 2) disconnected umass0: detached <snip> ### /var/log/messages Jul 4 21:47:04 /kernel: umass0: Iomega USB Zip 100, rev 1.00/1.00, addr 2 Jul 4 21:47:04 /kernel: umass0: Get Max Lun not supported (STALLED) Jul 4 21:48:09 /kernel: umass0: BBB reset failed, IOERROR ### after booting, i plug the usb cable back in and usbdevs -v: Controller /dev/usb0: addr 1: full speed, self powered, config 1, UHCI root hub(0x0000), Intel(0x0000), rev 1.00 port 1 addr 2: full speed, self powered, config 1, Zip 100(0x0001), Iomega(0x059b), rev 1.00 port 2 powered ### ps auxw | grep -i usb root 99 0.0 0.2 940 604 ??

DL 5:42PM 0:00.00 (usb0) looks good (i think). ### mounting i'm not sure that i 'get' which device the zip maps to nor how to determine this. i have tried about 40 different combinations of mount (mostly gleaned from my research), but i have yet to hit upon the right command. # mount -t msdos /dev/da* /mnt # * = practically every single one msdos: /dev/da0s4: Device not configured ...with the same results for /dev/sa* devices. of the many combinations tried, /dev/usb0 has provided the most promising error message (i think). # mount -t msdos /dev/usb0 /mnt msdos: /dev/usb0: Block device required ### final notes 1) not the drive - it works on several other non-*nix systems 2) not the usb port itself - boot to another OS and it works. 2) not the zip disks - have tried different disks all known to be good if there is any further testing i can do or details i can provide, please let me know. many thanks, epi
