The Linux kernel includes native drivers for USB hub controllers (usbhid, xhci_hcd). You do not need a proprietary Tsupy driver. To debug:
lsusb
dmesg | grep -i usb
If the hub fails, update your kernel: sudo apt update && sudo apt upgrade.
If you installed a bad driver from a sketchy website, remove it immediately:
| ID | Issue | Severity | Workaround / Fix planned | |------|--------------------------------------------|----------|--------------------------| | T-01 | Port status interrupt may fire during reset sequence | Medium | Ignore if hub is resetting | | T-02 | Overcurrent detection on port 3 occasionally false positive | Low | Increase debounce to 150ms, hardware filter | | T-03 | SuperSpeed operation limited to 5Gbps (no Gen2) | Low | Hardware limitation |
