            Bug ID: 278700
           Summary: Genesys USB eMMC card reader does not see card
           Product: Base System
           Version: 15.0-CURRENT
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: usb
          Assignee: usb@FreeBSD.org
          Reporter: jfc@mit.edu

I have a USB eMMC reader, vendor 0x05e3 product 0x0727, that does not work with
FreeBSD because the kernel thinks the medium is not present.  There is in fact
a 16 GB card plugged in and the same reader+card combination works on a Mac.  I
tried copying some of the quirks for other vendor 05e3 devices with no luck. 
If there is a specific combination of quirks that should work I will try.

This reader is sold by Pine64 as a companion for their ARM and RISC-V single
board computers with eMMC connector.

In the kernel output below there is a delay of five seconds between "Attached
to scbus8" and "da0 at umass-sim0 bus 0 scbus8".
