Do you guys know of any tool in Windows that will show up the kind of
information lsusb does?
Any tool that will provide information about what the device can do,
in a similar fashion to the lsusb info, but for Windows.
I would then send an email to Ricoh with this data, because I am
almost sure about the answer I would get if I send them the lsusb data
straight away...
Thanks in advance,
Albert.
