Hello,

Right into it... from dmesg:

Aug 29 22:38:42 localhost /netbsd: umass0 at uhub4 port 7 configuration

head, 32 sec, 512 bytes/sect x 502912 sectors

Which would appear somewhat normal, except that this device has 1 GB of
flash so it should in theory have four times the sectors, right?

Beyond that, whenever anything is done with actually accessing the
device the command in question simply hangs, be it dd, fisk, or
mbrlabel.  Usually after a while I'll get multiple:

Aug 29 22:41:12 localhost /netbsd: umass0: BBB reset failed, TIMEOUT

Usually after a while the entire system will hang.  At times I've been
able to unplug it to get this:

Aug 29 22:42:00 localhost /netbsd: umass0: BBB reset failed, IOERROR
Aug 29 22:42:00 localhost /netbsd: umass0: BBB bulk-in clear stall

sd0 detached Aug 29 22:42:00 localhost /netbsd: scsibus0 detached
Aug 29 22:42:00 localhost /netbsd: umass0 detached

But again, usually I just get a system hang.

This device should work by most accounts - I've seen mention to it
working on FreeBSD and Linux, and I know it works on WinXP with no
separate drivers (standard USB mass storage).

For reference, uhub4 above is this:

...and (uname -a)...

NetBSD localhost 3.0 NetBSD 3.0 (GENERIC) #0: Mon Dec 19 01:04:02 UTC

i386


I've tried the device on another machine running NetBSD 3.0 with the
same results.  That machine had SiS-chipset USB/1.1 ports too.

My next thoughts are to try NetBSD 3.1 RC1.

Any ideas?  Help! :)
