Listing other devices(TV card, capture card, etc), displaying device
status(OK or ERROR_CODE) and the ability to Enabled/Disable, might be
useful for troubleshooting.

AI:
Why it helps
•  Isolates the device — Removing the device from the kernel’s view (or 
unbinding its driver) lets you confirm whether a problem (kernel oops, high 
interrupt load, memory leaks, resource conflicts, driver hangs, etc.) is caused 
by that specific card. If the issue disappears after removal and reappears 
after rescan/rebind, the device or its driver is implicated.
•  Tests driver state — Some drivers leave hardware in a bad state. A remove + 
rescan (or unbind + bind) forces a clean re-probe and re-initialization, which 
can clear sticky errors without a full reboot.
•  Checks resource conflicts — PCIe devices share BARs, IRQs/MSI-X vectors, and 
IOMMU mappings. Temporarily removing one device frees those resources so you 
can see whether another device starts working correctly.
•  Verifies hot-plug / power behavior — On systems that support it, toggling 
the device helps confirm whether the slot, link, or power management is stable.
•  Narrows down hardware vs. software — If the device works after a clean 
re-enable but fails after a normal boot sequence, the problem is often in 
module load order, firmware loading, or udev/systemd interactions rather than 
the hardware itself.
