erikkugel | yup. apperently (and maybe you are right and I'm making no sense) one can run anything over CAT5. I know I have an APC BackUPS uninterrupted power-supply which connects to the UPS with an Ethernet jack and to the workstation with a USB jack for monitoring. I'm looking for that page right now. | 00:00 |

erikkugel | And here's the link for USB over CAT5: http://www.instructables.com/id/Usb-Dongles-for-USB-over-CAT5-connection/ | 00:01 |
wpwrak | oh, you can run anything over CAT5. but you still have to connect like to like. USB to USB or Ether to Ether :) | 00:01 |
wpwrak | yes, that's still USB to USB. just with a CAT5 cable in the middle. is that what you're looking for ? | 00:02 |
wpwrak | before, you wrote about a USB port to an Ethernet port. that requires a relatively complex conversion circuit (i.e., a USB Ethernet dongle) and driver support | 00:03 |
erikkugel | I naively assumed that the adapters for Ethernet to USB ( http://www.nextag.com/usb-to-rj45-adapter/stores-html ) were "dumb" and I could just make one by wiring the cables myself. I think you are saying that this wont work? | 00:03 |
wpwrak | well, that's USB host -> Ether. Ether -> USB device is even harder. | 00:03 |
wpwrak | they're not dumb ;-) | 00:04 |
erikkugel | Are you saying that they have some chip inside doing the conversion, or you just want to avoid insulting them? | 00:05 |
erikkugel | thanks for the explanation, by the way. I have 0 background, as you can tell :) | 00:05 |
wpwrak | well, the one for $6 seems to be dumb. but that's again USB-VAT5-USB, no Ether in there | 00:05 |
wpwrak | hehe, you'll learn :) | 00:05 |
erikkugel | There are also cables which seem to do the same: http://www.nextag.com/Startech-6-ft-Smart-794928856/prices-html | 00:06 |
erikkugel | You are right about a USB host being on the USB end. | 00:06 |
erikkugel | in all cases. | 00:06 |
erikkugel | so in theory, if one had to do this, they would have to write new drivers for their Ethernet card to get it to talk to a USB slave, bacuse, it takes USB host drivers to talk to a USB slave which Ethernet does not have? | 00:07 |
wpwrak | some of them may have drivers for the USB signals. but that's probably all at the physical layer, basically signal amplifiers. | 00:07 |
wpwrak | no, you need a device that talks Ethernet on one end and USB host on the other. plus a driver for driving the ethernet end. | 00:09 |
wpwrak | something like this: http://www.proxicast.com/shopping/index.php?target=products&product_id=29891 | 00:09 |
wpwrak | these are rare birds. hence the price. | 00:10 |
wpwrak | better to free up some USB port. or add a hub. | 00:11 |
erikkugel | I see. this makes more sense now... So, I can make such a cable myself to connect my ADSL modem from its Etheren jack to a PC's USB port, but I cannot do much with the nanonote because USB required a USB host which I will not have with a nanonote+ethernet combo. | 00:15 |
wpwrak | you can't connect USB host (PC) to Ether (ADSL modem) directly either. you need an USB-to-Ethernet dongle for it. but yes, they're relatively simple (probably just one major chip), so you could in theory make one yourself. | 00:18 |
wpwrak | but then, USB-to-Ether dongles are inexpensive, so why bother :) | 00:19 |
wpwrak | (i don't know what the driver situation is like, though. maybe that needs some attention.) | 00:19 |
erikkugel | I see, I can make one but I will need to buy a little board which has a chip in it and input for both ethernet and usb cabling/jacks. One last question, and I know I went beyond the Nanonote here :) - will it work on Linux, or is this what you mean by "driver situation" - it might require some proprietary software to talk to that chip? | 00:20 |
wpwrak | there are USB-to-ether dongles that work on linux. i don't know how likely it is for a dongle you pick up at the next computer shop to "just work", though | 00:23 |
erikkugel | I see, well, I'm going to hit google for the rest of it, but I really can't thank you enough for your patience and clear explanation! | 00:24 |
wpwrak | e.g., these ought to work: http://www.linux-usb.org/usbnet/#t-enet | 00:26 |
wpwrak | seems that they all use the same chip. so maybe others do, too. there's a bright side to monopolies ;-) | 00:26 |
wpwrak | you're welcome :) | 00:28 |

viric | great link! | 13:30 |
wolfspraul | lekernel: excellent writeup! congratulations! | 13:34 |
wolfspraul | that's the hardest part after such visits to give oneself a kick to upload and gallerify all pics, write a text, etc. | 13:35 |
kyak | what a great guy.. | 13:45 |
kristianpaul | very nice post indeed | 15:38 |

whitequark | wpwrak: remember I've been talking about digikey, billing/shipping/passport address and so on. They've delivered it last night nevertheless. Looks like the scan of passport was convincing enough. | 23:59 |
