I'm developing one TMC instrument and I get this error when - my TMC instrument is connected to Hub and Hub to pc. If I unplug and replug the USB connection for hub, I get this error. Hub is getting power from USB as well as AC-DC power adapter. If I reset the hub completely, i.e if I'm unplugging the power cord and unplugging usb connection to hub both, then plug back both, everything works fine. What could be issue in this case? I'm using Keysight IO Libraries for my development. Thanks.
