"What's this!?" Hiroki stared at the familiar error message and froze for a moment.
As a former programmer, he'd run into missing drivers countless times: all kinds of off-brand peripherals, weird USB drives from the office, game controllers brought back from overseas, and so on—
When faced with a device whose driver couldn't be found, Hiroki's first instinct was—
Check the device information!
[Control Panel] → [Device Manager]
[Device Manager]—start!
Device Manager was, simply put, where Windows displayed and managed all hardware: graphics cards, sound cards, keyboards, mice, USB drives—everything plugged into the computer, along with all its components, showed up there.
Hiroki studied the list and began analyzing it line by line. "Under 'Imaging devices,' it says my two eyes were recognized as standard visual sensors, installed in the 'eye socket' slot, and working properly. That means my basic vision is fine."
By rights, if he'd replaced his own eyes with Byakugan, it should have appeared as those two standard visual sensors!
But right now, he was connecting the Byakugan through his hand—
Hiroki looked at "Universal Serial Bus controllers" and the entries beneath it.
Universal Serial Bus was what USB stood for.
This category listed all hardware related to USB ports. The Byakugan was showing up here now, which was strange!
After all, the Byakugan was a visual device. He hadn't even put it in his eye socket, so how could it count as connected?!
But considering Earth Grudge Fear's tentacles could keep moving even after leaving the main body, Hiroki supposed it wasn't that strange after all.
Besides, wasn't Rasa's Eye of Sand also not plugged into an eye socket?
Eyes seemed to work just fine outside their sockets. That wasn't so unusual, right!?
Hiroki looked at the three entries below. "'USB Root Hub'—that's the power strip
