To finalize it, the USB serial maintainer (Johan Hovold) needs a few details about the VDS1022: 1. Which userspace software do you use to talk to the VDS1022? In particular, is it a libusb-based tool (e.g. the Python 'vds1022' package)? This matters because once a kernel driver claims the USB interface, libusb can no longer access the device - which is the most likely explanation for the breakage you reported. 2. Could you please attach the output of: lsusb -v -d 5345:1234 for the VDS1022 (or the full 'lsusb -v' output if that fails)? The interface class reported in the descriptors decides how narrowly the driver match can be defined. 3. Does the VDS1022 support the same SCPI command set as the HDS200 series over its serial interface? I asked these questions on the mailing list thread as well, but in case replying there is inconvenient, answering here is perfectly fine - I will forward the information to the thread. A reworked version of the patch (v2) is already prepared and will be submitted as soon as this information is available. Thanks a lot for your help! --=20 You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.=
