USB2 - EHCI devices cause Windows to crash

idigdoug opened this issue · comments

Issue understood: bug in the Windows in-box usbehci.sys driver. The driver is performing atomic operations on uncached memory, which the RK3588's memory controller does not support.

Status:

  • Waiting on fix from Microsoft.

Workarounds:

  • UEFI comes with the EHCI devices disabled by default. Leave them disabled.
  • Use an XHCI port (e.g. the USB-C port on most devices) with an adapter or hub instead of using the USB2 port.
