Problem solved :-) All hangs I mentioned till now were coming from 2 identical enclosures I have, they report as: vendor=0x058f product=0x6390 devclass=0x00 devsubclass=0x00 release=0x0100 sernum="" intclass=0x08 intsubclass=0x06 2 other enclosures of different ID I have are OK. Should we extend devd or BSD USB code to issue a brief warning when devices match any in a lookup list of suspect rogues ? (Not the first flakey USB device I've encountered, Some Sony 2G sticks were bad, all 4, ( "vendor" "0x10d6"; "product" "0x1100"; "devclass" "0x00"; "devsubclass" "0x00"; "release" "0x0100"; ) PS Thanks for you power etc advice Warner :-) Further backround before conclusion above: { I moved same new 250G disc in same enclosure to another 7.1-RELEASE tower PC with & without USB hub, & with a current doubler cable (ie to suck up to a 2nd 0.5A from 2nd socket if disk wants) testblock -v /mnt/tmp/bla1 stopped writing at 5G. /var/log/messages & console: umass0: BBB reset failed, TIMEOUT umass0: BBB bulk-in clear stall failed, IOERROR umass0: BBB bulk-out clear stall failed, IOERROR umass0: BBB reset failed, TIMEOUT umass0: BBB bulk-out clear stall failed, IOERROR umass0: BBB reset failed, TIMEOUT g_vfs_done():da0a[WRITE(offset=65536, length=2048)]error = 5 g_vfs_done():da0a[WRITE(offset=6144000, length=16384)]error = 5 g_vfs_done():da0a[WRITE(offset=6160384, length=6144)]error = 5 g_vfs_done():da0a[WRITE(offset=198229819392, length=16384)]error = 5 .... I swapped the disc to a different USB to IDE converter, omitted case, disc does not get hot, but USB to IDE chip painfully hot (on good converter) + another power doubler cable, straight into PC, no hub, it wrote then read all remaining FS free space of 217 G succesfully. I swapped my other previously failing 120 G disc out of bad enclosure, into a known good enclosure, NO problems now on that either, have written 106 with no hang, & read verified 60 G as I type. } Cheers, Julian -- Julian Stacey: BSDUnixLinux C Prog Admin SysEng Consult Munich www.berklix.com Mail plain ASCII text.
