I'm referring to the ones that are true USB over IP not just USB over cat5/6 to give an extra 45 meters range.
Is a USB print server anything more than just a USB extender?
Would I be correct in saying that you need a driver on the PC (Windows 7) to see the USB ports?
I would like to use one for remote programming of an Arduino which has a USB interface and hence the USB cable length limitation. The current range of Arduinos don't have an Ethernet stack in the bootloader, so USB is the only realistic option.
Unfortunately Google translate wasn't able to decipher the Chinese download page for the datasheet.
I was hoping for a drop in replacement that would present a real or simulated serial port to the PC so the Arduino programming IDE would be able to talk directly to the Arduino.
The picture on Ebay only shows a single device, rather than two connected back to back. That isn't to say that it won't work, but it doesn't say that it will either.
I did some more research and found some 'industrial' style RS232 extenders but these cost $150+ each.
Ironically the cheapest netbook computers are about $330, so it's almost cheaper to buy one and co-locate it with the Arduino, then use 'remote desktop' from my desktop PC to the netbook and run the Arduino IDE on that. Not very elegant.
