    I can't find any resellers here in Sweden for the RJ45 to USB cable from Current Cost.

    Are such RJ45 to USB cables covered by a standard so that I could buy one from another vendor?

    It would also be great to know if it works in Linux / Ubuntu. It does. "Linux Kernel 2.4.31 and above already includes built-in drivers for PL-2303H, PL-2303XA/HXA and PL-2303HXD."

    They are not covered by a standard, but they are not uncommon. Whether one has the same pinouts as another is anybody's guess.

    Plus, note that this is not a passive cable:

    The cable includes the prolific (USB-Serial) chipset

    You could try a 4$ knock off for nokia phones that also includes the prolific chipset cut off the nokia connector and crimp a RJ45 on it as long as you got the COST pinout.

    I'm looking to get a USB to Serial cable for my Mac/Win/Linux preferably small in size and without unnecessary software installations. I've had one a while ago, it would only work with Windows. On my Mac I can just plug any USB printer or scanner and it'd just work without installing anything, so that's what I want in that USB to Serial. can someone suggest me one?

    This is the best one out there when is comes to mac compatibility. It does require some software installation though.

    It states on the amazon site linux and windows compatibility.

    It is the best for os x because of the driver support and ease of use. Every GPS owner and os x I know has always come back to this adapter for serial support. I'm sure this translates for other uses as well. There are other options out there for os x, but this one has the best support and drivers. Plus, it supports all the major OS's.

    For very high performance, low latency support FTDI usb-serial have been verified as solid on OS X. Just do a search to find numerous options. The performance measurements came from the developer of a scientific toolbox for matlab who verified sub-millisecond precision.

    Startec also make reliable usb-serial cables with OS X drivers:
