Created attachment 814558 [details] Script to reproduce error. sci-libs/linux-gpib-4.3.4-r1 results in a SystemError when attempting to send data to a GPIB device. A version bump to sci-libs/linux-gpib-4.3.5 and sci-libs/linux-gpib-modules-4.3.5 fixes it, as noted in the release notes: https://sourceforge.net/projects/linux-gpib/files/linux-gpib%20for%203.x.x%20and%202.6.x%20kernels/4.3.5/ The only change necessary was to comment out the first patch ""${FILESDIR}/${P}-kernel-5.17.patch" in linux-gpib-modules-4.3.5.ebuild $ cat test.py #!/usr/bin/env python3 import pyvisa rm = pyvisa.ResourceManager("@py") resource_manager = pyvisa.ResourceManager() resources = list(resource_manager.list_resources()) try: resources.remove("ASRL/dev/ttyS0::INSTR") except ValueError: pass for resource in resources: print(resource) inst = rm.open_resource(resource) inst.query("*IDN?") $ ./test.py <snip> libgpib: invalid descriptor GPIB0::1::INSTR Traceback (most recent call last): File "/home/cfg/linux/hardware/gpib/py3.10_PY_SSIZE_T_CLEAN/./test.py", line 16, in <module> inst.query("*IDN?")
