I received your HMC835LP6G Eval kit, which contains the HMC835 PLL eval board and a USB Interface board and a CD. I installed the software, but it does not recognize the USB board. I'm running Windows 7 64 bit. I also downloaded the current software on the HMC835 product page and it also does not recognize the USB. Do you have more up to date USB drivers, or any suggestions for how to resolve the issue? Thanks.
