I too am struggling to make my iogear KVM switch (model GCS632U) work with my wireless keyboard/mouse with unifying receiver. The same KVM used to work fine with my old wireless desktop wave keyboard/mouse with its single USB receiver (that was much larger than the half thumbnail-sized unifying receiver, more like a thumb drive)... but then I installed a wireless printer and I started getting all these weird keyboard delay issues and keys not working or ending up with a string of eeeeeeees when I was just trying to type the word "the." So I upgraded to the latest Logitech keyboard - the K350 - with it's Unifying Receiver (UR) and upgraded to a mouse that also used the UR. Suddenly, my brand new kick-ass VAIO VPCF115FM/B laptop with Windows 7 wouldn't recognize the new keyboard/mouse, but the other connected computer an older HP with XP worked just fine and I had full functionality of the keyboard and mouse and could even operate the switch with the Unifying Receiver plugged into the the Keyboard port on the GCS632U KVM, but when I switched to the laptop, nothing happened and all my troubleshooting to make it work including downloading the latest drivers for use with a Windows 7 64-bit machine failed. So Logitech support said plug it directly into the USB slot on your laptop, and of course, it worked and the keyboard delay and miscue issues that occured with the old Wireless Desktop Wave setup were fixed, so my perceived interference issues with the HP wireless printer were eradicated... but the damn KVM switch still doesn't work. Iogear's tech support on the issue was abysmal. The agent said they don't support wireless setups, only wired keyboard/mice, and I said but it works with my XP machine! Then, I had to stop the Peggy-like android from executing yet another algorithm of pre-determined responses to ask "Do you make a KVM that is Windows 7-certified... I'm still thinking Windows 7 may be the barrier. She said I could try the Iogear GCS1732 KVM, but said the company still cannot guarantee compatibility with any wireless keyboard/mouse. Does anybody out there have a success story with the GCS1732 KVM paired with Logitech's Unifying Reciever mice and keyboards? If not, is there a Trendnet or some other KVM that is working in someone's Windows 7 environment?
