I purchased a usb wifi adapter that doesn't work or show up in lsusb. Here are the possible reasons I can think of why it wouldn't show up in lsusb:
- The usb port is broken
- The device is broken
- There's something wrong with lsusb
Are there any other possibilities?
I've tested all my USB ports, and they are not at fault. I've also tried it on two computers with the same results. It seems unlikely that lsusb would fail. Unless there is another possible source of error, I must assume that the adapter itself is broken.
edit: the device shows up in Windows device manager, although I'm not able to install the driver. This suggest that the device isn't actually broken, which is even more confusing.
