I have an ego-t passthough. I'm assuming the ego is the same connection. I just uses a standard mini USB cable. Same thing most camera's use. (not mico usb, most smart phones use micro, and not standard usb, most printers use standard) The technical specs are 'USB A (Male) to B Mini 5 Pin (Male)' Go to eBay and do a search on that. Very common and very cheep. You can get them for like 50 cents, with free shipping from china, but takes a couple weeks. You can get them from a USA seller for like $1-2 each and get alot faster. Or you can go to your local retailer and get one for like $10-$15.. lol... way more expensive, but you get it right away and don't have to wait a few days. And FYI, don't let someone sell you on a 'super gold plated... turbo charged, high quality, will help you save the planet', type cable, lol.. They are all the same... haha Just make sure its long enough to go from your computer to your mouth. 6ft should be fine..
