Major Problem With Performance Mode using 2 CDJ900's on Win7

I'm not sure if this issue is a bug or glitch of some kind. I finally found out a solution to this issue. I want to clarify that when using 2 CDJ900's When runing. both my CDJ's into both powered and an unpowered usb2.0 Hubs. I also tried pluging both CDJ's directly into the 2 their own individual and separate usb2.0 ports on my computer. I have never had an issue with using a hub to connect my CDJ's. When using either Traktor or Searto in HID. The internal audio from the soundcards of both my CDJ900'S would some how get reversed, for example. The song that was loaded on to CDJ'1 would some how travel internally from CDJ1 through to CDJ 2 and eventually  though CDJ2 out through The RCA cable's on that unit into my mixer, even through CDJ2 wasn't the one being used to load,  cue or play etc. etc. And vice-versa. I have literally been up for close to 40hrs straight trying to figure this issue out. I literally ended up troubleshooting usb cable's, usb hubs, I eventually ended up re-wiring my entire studio. Yes, I installed the proper driver. Yes, my gear was routed properly and yes the software outputs were selected correctly in the software. I finally end up unpluging one of My CDJ's and actually pluging it in to one of USB 3.0 ports on my computer and this seemed to completely fix my issue. I would have tried this much earlier, however. I was under the impression from that these CDJ were not usb3.0 complainant. I almost certain I read this from a moderator on this forum arguing with someone in regards to lack of usb3.0 compliance on these earlier CDJ400's and 900's. I never had this issue using asio4all, ever since. I installed this newest Pioneer audio driver. I haven't been able to use asio4all or plug both my CDJs in to a usb2.0 port. I don't mean to jump to conclusion but it sure seams like Pioneer is intentionally trying to make things overly complicated. You know when, I first started Djing back in the late 90's House music and Djing was my way of escaping all the Bs and frustration of this world, Unfortunately Pioneer in the last couple years has become one of the largest manufacturers of Bs. right under politicians. Also, I want Pioneers CEO and Board members to hear me loud and clear. You really need to start treating all these people who have spent thousands of dollars on Pioneer products with a little more respect.
