On my laptop, which is a dell inspiron with windows xp, it works flawlessly and true plug & play both apc 40 & mpk49 work at same time so i know it is not a hardware issue. It has got to be a windows xp issueĪlso the windows xp computer is brand new out of the box ableton live 8 is the only program i have installed since takiing it out of the box. it picks them up as 'usb audio device' 1 or 2 or 3 but even setting them on separate ports still will only work if one of them is not plugged in. Right now only one of them will work at a time on that computer. My goal is to be able to use my apc 40 and mpk49 at the same time on my dell inspirion desktop running windows XP. They are emailing me a zip file with an executable that will uninstall the Logitech drivers. If you have previously installed a Logitech web camera, the device drivers conflict with the basic windows drivers used for the APC40. Update: I just got off the phone from AKAI. Have you tried to use the APC40 on a different USB cable? Please try this. Please disconnect all other USB devices other than a keyboard and mouse.ĭo you or have you ever had a Logitech or labtech camera? Please connect directly to the rear USB ports of your computer.ĭo not connect through front USB ports, keyboard USB ports, or monitor USB ports. Laptop or Desktop? What USB ports are you connecting too? Are you using a Hub? What have you tried in terms of your own troubleshooting, so far?
