Glenn9999 Posted November 13, 2018 Share Posted November 13, 2018 I ended up acquiring a RJ45 to USB adapter (kind of port that a flash drive could go into). As stated in the title, I tried to figure out what you would do with it, but didn't have much success. I found a lot of details about wiring cables in such a way and places to buy adapters much like the one I have off of Google, but didn't find any explanation of why you would want such a thing. Any explanations would be welcome. Link to comment Share on other sites More sharing options...
Tripredacus Posted November 13, 2018 Share Posted November 13, 2018 A picture would be nice, even if you can find a stock photo of what you have. From your existing post "kind of port that a flash drive could go into" makes me think that one end is a USB Type A receptacle. However, the other side, the RJ45, you don't specify if it is a port or a connector. I'm sure there are various uses for such a device. A quick looksee on Amazon (ASIN: B005DDI51U) for example, says this particular adapter is to connect a USB ADSL modem to a router. If the thing you have is not the same as the thing from Amazon, then I used this phrase in google search: RJ-45 USB Type A adapter Link to comment Share on other sites More sharing options...

What you posted help me nail down what it is a bit more. It's a Female USB A to Male RJ45 adapter. I don't know what brand it is specifically as it's unmarked, but this one on Amazon is a decent representation of what it is. Link to comment Share on other sites More sharing options...
Tripredacus Posted November 13, 2018 Share Posted November 13, 2018 I have accumulated all sorts of weird adapters over the years as well. I rarely try to figure them out, just put them in a bin of mystery connectors. Link to comment Share on other sites More sharing options...

With TWO of them, you may do something (actually rather pointless, still ...) : https://www.delock.com/produkt/65234/pdf.html?sprache=en CAT5/CAT6 cable is actually very good to carry non-etherrnet signals too, and in some cases you can exceed USB length specifications (around 4.5 mt length without booster/repeater), very, very old example: https://web.archive.org/web/20080422023938/https://girasoli.org/?p=58 There are actually some (very few AFAIK) devices that (for *some reasons*) have an USB port in the form of an RJ45 port (and no, it is VERY unlikely that you have one of them): https://www.schneider-electric.com/en/product/TCSMCNAM3M002P/connection-cable-usb-rj45---for-connection-between-pc-and-drive/ On 11/13/2018 at 12:55 PM, Tripredacus said: I have accumulated all sorts of weird adapters over the years as well.

Mcinwwl Posted November 19, 2018 Share Posted November 19, 2018 I'd start from asking, why have you bought such a device, without knowing what it can be used for? A hobbyist, collector of mysterious converters and adapters, or you just felt sad for 'em cables laying around useless and lonely? Link to comment Share on other sites More sharing options...

Well, JFYI, I have actually two of those adapters + a small mouse and a number of (extensible) cables, a mini-hub and other converters all in a nice zippered bag more or less *like* these ones: https://www.diytrade.com/china/pd/3691995/usb_travel_kit_usb_travel_bag_usb_bag_usb_kit.html https://www.bidorbuy.co.za/item/365382159/USB_and_Mouse_Toolkit.html I call it (connection) "preparedness" https://quoteinvestigator.com/2018/07/08/plan/ jaclaz Link to comment Share on other sites More sharing options...
Mcinwwl Posted November 19, 2018 Share Posted November 19, 2018 Thanks for giving an answer proposal, but we both know I wasn't asking you The difference is that you posted some uses of such adapters, while Original Poster didn't... well, actually he asked for them, which makes your cases differ at a crucial point Link to comment Share on other sites More sharing options...

Basically a lot of stuff - I didn't really set out to obtain the specific part in question. Link to comment Share on other sites More sharing options...
