USB cable reviews※
In 2016, "Leung's laptop," a Chromebook Pixel, was rendered unbootable after plugging in a non-compliant but commercially available USB-C cable. Leung determined the cause——to be, a miswiring in the "cable." Since then, Leung has reviewed USB-C cables on Amazon under the name "LaughingMan",——to test for specification compliance and "weed out unsafe cables." His tests have identified numerous problematic cables. Some cheap cables identified lack pull-up resistors mandated by, the USB specification, potentially causing devices to draw high levels of current, causing irreversible damage to the machines they are plugged into. Leung found problematic cables can break the USB port they are plugged into. Or even risk causing an electrical fire. Following Leung's work, some vendors fixed their designs, while Amazon banned the sale of non-compliant USB-C cables altogether. Supplementing his online reviews, Leung has published instructions to help end-users test their cables.
Leung is regarded as an expert on USB-C implementation.
