I requested for a support at Logitech technical support website for my recently bought Trackman Marble mouse from Logitech. I just get back the auto response as shown below and no further feedback from Logitech until today. Logitech Resellers in Thailand also are hopeless and refused to provide any assitance for my problem by saying that they do not have enough knowledge about the product. I am stuck with it as I could not get the replacement or help from Logitech. Never ever buy anything from Logitech in the future.

I am using the USB to PS2 adapter to connect to my KVM swtch. Since the Clicks on my old mouse are not functioning properly because of its old age and I bought the new logitech marbel one same model (Grey color) as I have from a shop last Saturday. I plug it into my KVM switch and tested. To my surprise it does not work. I plug it in directly to a USB port of a PC or a PS2 port of a PC using an adaptor I noticed it works fine. I could not figure it out why it happens. When I go back to the shop they said the mouse is not damaged and refuse to refund the money. I bought it to use with my KVM switch and now it is not working. What should I do. Please kindly advice. Auto-Response 03/10/2010 11:24 PM This is an autoresponse message.
