Hello to everybody.
I have recently purchased a USB thermometer from a chinese ebay store.
The sensor has no brand whatsoever and just carries the "TEMPer" label.
I plugged it to my debian unstable box (with a vanilla 2.6.24.4 kernel)
and it was detected as
4348:5523 WinChipHead USB->RS 232 adapter with Prolifec PL 2303 chipset
I believe this means that it is, at least partly, accessible by a linux
system (although it seems to do some weird USB-serial emulation).
I am now trying to access the thermometer, and more specifically be able
to read the data it provides.
I realize this is a very broad question, but could somebody point me in
the right direction to be able to read the temperature from command
line?
The only serial experience I have is connecting to a switch's console and
configuring it with putty/minicom.
I pasted the outputs from syslog and lsusb but I dont' really see how
the latter relates to my problem.
Thanks to everyone that will respond, since now I feel quite lost.
Josh
