Well, what do you know, a quick mount_msdos /dev/da0s1 worked just fine
;). Something to add to the hardware compatibility list I guess. Here's
the dmesg entry:
umass0: In-System Design USB Storage Adapter, rev 2.00/11.01, addr 2
da0 at umass-sim0 bus 0 target 0 lun 0
da0: <IC35L120 AVV207-0 V24O> Fixed Direct Access SCSI-0 device
da0: 650KB/s transfers
da0: 117800MB (241254720 512 byte sectors: 64H 32S/T 52264C)
I did get the below message, but it does not seem to goof up anything.
(da0:umass-sim0:0:0:0): READ(6)/WRITE(6) not supported, increasing
minimum_cmd_size to 10.
My laptop only has USB 1.1 anyway (it's an old Latitude L400 -- don't
think it has 2.0 anyway). 650KB/s is fine. I'm just using it to back up
my *cough*VERY LEGAL*cough* mp3s ;)
Thanks for setting my head straight about this. I think this should be
listed on the web page. The reason I asked in the first place is because
there are no mailing list articles about this (that Google could find
with about 31899821498 different queries, anyway ;) and the webpage
gives me the idea that it doesn't support larger devices.
