I have 2 different usb umass devices with multiple 'drives' in them --
they both use different luns for this - for whatever reason (perhaps the
get-max-luns call fails?) only lun 0 is ever scanned.
To get them to work all I need do is:
camcontrol rescan X:Y:1
and they will be found. the lowest devices is usually 'automatically'
found as X:Y:0 and so I just need to manually scan the other luns and all
is good.
(JamP3 mp3 player has luns 0 and 1, and my Neodio 6-in-1 flash reader - 4
slots CF/Microdrive SD/MMC Memorystick and smartmedia -
The appropriate quirk for the 6 in 1 device in scsi_da.c is:
{
{T_DIRECT, SIP_MEDIA_REMOVABLE, "Generic", "USB Storage-*","*"},
/*quirks*/ DA_Q_NO_6_BYTE|DA_Q_NO_SYNC_CACHE
},
and the quirk for the JamP3 is unvailable on a machine that is down right
now... It looks very similar :).
Hope this helps.
Just remember to camcontrol rescan the right lun and you should have no
problems.
