I recently built a new Windows 10 system with an MSI C236A motherboard using the Intel C236 chipset. It includes a USB-C port provided by an ASMedia 1142 chip, and I installed the ASMedia USB 3.0/3.1 driver, version188.8.131.52, from MSI’s downloads page. This seems to be a fairly recent driver.
I use a couple of Plugable USB 3.1 Gen 2 SATA vertical drive docks with 3.5" HDD. When I connect them to the motherboard’s native USB 3.0 ports, provided by the Intel chipset, the system uses UASP. But when I connect one to the USB-C port, the system doesn’t use UASP.
I’m wondering if this is a driver issue where the ASMedia driver simply doesn’t support UASP? I’m guessing the hardware should support it. Does Windows 10 provide a compatible driver for the ASMedia 1142 chip? Would I lose anything by uninstalling the ASMedia driver and using the Windows driver (if available)?
