i have the Logitech MX Revolution (the original from 2006) and i am missing the stupid USB receiver. the receiver part number is 831735-1000. if anyone has one of these in their electronic component junk drawers and wants to get rid of it, please let me know.
i have been in a week-long conversation with a Logitech support representative - they were amazed this mouse was still working 15 years later and after suggesting i check amazon marketplace and ebay for a compatible receiver (there were none, or they were bundled with the mouse for an excessive price), they said they would keep an eye on their internal ‘spare parts bin’ and let me know if one showed up there.
