Broken pipe

[interSAP]

Hello,
on raspberry PI, the response I have is:
sudo python ./temper.py
Traceback (most recent call last):
File "/home/admin/scripts/./temper.py", line 472, in
main()
File "/home/admin/scripts/./temper.py", line 469, in main
sys.exit(temper.main())
^^^^^^^^^^^^^
File "/home/admin/scripts/./temper.py", line 462, in main
results = self.read(args.verbose)
^^^^^^^^^^^^^^^^^^^^^^^
File "/home/admin/scripts/./temper.py", line 379, in read
results.append({ **info, **usbread.read() })
^^^^^^^^^^^^^^
File "/home/admin/scripts/./temper.py", line 304, in read
return self._read_hidraw(self.device)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
File "/home/admin/scripts/./temper.py", line 181, in _read_hidraw
firmware = self._read_hidraw_firmware(fd, self.verbose)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
File "/home/admin/scripts/./temper.py", line 149, in _read_hidraw_firmware
os.write(fd, query)
BrokenPipeError: [Errno 32] Broken pipe

and the response if requesting a --list is
sudo python ./temper.py --list
