Sorry--neither helps me, but am more than willing to pay the €25 if you can fix my USB Peripheral problem. I consider my Just Ask Order still open if you can find solution.
(1) Clicked on Manual download for Wireless Desktop 280, and received Wireless Desktop 360 (mouse + Keyboard) which I suspect is close enough to the same, but no Software Drivers. Desktop 380 Manual refers to Installation CD for Driver Installation, which I don't have. Bottomline: Wireless Mouse problem is minor, and I can work thru.
(2) Clicked on 2x1 USB Peripherie-Switch and got the same Quick Installation Guide (with Installation CD Product # XXXXX) and User Manual that I already have. Software is properly installed on both my Desktop and my wife's Laptop. All works fine on my Desktop. Her Laptop simply does not recognize the USB device ("USB Geräte wurde nicht erkannt"), while at the same time displaying the Belkin W/L Peripheral Device Icon as Green, Yellow or Red and have the following error messages: "External Device Connected" or "External Device Busy". Bottomline: I can print from my Desktop and cannot from her Laptop with this device. So I'm at square one with individual printer cables from each of our computers alternatingly into the Color Laser Printer. I've lived with it this way for nearly a year, so can be patient for you to find the solution with this device. If no solution by Christmas, I'll give up and buy me something that works (wireless or not). Thanks...David Ralphs
