I'm trying to connect my 2 cdj-400's via usb to my desktop. I've updated firmwares to 1.33 - fully updated windows and installed the latest 1.5 drivers. The cdj's when plugged in show up as 'usb composite device' with driver errors on device manager / devices. I've tried reinstalling all drivers, usb drivers etc. to and virus scans / malware scans and then a full format. - I installed them no problem on my laptop which has the same windows on same updates, using the same usb wires so it rules out that. they show up fine as cdj 400's both of them.
I've literally spent about 15 hours trying to sort this out and it's driving me crazy - a couple of more things I've tried / tested.
Motherboard bios is up to date, usb cables directly in motherboard, cdjs on pc mode and off pc mode. (Oh the pioneer software version display utility shows them there as cdj400's 1.33 firmware ) . please help I'd really like to get this sorted so I can use them and I'm totally lost now.
One note - on the cdj 400 support / driver page ( https://www.pioneerdj.com/en-gb/product/player/archive/cdj-400/black/support/ ) there is a 'software update' 1.0.4 - which has been updated 5th sept? it doesn't link to anything because it's archived?
Thanks in advance
