usb hub PCB review


Job Description

We had developed a PCB that includes a USB 2 hi-speed HUB based on the AU6254 chip, but the problem is that it does not work well on all computers. It seems to work nice on an older laptop with winXP, but on Win7 machines it is either undetected or the speed drops to <1mb/sec

So we are looking for a specialist in USB HUBs ( not just general PCBs ) to help us resolve this problem.
