Hello,
I have a Bontempi PM747 keyboard with an USB midi interface. When I connect it to the computer, the device manager shows a yellow triangle and a code 10 error.
I have executed all steps Windows advises me to do, including downloading and installing the latest
driver from the Bontempi site. This
driver installation (.exe file) reports a succesful installation, but it does not help, Windows does not recognize the keyboard and it can not be used in my music software.
Any suggestions?
