Just buy one of these: http://www.amazon.com/Silex-SX-DS-4000U2-Print-Server-800MHz... . Works awesome, lets you buy the cheap non-workgroup version of pretty much everything (printer, scanner, label printer, ...) and still hook it up to a central server. I have a Fujitsu ScanSnap ix500 hooked up this way, which scans directly to Dropbox. Put the scanner anywhere where it's convenient to access, put paper in it, pres…

I would argue that this benefit is probably mostly historical by now. These days, the wifi-enabled versions of at least printers is generally within less than $150 of their non-networked cousins.

TL;DR: It doesn't work. The project has been abandoned, the last update is >4 years old. Don't waste your time.

Two weeks ago I have had to implement a solution that, for technical reasons, required a usb/ip implementation so I compared everything that was available.

I spent half a day on the project, perusing mailing lists and documentation trying to get usb/ip (as linked here) to work. Eventually, I got discovery working (win7 client connecting to linux/arm server) but the connection would never be established.

Eventually, since usb/ip turned out to be a horrible waste of time, I used a professional solution for about $40 which took 5min to set up and works like a charm since then.

For a third of that price, you can get a box that's also got a built-in ethernet switch and two WiFi interfaces. You're paying a ton for software convenience.

What, a Raspberry Pi (which for that price doesn't have ethernet, wifi or a case for that matter), and on which I'll have to wait 5 minutes before the OCR is done that my central server takes 10 seconds to do; and which requires Windows 10 which didn't even exist when I first got my setup 2-3 years ago?

I'm really not sure where you're getting your specs from, but all Raspberry Pi's are a fraction of that price, come with ethernet, and don't require Windows 10. Plus the newer RPi's are quad-core ARM with 1GB RAM, which I'd wager is more than your device comes with.

I'm not trying to dismiss your device though. I do believe that it works well. But as another commenter stated, your device is priced up because of the software convenience rather than being a "bargain" in terms of hardware specifications.

Hmm I appreciate more work in this field, especially Windoze compatibility, but... as said in Star Wars: Clone Wars... "Fifty tried, fifty died". USBoIP is a minefield.

This quote comes from the kid living on Iego, where Anakin and Obi-Wan get trapped in a separatist lasernet. IIRC it was the last of the Blue Shadow Virus episodes.

I've got a couple of the Chinese made "Remote USB" servers which are interesting but not as compatible as I would like. What I find really amusing is that back when USB was proposed I argued that rather than create an entirely new infrastructure why not just use Ethernet packets. There are additional protocol types available in the bit encoding and all sorts of infrastructure that already supported layer 2 switching.…

It's been funny to watch the various phy standards converge in feature-space (alas, not interop-space) over time. PCI got a packet architecture with addresses and routing and credit-based flow control, USB got a packet architecture with addresses and routing and credit-based flow control, SATA said "screw it, we'll just become PCI-e, because they have packets and routing and flow control," and thunderbolt basically i…

Thunderbolt is PCI-e... plus DisplayPort, because we need two different serial protocols!

(And it frequently carries USB and Ethernet. So many protocols.)

what solution did you end up with (soft- or hardware?) and what devices was it supporting?

I've got a bunch of things that I'd like more switchable than standard 'kvm' type muxes can do, so curious how it worked out.

Yes, please... what did you wind up using?

Thank you. For any other searchers, Jaybo [0] says this in Episode 0202 [1] of "Star Wars: The Clone Wars" (not "Star Wars: Clone Wars" - an earlier series, of which I thought my encyclopedic knowledge had failed me, spurring my question).

Ethernet's also got the fun problem of the length of the runs being hugely different than pcie. What I expect is some kind of optical interface because of that. Optical thunderbolt might be the way for that to happen.

I thought 40G/100G ethernet was already optical (and multiplexed, much like PCIe)? EDIT: yep https://en.wikipedia.org/wiki/100_Gigabit_Ethernet I'm pretty sure that the only obstacles against "ethernet as a truly universal bus" are either minor (someone's got to invest in making adapter interfaces) or of the "why bother" variety. Unfortunately the latter is a bit of a show stopper as far as I can tell :)

Hadn't thought about 40G/100G ethernet. It'd definitely be in that same area for doing that. I'd definitely agree that the obstacles at this point are either minor or a "why bother" kind of thing. With speeds continuing to go up, I'd expect it in a generator or two simply because the "why bother" will shift the other way, why bother to make a new standard when this one does it too and is nearly ubiquitous. My guess at least for peripherials is going to be in the optical thunderbolt area, more because of the way the device network matches what people are designing for anyway. I'd guess once there's two standards, a local (optical pcie) and remote (optical ethernet), things might begin converging more and more until it's less distinct between the two.

I'd expect optical more because it's easier to get high bandwidth and low latency on interconnects than copper because of the lower crosstalk and everything. It's just a question of market forces pushing things to converge.
