I have an external usb HDD case. I needed to use it to format a drive. Having never used it before I didn’t know how well it would work. I plugged it in and ran dmesg to see if it was discovered, and the output struck me as mildly amusing.
usb-storage: device found at 5
usb-storage: waiting for device to settle before scanning
Heh, SETTLE DOWN MR. USB DEVICE!
