Yet another little usb device from PC sensors (I seem to have been giving them a fair amount of money recently ).
This is the device in question: http://pcsensor.com/index.php?_a=product&product_id=178 (note that I buy my devices via ebay where the prices are apparently always the campaign ones -- I paid AUD25 , not USD80)
It didn't come in a box so I have no scans or shots to show.
[See here for the regular TEMPer USB device (0c45:7401), and here for the TEMPer 1K4 (0c45:7403) USB thermocouple reader. Note that since the temper-usb code is in a lot of flux you can't use the line numbers in those posts directly -- you'll have to read and understand the code before pasting it in. Luckily, it's quite simple -- even I managed to sort it out!]
I couldn't get temper-usb to work even when making (what I consider) the necessary edits, but instead got lots of errors (including " usb.USBError: could not detach kernel driver from interface 1: No data available"). So I finally gave up.
Instead, web searching led me to http://edorfaus.wordpress.com/2012/07/02/new-library-examples-and-features/ -- one of the replies by eg1l spelled out the solution -- I'll grant myself the liberty to repost it here, but please remember where it originally came from and link to the original article (exclusively or in addition).
Create an 80-temper.rules file in /etc/udev/rules.d:
Then do
And
Unplug and re-plug your device, then open a new terminal and you're set (type group to make sure that users show up).
