----------------------------------------------------------------------
When acting as a USB mass storage controller ("USB Connection" mode),
the PSP accepts a few vendor-specific SCSI command blocks. This
program sends these commands via the Linux generic SCSI interface and
displays the results.
To build, just run
$ make
To run, pass it the device node of your connected PSP. Note that
it must be run as root, because Linux blocks unknown SCSI commands
for non-root users:
# ./pspi /dev/sda
The command to format the memory stick is commented out in the source,
but it does work. The remaining commands should be non-destructive.
This is the output for a PSP with firmware 2.82:
