"Determining connected device(s) failed" error message
the error message "Determining connected device(s) failed" message appears
during driver installation under Windows, it normally indicates that the ESI USB
product you are trying to install the driver for has not been properly connected
to the USB port when the installer requests it, or Windows has not detected the
device yet. For example, under Windows XP the message looks something like this:
order to avoid this issue, please note these:
- make sure you have downloaded
the correct driver for your ESI product and not for a different product
sure that you wait at least a couple of seconds before clicking Next on
the previous installer dialog to give your computer and Windows enough time to
detect the USB device
- make sure the USB cable has been connected properly
to the computer
- if a USB hub is used, make sure it is connected properly,
powered (if required) and working
Most commonly this error message
appears with the RoMI/O
and MIDI Mate (Rev.
A) device drivers when there is an attempt to install the for a different hardware
revision of RoMI/O and/or MIDIMATE (i.e. a RoMI/O
II or MIDIMATE II).
If you are using a RoMI/O or MIDIMATE MIDI interface, please double check this:
cannot install the RoMI/O driver with RoMI/O II (RoMI/O II works without any driver)
cannot install the MIDI Mate Rev. A driver for MIDIMATE Rev. B (MIDIMATE Rev.
B has a separate driver download)
- you cannot install the MIDI Mate Rev.
A driver for MIDIMATE II (MIDIMATE II works without any driver)
get more information, please check this Knowledge Base article
about RoMI/O models and variants and this Knowledge Base
article about MIDIMATE models and variants.
If you are 100% sure that
the driver you are trying to install is correct for the device you have and the
message still constantly appears, there might be a hardware problem on your system
or a hardware defect (cable, connection, actaul fault of the ESI product, USB
port on your computer, etc.). So please double check everything above first, possibly
try it on another computer and if you cannot resolve it with that information,
contact our technical support
with as much detail about the issue as possible. Please include the serial number
of the ESI product if known / available.
