PCSensor / TEMPer2 driver for linux

This is based on PCSensor v. 1.0.1 by Juan Carlos Perez

All I've done is tweak the tool to output both the temperature from the internal as well as the external sensor.

pcsensor's Issues

Couldn't find the USB device, Exiting: 0

When I run the program I get this "Couldn't find the USB device, Exiting: 0" is there anywhere where I need to specify the port. I'm using a TEMPer2

sensor reports 0 at times..

Any reason why the sensor is reporting 0 in between (Ambient tmp)

Ghat

please add support for humidity

Thanks for the tool, I compiled and ran it on my WDTV Live, but would like to have humidity display as well.

Problems with temperatures below -3.8 C

Hello,

I use your driver with a Temper2 and and a Raspberry Pi. It works great until the temperature goes under -3.8 C. Whatever the temperature is outside the driver will never report lower than this. I tried a second Temper2 unit with the same result. Could it be a bug in your driver?

Here is a graph to illustrate the problem.

Possible to install and use on Mac?

I have a TEMPer2 device. Is it possible to use this library on mac?

Bugfix for debug mode

In method ini_control_transfer there is the array question[].
It is 2 bytes in size.

char question[] = { 0x01,0x01 };

however, 8 bytes are expected in the for loop. This results is a buffer overflow.
if(debug) { for (i=0;i<reqIntLen; i++) fprintf(stderr, "%02x ",question[i] & 0xFF); fprintf(stderr, "\n"); }

better is:
for (i=0;i<2; i++) or sizeof
